Pigging & Pipeline Insights

How Many Cleaning Pig Runs Does a Pipeline Need?

How Many Cleaning Pig Runs Does a Pipeline Need?

During my first year in pipeline pigging sales, I’ve learned that “How many cleaning pig runs will it take?” is one of the most common—and most difficult—questions to answer.

At first, I expected there to be a typical number of runs that applied to most pipelines. The more I’ve learned from our cleaning specialists and customers, the clearer the answer has become: it depends on what the pipeline tells you after each run.

There is no single number that works for every pipeline. Some pipelines may be ready after only a few cleaning runs. Others may require a progressive cleaning program using several pig configurations to gradually remove years of accumulated debris.

Why Isn’t There a Standard Number of Runs?

The number of cleaning pig runs needed depends on several factors, including:

The condition and operating history of the pipeline
The product being transported
The type and volume of debris present
How frequently the pipeline has been cleaned
The pipeline’s diameter, length, bends, and other features
The results recovered after each cleaning run
Whether the objective is routine maintenance or preparation for inline inspection

A pipeline that is cleaned regularly may require fewer runs than one that has not been cleaned in several years. Pipelines containing heavy paraffin, black powder, mill scale, rust, sand, construction debris, or other contaminants may require a more involved approach.

The cleaning objective also matters. A routine maintenance program may have a different stopping point than a pre-ILI cleaning program , where debris could affect the movement of an inline inspection tool or the quality of the inspection data.

What Does “Clean Enough” Mean?

One of the most important things I have learned is that “clean” can be subjective. Not every operator, technician, or service provider uses the same standard when deciding whether a pipeline is clean enough.

Some operators may stop once the amount of recovered debris has significantly decreased. Others may continue cleaning until returns are minimal or until a specific operational objective is met.

When an inline inspection is planned, the cleanliness requirements are often higher. The goal is to reduce debris that could interfere with the inspection tool, restrict its movement, affect sensor contact, or reduce confidence in the collected data.

The right stopping point should be based on the cleaning objective and the results of the individual pipeline—not simply a predetermined number of runs.

What Happens During a Progressive Cleaning Program?

A progressive cleaning program usually begins with a less aggressive pig and gradually introduces more aggressive cleaning components when needed. This helps operators manage debris loads and avoid removing more material than the pipeline’s receiving facilities can safely handle at one time.

The exact sequence will vary, but a cleaning program may include the following stages.

1. Initial Cleaning Run

The first run provides an important starting point. It can remove loose debris while helping the operator better understand what is inside the pipeline.

The amount and type of material recovered can provide useful information for planning the next run. Operators may examine whether the debris contains paraffin, black powder, rust, mill scale, liquids, sand, construction material, or other contaminants.

2. More Aggressive Cleaning

If heavier deposits remain, the next pig may be equipped with more aggressive cleaning components. Depending on the application, these could include cups, discs, brushes, scraper components, blades, or other specialized features.

Some deposits cannot—or should not—be removed in one pass. Multiple runs may be needed to gradually loosen and remove stubborn buildup while allowing the operator to monitor the volume of material being recovered.

3. Brush or Magnetic Cleaning

Brush-equipped pigs can help remove remaining material from the internal pipe wall. Magnetic cleaning pigs may also be used when ferrous debris is present.

Rare-earth magnets can collect materials such as black powder, mill scale, rust flakes, welding debris, and loose steel particles. However, magnets will not collect non-ferrous materials such as paraffin, wax, sand, or liquids. Those contaminants require other cleaning components or methods.

4. Additional Verification Runs

Once debris returns begin to decrease, additional cleaning or verification runs may be performed. Operators use the results of each run to decide whether the pipeline has met the cleaning objective or whether another pig configuration is needed.

When preparing for inline inspection, a gauge pig may also be used to help identify restrictions, dents, or reductions in internal clearance before the inspection tool is launched. A successful gauge run does not replace cleaning, but it can be an important part of confirming pipeline readiness.

5. Inline Inspection

Once the pipeline has been properly cleaned and prepared, an inline inspection tool can be run with greater confidence.

A well-prepared pipeline helps reduce the risk of debris interfering with tool movement or sensor performance. It can also support more reliable inspection results and provide a clearer picture of pipeline condition.

This sequence is only an example. Not every pipeline will need every stage, and the order or pig configuration may change depending on the application.

What Should Be Evaluated After Each Run?

Instead of focusing only on the total number of runs, operators should evaluate what happened during each pass. That may include reviewing:

The type and amount of debris recovered
Whether debris returns are increasing or decreasing
The condition of the cleaning pig after retrieval
Wear or damage to cups, discs, brushes, or other components
Differential pressure and run behavior
The pipeline’s operating conditions
The capacity of the receiver and debris-handling equipment
Whether the cleaning objective has been achieved

This information helps determine whether the next run should use the same pig, a more aggressive configuration, a different cleaning component, or no additional run at all.

Let the Pipeline Determine the Number of Runs

For me, this has been one of the biggest takeaways from learning about pipeline cleaning. I started out looking for a simple number, but successful cleaning is not about completing a predetermined number of runs or checking a box.

It is about understanding the pipeline, evaluating the results after each run, and adjusting the program based on what is being recovered.

Every pipeline is different. That is why experience, careful monitoring, and good judgment matter when developing an effective pipeline cleaning program .

Tales from the Road Episode 2

Thu, 02 Jul 2026 16:43:24 GMT

Time to Destination: The Journey Begins Long Before Field Technicians Reach the Job Site

Emrys Williams Field Technician Cell/Direct: 918-405-0541

TULSA, Okla. — For field technicians, arriving at a job site is only the final step of a much longer process. Long before an in-line inspection (ILI) smart tool enters a pipeline, technicians have already spent hours preparing equipment, inspecting vehicles, planning routes, and navigating hundreds of miles of roadway under changing conditions.

This month's edition of Tales From the Road highlights the often-overlooked challenges technicians face while traveling to project locations and emphasizes that safe driving is as critical to project success as the work performed in the field.

Following last month's discussion on project preparation—including inspecting ILI smart tools, equipment loading, and final pre-departure checks—the focus now shifts to travel planning, vehicle safety, and personal readiness.

One of the first considerations for field personnel is compliance with Department of Transportation (DOT) regulations. As a DOT-compliant company operating under a non-CDL driver program, field technicians must adhere to federal Hours of Service requirements. Drivers are limited to a maximum of 11 hours behind the wheel after taking the required rest periods, with electronic logging devices (ELDs) used to accurately record driving time.

While project schedules are typically planned to avoid reaching maximum driving limits, longer assignments occasionally require technicians to approach those limits before stopping for mandatory rest.

Before any trip begins, technicians perform a comprehensive inspection of their assigned vehicle. The inspection includes checking fluid levels, tire pressure, lighting systems, warning indicators, and the overall mechanical condition of the vehicle. Familiarity with a

vehicle's normal operation allows drivers to recognize unusual sounds, vibrations, or performance issues before they become safety hazards.

Personal protective equipment is also carefully inspected and packed before departure. Standard field gear includes fire-resistant clothing (FRC), safety glasses, steel-toe boots, impact-resistant gloves, high-visibility vests, and four-gas monitors. These monitors serve as an early warning system by detecting hazardous gases, including hydrogen sulfide (H₂S), allowing technicians to evacuate an area if dangerous concentrations are detected.

Once equipment, vehicles, and travel plans have been verified, the journey begins.

A hypothetical assignment from Tulsa, Oklahoma, to Pennsylvania illustrates the variety of challenges encountered during a typical project mobilization.

The route begins on Interstate 244 before merging onto Interstate 44 and the Will Rogers Turnpike toward St. Louis. Under ideal weather conditions, the drive appears straightforward. However, road construction quickly introduces lane reductions, active construction equipment, merging traffic, and reduced speed zones. Distracted drivers, speeding vehicles, and heavy commercial truck traffic further increase the risks.

Remarkably, many of these hazards can be encountered within the first 15 miles of travel.

As the journey continues, weather conditions may deteriorate from clear skies to heavy rain, reducing visibility and slowing traffic. Scheduled fuel stops provide opportunities for drivers to stretch, eat, and reduce fatigue before returning to the road.

After more than seven hours and approximately 400 miles of driving, additional delays caused by construction or traffic accidents may leave drivers without enough remaining hours in their electronic logbooks to continue legally. Rather than pushing beyond safe limits, technicians stop for the evening, secure lodging, and prepare for the next day's travel.

The second day begins with another complete vehicle inspection to verify that equipment remains secure and that no damage occurred overnight. Once travel resumes, technicians often encounter metropolitan traffic where congestion, aggressive driving, excessive speeding, and frequent lane changes create additional hazards.

Safe lane changes remain one of the most important defensive driving practices. Drivers are encouraged to signal well in advance, monitor mirrors, check blind spots, and complete one lane change at a time before moving into another lane. Attempting to cross multiple lanes simultaneously increases the likelihood of collisions and reduces reaction time for surrounding motorists.

Another common hazard occurs when drivers wait until the last possible moment to merge into exit lanes. These sudden movements often force surrounding traffic to brake abruptly, creating chain-reaction collisions, particularly when vehicles are following too closely.

Company leaders emphasize that defensive driving habits remain the best defense against these situations. Recommended practices include planning routes in advance, conducting regular vehicle inspections, allowing adequate travel time, maintaining safe following distances, respecting other motorists, taking scheduled rest breaks, and stretching periodically to reduce fatigue.

Unexpected challenges can also arise. Mechanical failures, for example, do not eliminate project responsibilities. When necessary, replacement vehicles—including rental trucks—may be used to ensure technicians can safely complete their assignments while maintaining project schedules.

The article also encourages employees to reflect on their own driving habits by asking themselves several questions, such as: What challenges have I faced on the road? Have any of my driving decisions increased the risk for myself or others? What changes can I make to become a safer driver? How can I contribute to a stronger culture of roadway safety?

After nearly 16 hours of travel and more than 1,000 miles across seven states, technicians eventually arrive at their destination. Although the job site marks the beginning of field operations, the work effectively began the moment the vehicle left the company yard.

For field technicians, mobilization involves much more than simply driving from one location to another. Every mile requires planning, awareness, discipline, and a commitment to safety—ensuring not only the successful completion of the project but also the safe arrival of every employee and every motorist sharing the road.

Should You Rebuild or Replace Your Pipeline Pig?

Fri, 26 Jun 2026 14:43:02 GMT

Learn how rebuild kits can extend the life of your cleaning pigs, reduce costs, and keep your pigging program running efficiently.

When I started in pipeline sales, I assumed most customers simply bought new pipeline pigs when the old ones wore out.

After all, we sell a lot of pigs. That part made sense.

What I didn't realize was just how valuable rebuild kits are—and how often rebuilding is actually the smarter choice.

As someone who's still relatively new to the industry compared to many of the experts I work with every day, I've learned that maintaining a successful pigging program isn't just about buying the right pig. It's about protecting that investment and knowing when rebuilding makes more sense than replacement.

Pipeline Pigs Are Built to Work Hard

Pipeline cleaning pigs operate in some of the toughest environments imaginable. Every run exposes them to abrasive debris like mill scale, sand, paraffin, black powder, and other contaminants while enduring changing pressures, temperatures, and miles of mechanical wear inside the pipeline.

Over time, wear components such as cups, discs, and brushes naturally begin to wear down. Even if the pig body itself remains in excellent condition, worn components can reduce sealing efficiency and cleaning performance.

That's where rebuild kits come in.

Replacing only the worn components can restore your pig's performance, extend its service life, and often cost significantly less than purchasing a completely new tool.

What Does a Pipeline Pig Rebuild Kit Include?

While every pig is different, rebuild kits commonly include replacement wear components such as:

Cups
Discs
Brushes
Fasteners
Other wear items specific to the pig design

Replacing these components restores sealing performance, improves cleaning efficiency, and helps maximize the return on your original investment.

When Should You Rebuild a Pipeline Pig?

One of the biggest lessons I've learned is that the answer isn't always "buy new."

Rebuilding often makes sense when:

The pig body is still structurally sound.
Only wear components need to be replaced.
You want to reduce costs without sacrificing performance.
You need to return the tool to service quickly.
Replacement components are readily available.

When Is Replacement the Better Option?

Sometimes replacing the entire pig is the better decision.

Replacement may be recommended when:

The pig body has sustained significant damage.
The application or pipeline conditions have changed.
The pig has reached the end of its service life.
A different pig design would provide better cleaning performance.

The key is working with a company that evaluates your tool honestly and recommends what's best for your operation—not simply what's easiest to sell.

One Size Doesn't Fit Every Pipeline

Another thing I didn't fully appreciate when I started is just how customized pigging solutions can be.

At Enduro, we don't just supply standard cleaning pigs. We design, manufacture, rebuild, and customize pigs to match each customer's specific pipeline conditions and operational goals.

Need a custom configuration? We can do that.

Need a rebuild for a pig built by another manufacturer? We can often help with that too.

Because we keep many standard pigs, rebuild kits, and replacement components in stock, customers don't always have to wait weeks to get back up and running.

Built Right Here in Tulsa

One thing I'm especially proud of is seeing where everything comes together.

Every pig and rebuild kit is designed, manufactured, assembled, and shipped from our facility in Tulsa, Oklahoma.

Watching our team work has given me a whole new appreciation for the experience, craftsmanship, and attention to detail that goes into every product we build.

It's not outsourced.

It's built by people who understand pipeline maintenance and take pride in helping customers keep their operations running.

One of my favorite things we've started offering is the opportunity for customers to visit our facility.

Whether you're new to pigging or have decades of experience, we offer facility tours, technical workshops, and Pigging 101 classes where you can see firsthand how our products are designed, manufactured, rebuilt, tested, and shipped.

It's an opportunity to ask questions, learn more about pipeline maintenance, and meet the experts who build the tools you're relying on in the field.

I think seeing the process in person gives customers a different level of confidence—not only in the products, but in the people behind them.

Get More From Your Pipeline Pig Investment

With proper maintenance and timely rebuilds, many pipeline pigs can continue delivering reliable performance for years.

That means:

Lower operating costs
Less downtime
Longer tool life
Better cleaning performance
Greater return on your investment

As someone who's still learning from the experts around me every day, this has been one of the most valuable lessons I've picked up—and one I think every pipeline operator should know.

Studded Cleaning Pig Cups: When More Aggressive Cleaning Is Needed

Tue, 23 Jun 2026 14:48:41 GMT

Understanding When Studded Cleaning Pig Cups May Improve Pipeline Cleaning Performance

Pipeline cleaning requirements vary significantly from one system to another. While standard urethane cleaning pig cups perform exceptionally well in many applications, some pipelines contain deposits and debris that require a more aggressive cleaning approach.One solution frequently used in these situations is a studded cleaning pig cup.

What Are Studded Cleaning Pig Cups?

Studded cleaning pig cups are urethane cups manufactured with metal studs embedded directly into the cup surface. As the cleaning pig travels through the pipeline, these studs provide additional scraping action that can help remove deposits that standard urethane cups may not fully dislodge.

The studs work in conjunction with the sealing and wiping action of the urethane cup, creating a more aggressive cleaning profile while still maintaining the flexibility required to navigate bends, restrictions, and pipeline variations.

Why Are Metal Studs Added to Cleaning Pig Cups?

The primary purpose of adding studs is to increase the cleaning effectiveness of the pig when operators are dealing with difficult deposits or contamination.

Potential benefits may include:

Improved debris removal
Enhanced paraffin and wax cleaning
Better mill scale removal
Increased scraping effectiveness
Improved preparation for inline inspection
More aggressive cleaning between standard pigging runs

Studded cups are often selected when cleaning goals extend beyond simple liquid displacement or routine maintenance pigging.

Common Applications for Studded Cleaning Pig Cups

Studded cleaning pig cups are commonly considered when operators encounter:

Heavy Wax or Paraffin Deposits

Paraffin buildup can reduce flow efficiency and interfere with inspection activities. The additional scraping action provided by studs may help break up and remove stubborn deposits.

Mill Scale Removal

New construction pipelines and recently modified systems may contain mill scale and manufacturing debris. Studded cups can help increase cleaning aggressiveness during commissioning or pre-inspection cleaning programs.

Pipeline Preparation for Inline Inspection

One of the most important steps before an inline inspection run is ensuring the pipeline is sufficiently clean.

Debris remaining in the pipeline can:

Obstruct sensor contact
Reduce data quality
Increase tool wear
Create unnecessary inspection challenges

Studded cups are often incorporated into cleaning programs designed to improve inspection readiness.

Difficult Cleaning Conditions

Some pipelines experience operating conditions that create recurring deposits or contamination. In these situations, operators may choose studded cups as part of a multi-pass cleaning strategy.

Are Studded Cups Right for Every Pipeline?

No.

While studded cups can provide additional cleaning capability, they are not appropriate for every application.

Factors that should be evaluated include:

Pipeline condition
Internal coating considerations
Deposit type
Cleaning objectives
Product being transported
Inline inspection requirements
Existing pigging program

Selecting an overly aggressive pig can create unnecessary wear or operational concerns, while selecting a pig that is too conservative may not achieve the desired cleaning results.

This is why many operators work with experienced pigging specialists to determine the appropriate pig configuration for their specific pipeline conditions.

Caliper Inspection vs. MFL Inspection: What's the Difference?

Thu, 04 Jun 2026 18:36:57 GMT

Caliper Inspection vs. MFL Inspection: What's the Difference?

What Is a Caliper Inspection?

A caliper inspection measures the internal geometry of a pipeline. Using mechanical or electronic sensing technology, a caliper tool records changes in the pipe's shape and identifies geometric anomalies that may affect pipeline integrity or the passage of inspection tools.

Caliper inspections are commonly used to detect:

Dents
Ovality
Wrinkles
Buckles
Mechanical damage
Bends
Geometric restrictions
Changes in internal diameter
Construction-related deformation

Caliper tools are often run during new pipeline commissioning, before inline inspection programs, or whenever pipeline deformation is suspected.

What Is an MFL Inspection?

Magnetic Flux Leakage (MFL) inspection is designed to identify metal loss and corrosion-related threats within a pipeline.

MFL tools magnetize the pipe wall and measure changes in the magnetic field caused by metal loss. These measurements allow analysts to identify areas where corrosion or wall loss may be present.

MFL inspections are commonly used to detect:

Internal corrosion
External corrosion
Metal loss
Pitting
General wall thinning
Corrosion growth

MFL technology provides critical information about pipeline wall condition and remaining wall thickness.

Pipeline operators have access to a wide range of inline inspection technologies, each designed to identify specific pipeline conditions and integrity threats. Two of the most commonly used technologies are caliper inspections and Magnetic Flux Leakage (MFL) inspections.

While both technologies play important roles in pipeline integrity management, they are designed to detect different types of features and are often used together as part of a comprehensive inspection program.

Caliper Inspection vs. MFL Inspection

Although both technologies are used during inline inspection programs, they serve different purposes.

Caliper Inspection

MFL Inspection

Measures pipeline geometry

Detects dents and deformation

Identifies wrinkles and buckles

Evaluates ovality

Helps confirm tool passage

Focuses on geometric integrity

Measures metal loss

Detects corrosion and wall loss

Identifies pitting and corrosion growth

Helps assess corrosion severity

Focuses on metal loss integrity

Simply put, a caliper tool evaluates the shape of the pipeline, while an MFL tool evaluates the condition of the pipe wall.

Why Many Operators Use Both Technologies

Pipeline integrity threats rarely occur in isolation.

A pipeline may contain:

Corrosion
Dents
Mechanical damage
Wrinkles
Buckles
Ovality

Using both caliper and MFL technologies provides operators with a more complete understanding of pipeline condition.

For example:

A caliper inspection may identify a dent caused by third-party damage.
An MFL inspection may determine whether metal loss is also present in the affected area.

Together, these technologies help operators make more informed integrity management decisions.

Why Pipeline Cleaning Matters Before Either Inspection

Regardless of the inspection technology being used, pipeline cleanliness plays a significant role in inspection success.

Debris, liquids, paraffin, mill scale, construction debris, and other contaminants can interfere with tool performance and impact inspection data quality.

Proper cleaning before a caliper or MFL inspection can help:

Improve tool passage
Reduce debris interference
Improve data quality
Reduce operational risk
Support more reliable inspection results

Many operators perform multiple cleaning runs before inspection activities to help ensure optimal tool performance.

Choosing the Right Inspection Technology

The appropriate inspection technology depends on the objectives of the inspection program.

If the goal is to identify dents, wrinkles, buckles, or geometric deformation, a caliper inspection may be appropriate.

If the goal is to assess corrosion, metal loss, or wall condition, an MFL inspection may be the preferred solution.

In many cases, operators use both technologies to obtain a more complete understanding of pipeline condition and support long-term integrity management programs.

Tales from the Road

Mon, 01 Jun 2026 13:55:21 GMT

TALES FROM THE ROAD

Emrys Williams Enduro Field Technician

Behind Every Successful ILI Run Is a Team That Started Preparing Long Before the Tool Ever Entered the Launcher.

When most people think about an In-Line Inspection (ILI) project, they picture the launch of a sophisticated inspection tool, miles of pipeline, and the valuable integrity data gathered at the end of the run. What often goes unseen is the extensive preparation that takes place before a field technician ever arrives at the launch site.

In the first installment of “ Tales from the Road ”, we take a closer look at what it takes to prepare for mobilization and why preparation is one of the most critical phases of any successful pipeline integrity project.

Every Pipeline Is Different :

One of the first realities an ILI technician learns is that no two launchers, receivers, or pipeline systems are exactly alike. Before a project begins, technicians must verify that both the launcher and receiver can safely accommodate the inspection tool selected for the survey.

This includes reviewing:

• Launcher and receiver dimensions

• Isolation trap configurations

• Pipeline wall thicknesses

• Product flow characteristics

• Line operating conditions

• Tool length and operational requirements

Much of this information is gathered by project managers and engineering teams and compiled into detailed "running orders." These documents serve as the roadmap for field personnel, transforming technical project data into actionable information that technicians can use in the field.

Turning Information into Action:

Experienced field technicians do more than simply follow instructions—they analyze them.

Every project presents unique challenges, and technicians must compare project specifications against the inspection tool's capabilities to ensure the survey can be completed successfully.

The ultimate mission is straightforward: Get the Data. Get the Data Accurate.

Everything else revolves around achieving that goal.

The Importance of Tool Verification.

An inspection tool is only as effective as its ability to collect reliable data.

Before mobilization, technicians verify numerous factors, including:

• Sensor functionality

• Battery capacity

• Data recording capability

• Magnetic flux leakage (MFL) performance

• Tool bypass configurations

• Mechanical integrity of all components

At Enduro Pipeline Services, inspection tools undergo rigorous testing through standardized pipe sections containing known anomalies. These test pulls verify that sensors accurately identify and record defects before deployment to the field.

If any deviations are discovered, corrections are made immediately, and testing continues until performance meets the required standards.

Calibration: The Foundation of Accuracy.

Every sensor and every component undergoes a detailed calibration process.

Calibration ensures that the inspection tool can accurately identify and measure pipeline features and anomalies under real operating conditions. These calibrations are verified before each test pull, creating confidence that the tool will perform as expected once it enters the customer's pipeline.

By this stage, the preparation effort has already involved a significant number of professionals, including:

• Tool builders

• Engineers

• Programmers

• Logistics coordinators

• Project managers

• Field technicians

An ILI run is never the work of one individual—it is the product of an entire team.

Mobilization : The Final Phase Before Departure.

Once all technical checks are complete, field technicians begin loading the inspection tools and support equipment required for the project.

Depending on the scope of work, equipment may be transported using:

• Service trucks

• Utility trailers

• Gooseneck trailers

• Specialized transportation equipment

Every item is secured, documented, and inspected in accordance with internal fleet and logistics procedures before departure.

Only then is the team ready to mobilize.

The Side of the Job Few People See: For many technicians, preparation extends beyond tools and equipment.

It also means preparing to spend days, weeks, or even months away from home.

Field technicians frequently miss birthdays, holidays, family events, and ordinary moments that most people take for granted. Behind every successful project is a family making sacrifices and providing support from home.

These families are often the unsung heroes of the pipeline integrity industry.

No matter how long a project takes, they remain waiting, supporting, and welcoming their loved ones home after another successful mission.

When the Project Is Completed: One phrase is commonly heard among field technicians before departure: "We'll be back when the project is completed." Not tomorrow. Not next week. When the project is completed.

That commitment reflects the mindset of the industry: whatever it takes, however long it takes, the job will be completed safely, accurately, and the right way the first time.

A Tribute to the Field Technician: Being an ILI field technician is not for the faint of heart.

It requires:

• Commitment

• Determination

• Technical expertise

• Adaptability

•Perseverance

Every day, technicians face new challenges in environments where accuracy matters and failure is not an option.

To every field technician working in pipeline integrity: We sacrifice. We endure. We adapt. And every time, we get it done. Thank you for everything you do.

What Problem Does a Dual Diameter Cleaning Pig Solve?

Fri, 24 Apr 2026 14:52:07 GMT

What Problem Does a Dual Diameter Cleaning Pig Solve?

How a Dual Diameter Cleaning Pig Solves the Problem

A dual diameter cleaning pig is designed specifically for pipelines that change diameter.

Instead of being built for a single diameter, it is engineered to adjust as it moves between different pipe sizes while maintaining a working seal.

The key isn’t just that it can physically pass through both sections—it’s that it continues to clean effectively throughout the entire run.

It maintains contact with the pipe wall as the diameter changes, resulting in more consistent cleaning from start to finish.

Pipeline pigging is usually straightforward when a line stays the same size from end to end. The pig is selected for that diameter, it seals properly, and it moves through the pipe doing its job.

The challenge shows up when the pipeline changes size.

A section might transition from 24” to 30”, or the other way around, due to expansions, tie-ins, or older infrastructure being connected into newer systems. That’s where standard cleaning pigs start to fall short.

A standard cleaning pig is designed for a single consistent pipe diameter. When it encounters a change in size, it can no longer maintain a proper seal against the pipe wall.

In larger sections, the pig can lose sealing force, allowing product and debris to bypass it rather than being pushed forward. In smaller sections, it can become overly compressed, which affects performance and stability. Either way, the cleaning becomes inconsistent.

Even if the pig makes it through the entire line, the results are uneven. Some areas are cleaned effectively, while others are not—and those gaps can show up later as buildup, reduced flow, or unexpected maintenance issues.

For a closer look at standard cleaning tools, see our pipeline cleaning pigs page.

What's the difference between Dual Diameter and Multiple-Diameter Pigging Systems ?

Why Design Matters More Than People Think

What many people underestimate is how difficult that balance actually is.

If a pig is too stiff, it can struggle to transition between diameters.
If it’s too flexible, it may pass through—but won’t maintain enough sealing force to clean effectively.

A properly designed dual-diameter pig has to strike that balance:

Flexible enough to transition smoothly
Stable enough to maintain position
Strong enough to keep an effective seal

That balance doesn’t happen by accident—it comes from real-world experience.

Not All Dual Diameter Pigs Perform the Same

Over the years, many companies have tried to replicate dual-diameter pig designs.

But while designs can be copied, experience cannot.

At Enduro Pipeline Services, our dual-diameter pigs are based on a proven design refined through years of field work, tool development, and solving real pipeline challenges.

Because we don’t just design these tools—we manufacture them, run them, and see how they perform in actual pipeline conditions—we understand what works and what doesn’t.

That’s something that can’t be duplicated, and it’s why the original design continues to outperform.

Built for Real Pipeline Conditions

Pipeline conditions are rarely perfect.

Diameter changes are often combined with:

Debris
Flow variations
Operational constraints

That’s why dual diameter pigs need to do more than just pass through the line—they need to perform under real conditions.

At Enduro, these tools are designed, built, and tested with that in mind. Not just to get through the pipeline—but to do the job the entire way.

Why This Matters to Operators

Dual diameter pigs exist for one simple reason:

Pipelines don’t always stay the same size—but cleaning still has to be reliable from end to end.

When the right tool is used, operators get:

More consistent cleaning
Fewer missed sections
Better preparation for inspection
Fewer surprises after startup

Taking the Guesswork Out of Pig Tracking with Enduro's Non-Intrusive Pig Signal

Tue, 14 Apr 2026 14:46:33 GMT

Understanding how non-intrusive pig tracking improves visibility, efficiency, and confidence in the field

If you’ve ever been out in the field trying to track a pig through a pipeline, you know how quickly things can get complicated. Conditions aren’t always ideal—visibility can be poor, locations are often remote, and setups are sometimes only temporary. In moments like that, even a small bit of uncertainty can slow everything down. That’s exactly the kind of situation the Enduro Non-Intrusive Pig Sensor was designed for.

Instead of relying on traditional setups that require cutting into the pipeline or running wires, the unit keeps things simple. It mounts directly to the outside of the pipe, so there’s no hot work, no modifications, and no drawn-out installation process. You can get it in place in seconds and just as easily move it if the job changes.

That flexibility makes a real difference when you’re working in temporary locations, valve sites, or stretches of line where setting up permanent equipment just isn’t practical. You’re not tied down—you can place the sensor where you need it and adjust as you go.

When the pig passes, the sensor detects its magnetic field and provides a clear visual alert. It’s immediate and easy to read, which removes a lot of the second-guessing that can happen in the field. You don’t have to wonder if you missed it or if something didn’t trigger correctly—you know right away. Because everything happens externally, the system also stays consistent across different conditions. Whether it’s a routine cleaning run or a more critical inspection, you get the same straightforward signal every time.

What stands out most about Non-Intrusive Pig Signal is how much simpler it makes the job. It cuts down setup time, reduces equipment complexity, and lets you focus more on the actual run instead of the tools around it. One unit can even be used across multiple locations, which helps when you’re moving between jobs or coordinating across sites.

At the end of the day, it’s not about adding another piece of equipment—it’s about removing uncertainty. Attach it, align it, and watch for the alert when the pig passes. That’s really all there is to it. And when you’re the one out there in the field, that kind of simplicity goes a long way.

A few tips and tricks from our engineers behind the product: Operators should regularly inspect and replace batteries to ensure uninterrupted operation. It’s also important to confirm proper unit placement to avoid external magnetic or electrical interference. Additionally, providing Enduro with feedback based on field experience can help drive continuous product improvement.

As always, our team of experts is here to help. Call 800-752-1628 or you can order these units 24/7 directly from our Shopify store: Non-Intrusive Pipeline Pig Sensor – Enduro Pipeline Services .

What type of pig do I need for wax removal?

Wed, 01 Apr 2026 19:10:12 GMT

How to choose the right pipeline pig based on wax buildup, flow conditions, and real-world operating challenges

Best Pig for Wax Removal:

For most pipelines, urethane pigs and brush pigs are the most effective for removing wax buildup. The right choice depends on wax severity, flow rate, pipeline geometry, and the level of aggressiveness required for cleaning.

Why Wax Buildup Is a Bigger Problem Than It Looks

Wax buildup doesn’t just restrict flow—it creates a chain reaction of operational issues that can impact efficiency, inspection accuracy, and even pipeline integrity.

As wax accumulates along the pipe wall, it:

Reduces flow efficiency and increases pressure requirements
Creates inconsistent internal surfaces that affect pig performance
Interferes with inline inspection (ILI) tools, leading to poor or unreliable data
Increases the risk of stuck pigs or incomplete cleaning runs

And here’s where most operators run into problems— they choose the wrong pig for the conditions.

Too light, and it won’t remove the buildup.
Too aggressive, and it can bypass, wear out prematurely, or create unnecessary risk.

Why Pig Selection Matters

There’s no one-size-fits-all solution for wax removal.

The most effective cleaning programs are built around real pipeline conditions , including:

Wax type and severity
Pipeline diameter and wall condition
Flow rate and pressure
Bend radius and restrictions

This is why understanding the differences between pig types—and when to use each—is critical to getting the job done right the first time.

Urethane Pigs (Best for Moderate to Heavy Cleaning + Sealing)

For most wax removal applications, urethane pigs offer the best balance of cleaning performance and sealing capability .

They’re more durable than foam pigs and can be configured with cups, discs, brushes, or scraper elements depending on the job.

Best for:

Moderate to heavy wax buildup
Maintaining consistent contact with the pipe wall
Pipelines requiring both cleaning and sealing

Why they’re widely used:

Hold their shape under pressure
Provide consistent cleaning performance over longer runs
Can be customized for specific pipeline conditions

Foam Pigs (Best for Light Maintenance Cleaning)

Foam pigs are often used for lighter cleaning applications or routine maintenance , but they’re not typically the best choice for heavy wax removal.

Their flexibility allows them to navigate tight bends and restrictions, but they lack the aggressive cleaning power needed to remove tougher deposits.

Best for:

Light wax buildup
Maintenance runs between more aggressive cleanings
Systems with tight bends or diameter changes

Limitations:

Lower durability
Less effective on hardened or thick wax

Foam pigs can play a role—but relying on them for heavy wax removal often leads to incomplete cleaning and repeat runs .

What Most Effective Cleaning Programs Look Like

In real-world operations, wax removal is rarely a one-pass solution.

The most effective approach often includes:

Initial run with a brush pig to break up heavy deposits
Follow-up runs with urethane pigs to remove remaining debris and condition the line
Additional runs as needed to achieve inspection-ready conditions

Need Help Selecting the Right Pig?

Every pipeline is different—and choosing the right pig upfront can save time, reduce risk, and avoid costly reruns.

Common Mistakes Operators Make When Removing Wax

Wax removal seems straightforward—but in practice, it’s one of the most common areas where pigging programs fall short. Most issues don’t come from the pipeline itself… they come from incorrect assumptions and pig selection.

1. Choosing a Pig That’s Too Light for the Job

One of the biggest mistakes is underestimating how much wax is actually in the line.

Operators often start with foam pigs or lighter cleaning tools thinking they’ll “see how it goes”—but this usually results in:

Incomplete cleaning
Multiple unnecessary runs
Wasted time and increased costs

If wax buildup is moderate to heavy, starting with a more aggressive solution (like brush or properly configured urethane pigs) is usually the better approach.

2. Trying to Solve Everything in One Run

Wax removal is rarely a one-pass job—especially in pipelines with significant buildup.

Trying to remove all deposits in a single run can lead to:

Debris accumulation in front of the pig
Increased risk of stalling or bypass
Inconsistent cleaning results

The most effective programs use a multi-run approach , gradually removing buildup and conditioning the pipeline.

3. Ignoring Flow Conditions

Even the right pig won’t perform if flow conditions aren’t properly considered.

Issues like:

Inconsistent flow rates
Low velocity
Pressure fluctuations

…can all impact how effectively a pig removes wax and transports debris.

Pig performance isn’t just about design—it’s about how it interacts with real operating conditions.

4. Not Preparing Properly for ILI

This is a costly one.

If wax isn’t fully removed before an inline inspection (ILI) run, it can:

Interfere with tool sensors
Reduce data accuracy
Lead to reruns and additional downtime

Proper cleaning isn’t optional—it’s critical for reliable inspection results .

5. Using a “Standard” Pig Instead of a Custom Solution

Not all pipelines are the same—so using an off-the-shelf pig without considering:

Diameter changes
Bend radius
Wax characteristics
Operating conditions

…can limit performance.

The best results come from pigs designed around actual pipeline conditions—not guesswork.

Bottom Line

Wax removal isn’t just about running a pig—it’s about running the right pig, in the right sequence, under the right conditions.

Getting it wrong leads to:

More runs
More downtime
Higher costs

Getting it right means:

Faster cleaning
Better flow efficiency
Reliable inspection results

Enduro's Wireless Geophone

Thu, 29 Jan 2026 14:51:42 GMT

Built for the field

McKenzee O'Neal- Product Sales

At Enduro, our Wireless Geophones are built by people who understand how they’re used in the field. Having spent years assembling and inspecting these units firsthand, I’ve seen the level of care and precision that goes into every component—and I know who’s relying on them once they leave our hands.

Accuracy, consistency, and reliable tracking are at the center of how Enduro geophones are built. Every unit is designed to capture precise motion data so crews can trust that their measurements reflect exactly what’s happening on the ground. From sensor alignment and internal assembly to final testing, each geophone is put together with the goal of delivering high-quality, actionable tracking data in real field conditions. This isn’t just about meeting specifications—it’s about supporting confident decisions in the field and giving crews the tools they need to work efficiently and effectively.

Every design and assembly decision is made with the field in mind. Enduro geophones are built to integrate smoothly into workflows, maintain precise timing, and provide clear, consistent tracking throughout the job. That attention to detail reflects our respect for the crews who rely on this equipment every day. Knowing that the data collected is accurate and reliable helps teams make better decisions on the spot, whether they’re adjusting layouts, troubleshooting equipment, or analyzing measurements.

Wireless design further supports field operations. By eliminating cables, Enduro geophones allow crews to deploy efficiently, adapt to challenging terrain, and maintain flexible layouts without added complexity. The freedom to move units quickly and easily gives survey teams the flexibility to handle unexpected obstacles, reach difficult locations, and respond to changing conditions—all while maintaining consistent tracking and data collection across the survey area.

Tracking is more than just a measurement—it’s the foundation for actionable insights. When geophones consistently capture motion data with precision, crews can have confidence that the information they’re seeing reflects the site's reality. That reliability reduces guesswork, keeps surveys on schedule, and ensures that the results collected can be used with confidence for analysis, reporting, or operational decisions.

At Enduro, we don’t just design geophones—we build them with the people in the field in mind, knowing that accurate tracking and reliable data start with equipment assembled with care and purpose. Every unit that leaves our shop is intended to make fieldwork smoother, faster, and more precise for the teams who rely on it.

Tips & Tricks for Enduro Geophones

Check power first: If your geophone isn’t turning on, confirm the batteries are installed correctly and have sufficient charge.
Remove batteries for storage: Always take batteries out during storage to prevent corrosion and extend battery life.
Charge accessories: Make sure the headphone set and speaker are fully charged before assuming there’s an issue with the unit.
Power off after use: Turn the geophone off and remove the batteries before transport or storage.
Ensure proper contact: For the best tracking accuracy, seat the geophone firmly and orient it correctly on the ground.
Avoid loose or uneven surfaces: Place units on solid ground to maintain consistent measurements.

The Evolution of Pipeline Pigs

Fri, 26 Sep 2025 13:25:41 GMT

From Squeals to Smart Tech: The Evolution of Pipeline Pigs

If you’ve ever wondered why a high-tech pipeline tool carries the humble name “pig,” the answer takes us back more than a century—when pipeline cleaning was loud, messy, and surprisingly inventive.

The Squealing Origin

The earliest “pigs” were nothing like today’s precision-engineered tools. Pipeline operators stuffed straw bales or leather bundles wrapped in barbed wire or metal discs into their lines to scrape away wax, rust, and other buildup. As these makeshift devices rattled along, friction against the pipe wall created a piercing squeal. Crews said it sounded like a pig in distress—and the name stuck.

From Crude Cleaners to Engineered Solutions

Over time, operators refined these tools into purpose-built cleaning pigs. Instead of straw and wire, urethane cups and discs became standard, providing better sealing and consistent cleaning action. Enduro has carried that spirit of innovation forward with a full line of urethane and specialty cleaning pigs designed to tackle everything from heavy black powder to stubborn scale in pipelines from 2" to 60".

Cup Pigs and Disc Pigs : Reliable, economical options for routine debris removal.
Wire-Brush and Magnetic Pigs : Ideal for rust, mill scale, or black powder.
Custom Builds : Enduro engineers design pigs to match unique diameter changes, bends, or pressure conditions—because no two pipelines are alike.

The Rise of “Smart Pigs”

Cleaning eventually paved the way for inspection. Operators began adding sensors and electronics to record pipeline conditions as the pig traveled. These “intelligent” or “smart pigs” now map corrosion, measure wall thickness, and detect tiny cracks—all without shutting down the line.

Enduro supports this next step too. A clean line is critical before any in-line inspection (ILI) run, and our cleaning pig programs prepare pipelines for the most accurate smart-pig data —saving time, money, and potential re-runs.

Why Cleaning Still Matters

Even in the age of sophisticated ILI tools, effective cleaning is the foundation of pipeline integrity . Residue or liquids left behind can compromise sensor readings and create costly delays. That’s why Enduro’s Cleaning Division offers:

Expert Consultation : We evaluate every line’s history, product, and operating pressure to recommend the right pig and cleaning sequence.
Quick Turnaround : Most standard pigs ship same day, and custom orders are fast-tracked from our Tulsa, Oklahoma manufacturing facility.
Proven Reliability : Backed by decades of field success and a 96% “extremely satisfied” customer rating.

Keep Your Pipeline Running at Its Best

From the squeal of straw bales to the quiet efficiency of today’s smart technology, pipeline pigs have come a long way. Yet the core mission remains the same: keep product moving safely and efficiently .

Whether you need a simple urethane cup pig or a complete pre-ILI cleaning program, Enduro Pipeline Services is here to help.

Choosing the Right Cleaning Pig: A Pipeline Operator’s Perspective

Fri, 22 Aug 2025 18:14:10 GMT

Custom Pipeline Cleaning Pigs and Programs Designed for Your Line

This article was written by Chris Escoe, Senior Product & Technical Specialist at Enduro, with over 20 years in pipeline pigging and cleaning.

After more than 29 years in the pipeline industry, I’ve learned one simple truth: no two pipelines are alike, and no two cleaning programs should be either. Every operator wants the same thing — reliable performance, fewer surprises, and inspection runs that don’t fail because of debris or preparation issues. But the way you get there depends on your pipeline’s unique conditions.

That’s why at Enduro, we don’t just build cleaning pigs. We work with operators to design custom cleaning solutions that align with the pipeline, the debris load, and the long-term integrity management goals.

Start With the Pipeline, Not the Pig

When operators ask me what cleaning pig they should run, my first question back is simple: What’s in your line?

Is it paraffin, scale, black powder, or mixed debris?
Are you preparing for in-line inspection, or just keeping flow efficient?
What kind of bends, valves, and diameter changes do we need to plan for?

The answers shape everything that follows. A brush pig can scrape deposits that a foam pig would glide past, while a magnet pig will pick up ferrous debris that brushes won’t touch. Sometimes you run them together, other times separately — it all depends on the cleaning objective.

Custom Configurations That Work

I’ve spent my career designing custom cleaning plans because operators can’t afford cookie-cutter answers. Maybe your pig needs six discs for control, or maybe it needs added brush and magnet assemblies for a tough debris load. Perhaps a bi-directional design is suitable for your system, or perhaps it isn’t. The goal is always the same: a pig that’s built for your pipeline, not just for the catalog.

That’s the advantage of Enduro’s Pipeline Cleaning Pig Division. We’ve got a team with more than 80 years of combined cleaning experience, and we thrive on tackling the toughest challenges operators face.

Why I Love This Work

For me, pipeline pigging isn’t just about tools — it’s about teamwork. I’ve built strong friendships in this industry, and I value every chance to speak with an operator, talk through their challenges, and help find a solution.

My background as a former athlete taught me that persistence and preparation are just as important as performance. That’s how I approach every project: plan hard, work hard, and keep the customer first.

As I like to say: “The will to prepare to win is just as important as the will to win.”

Let’s Talk About Your Line

If you’re facing a tough cleaning challenge, you don’t have to figure it out alone. Our Cleaning Pig Division is here to help you design the right configuration, get tools delivered on time, and keep your operation moving.

Buried in Crud: The Real Cost of Skipping Proper Cleaning

Tue, 29 Jul 2025 16:14:24 GMT

Would You Still Run That ILI Tool If You Knew What Was Waiting in the Receiver?

We’ve all seen the photos — ILI tools coming back completely buried in gunk. Thick, sticky, caked-on debris. And every time I see one, I can’t help but ask myself:

If the operator knew the tool would come out looking like this... would they have run it in the first place?

Here’s one of those photos from a crude line that hadn’t been cleaned properly before the inspection. Take a close look at the MFL detection section — specifically the sensor assembly just above the yellow moment arms. Those shiny little tabs are designed to stay in direct contact with the pipe wall. Any lift-off from debris? Your data’s already compromised.

These tools rely on clean, consistent background magnetization to calculate accurate metal loss readings. If debris is keeping the sensors off the wall, not only is your baseline wrong, but the peak values of leakage (the whole point of the run) are skewed too. Bottom line: you’re not getting the data you need .

So, what’s the fix?

In line conditions like this, a few foam pigs or basic brushes just aren’t going to cut it. Odds are, you’ve got hard wax or paraffin bonded to the pipe wall. Sure, you can try brushing — but in this environment, those brushes will pack up fast and quit doing their job halfway down the line.

You need more.

We’re talking chemical cleaning, combined with the right tools. Heavy-duty cleaning pigs . Tandem-section tools that bring weight, muscle, and more cleaning surface to the fight. And even then, don’t send them in first. You’ve got to pig in stages , building up with each run. Otherwise, your receiver’s going to be overwhelmed by the sheer volume of debris.

In some cases, xylene flushes are an excellent option to break up wax and allow cleaning tools to work more effectively. Just don’t waste your time on foam pigs in a mess like this — they won’t make a dent.

If it’s your name on the ILI schedule and you’re prepping a crude line that hasn’t seen proper maintenance, do yourself a favor: talk to your service provider before the run.

This is exactly what we deal with at Enduro, day in and day out. From chemical cleaning strategies to tool selection, we help operators get these lines ready — because if the cleaning isn’t done right, the ILI team can’t do their job. It’s a hand-in-glove operation.

Get it done right the first time, and everybody wins.

Ensuring Pipeline Integrity Starts with Proper Cleaning

Fri, 25 Jul 2025 16:39:45 GMT

Choosing the Right Pig for the Job.

With over 30 years of experience in pipeline operations, I’ve seen firsthand how essential proper cleaning is to pipeline integrity. Whether you're transporting crude oil, refined products, or gas, a proactive pigging program isn’t just recommended—it’s foundational.

At Enduro, I work closely with operators facing complex cleaning challenges. When the job gets tough, I help customers select the right solution for their system's debris, configuration, and operational demands.

Choosing the Right Pig for the Job. In the above photos we’ve shared, you’ll see examples of heavy ferrous debris—material that can severely compromise flow efficiency and inspection quality.

To address this type of contamination, I typically recommend:

Rare-earth magnet-equipped pigs to attract ferrous material
Multiple runs to account for magnet saturation
Combination pigs with cups and discs for both scraping and sweeping
Increased pig weight for enhanced scraping force
Additional cleaning elements (extra cups, discs, or brushes)
Multi-section pig trains for heavily contaminated lines

Maintaining a consistent speed of 2–5 MPH is critical. Pigs should be run until debris levels significantly taper off and magnets indicate minimal remaining material.

Establishing a Cleaning Schedule. A successful pigging program starts with establishing a clean baseline. Once debris levels are reduced, set a routine cleaning frequency.

If quarterly runs still retrieve large volumes of debris, it's a clear indicator that your schedule needs adjustment. Regular cleaning minimizes risk, supports efficient operation, and ensures your system is always ready for inline inspection (ILI).

Clean Before You Inspect. Ferrous debris can have a direct, negative impact on ILI tool performance, causing: • Sensor lift-off • Odometer wheel inaccuracies • Magnet section saturation.

These issues lead to poor data, failed inspections, and costly reruns. Cleaning prior to ILI isn’t optional—it’s an operational requirement.

Pipeline integrity doesn’t start with inspection. It starts with cleaning.

If you're unsure which cleaning pig is best suited for your system, our team is ready to assist you. I invite you to discuss your project needs with us, whether through a phone call, email, or by visiting our headquarters in Tulsa. During your visit, you'll have the chance to tour our manufacturing facility, learn more about our products and services, and work with our experts to create a customized cleaning solution tailored to your specific project.

The Innovation Behind Enduro's new Dynamic Speed Control (DSC 2.0)

Fri, 25 Jul 2025 16:28:19 GMT

High-Flow Pipelines Demand Smarter Solutions

Why is maintaining throughput during pipeline operations so critical? Throughput has a direct impact on operational efficiency and revenue. However, certain activities—such as in-line inspections (ILI) and cleaning—require significantly lower tool speeds to be effective. That creates a challenge, especially in high-flow gas pipelines, where reducing flow just to slow down the tool isn't always feasible.

What speed ranges are ideal for ILI and cleaning tools? For effective cleaning, the optimal speed is between 2 and 5 mph. For in-line inspections, the ideal range is 3–6 mph. Staying within these ranges is key to getting accurate data and thorough cleaning.

How does Enduro’s DSC 2.0 help address this challenge? The Dynamic Speed Control (DSC 2.0) system allows our tools to operate at optimal velocities without requiring flow reduction. It’s a game-changer for operators who want to maintain production rates while achieving high-quality inspection and cleaning.

What makes the DSC 2.0 different from other solutions? It’s a compact, standalone unit that integrates speed control with a high-performance cleaning tool. It was developed using advanced 3D modeling and CFD (Computational Fluid Dynamics) engineering, so it’s designed to perform in demanding environments.

What are the biggest benefits operators see with DSC 2.0? There are several:

No need to reduce flow to hit target tool speeds
Improved ROI and reduced downtime from better data and fewer re-runs
Smart speed control , which helps avoid speed spikes that compromise performance
A compact, economical design that’s easy to deploy
Full compatibility with Enduro’s cleaning and ILI tools
It’s ideal for systems where reducing flow isn’t an option

What types of pipelines are best suited for DSC 2.0? It’s perfect for high-flow systems where adjusting throughput isn’t feasible.

What’s the bottom line for operators considering DSC 2.0? With DSC 2.0, you don’t have to choose between efficiency and data quality. You get both. It’s a smart, cost-effective way to maximize performance without compromising your operations.
