The Ultimate Pipeline Cleaning Planning Guide
Our customers asked for a simple guide to planning a successful pipeline cleaning program—so we built one.
Every pipeline is different.
Different products.
Different debris.
Different operating conditions.
Different inspection goals.
There isn't a single cleaning pig that works for every application.
This guide explains how experienced pipeline operators plan successful cleaning programs—from the first cleaning run through final inspection preparation.
Need help planning your next cleaning program?
Our engineers review your pipeline conditions, cleaning objectives, and operating history to recommend the right pig sequence—not just a single product.

Before Choosing a Cleaning Pig, Answer These Questions
Every successful cleaning program starts with understanding the pipeline.
Before selecting a pig, ask:
✔ What product is in the pipeline?
✔ What debris needs to be removed?
✔ Is this maintenance cleaning or Pre-ILI cleaning?
✔ Has the pipeline been pigged before?
✔ Are there diameter changes?
✔ Are there tight bends?
✔ Is batching required?
✔ Is differential pressure limited?
✔ Will inspection tools follow?
The answers to these questions determine the cleaning strategy—not simply the pipeline diameter.
Step 1 – Identify the Debris
Debris
Black Powder
Paraffin
Mill Scale
Construction Debris
Liquids
Sand
Rust
Mixed Debris
Typical Solution
Magnetic cleaning pigs
Studded cups, scraping, brushes
Brushes and aggressive cleaning pigs
Heavy-duty steel pigs
Cup pigs
Disc pigs
Brushes and magnets
Multiple cleaning runsCup
Step 2 – Choose the Right Cleaning Pig Style
Once you've identified the debris and the cleaning objective, the next step is to select the cleaning pig configuration. The right choice depends on pipeline geometry, operating conditions, debris type, and whether the goal is routine maintenance or preparing for an inline inspection.
Foam Cleaning Pigs
Foam pigs are commonly used for light cleaning, drying, swabbing, and removing loose debris. Different foam densities and coatings allow them to adapt to a wide variety of pipeline conditions.

Urethane Cleaning Pigs
Urethane cleaning pigs provide excellent flexibility and sealing performance, making them well suited for routine maintenance cleaning, batching applications, and pipelines with bends or changing operating conditions.

Steel-Bodied Cleaning Pigs
Steel-bodied cleaning pigs are designed for more aggressive cleaning applications and can be configured with brushes, magnets, blades, gauging plates, and other components to remove mill scale, construction debris, heavy deposits, and other difficult contaminants.

Custom Cleaning Pig Designs
Some applications require more than a standard cleaning pig. Custom designs can be engineered for unusual debris, difficult pipeline geometry, multiple objectives, or applications where conventional cleaning pigs have not achieved the desired results.

Dual- and Multiple-Diameter Cleaning Pigs
Pipelines with reducers or multiple internal diameters often require specialized pig designs that maintain sealing and cleaning performance as the pipeline geometry changes.

Batching Separator Pigs
When different products need to remain separated or liquids need to be displaced efficiently, batching separator pigs provide reliable sealing while minimizing product mixing during pipeline operations.

Did You Know?
Many successful pipeline cleaning programs use more than one pig style. It's common to begin with one configuration to remove loose debris, then transition to more aggressive pigs with brushes, magnets, or specialized cleaning elements as the condition of the pipeline becomes better understood.nage Text button to change the font, color, size, format, and more.

Step 3 – Plan the Cleaning Sequence
This is where most operators have questions.
Example:
Initial Run
Remove loose debris.
↓
Aggressive Cleaning
Brushes
Magnets
Studded components
↓
Evaluation
Receiver inspection
Pig wear
Debris volume
Differential pressure
↓
Additional Runs
Modify configuration if needed.
↓
Gauging Run
Verify geometry.
↓
Pre-ILI Cleaning
Final preparation.
Cleaning programs are adjusted based on what each run tells you.
How Many Cleaning Runs Are Needed?
One of the most common questions we receive is: "How many pigs should we run?"
The honest answer is: It depends on what each run finds.
Some maintenance projects require only one or two runs.
Others require multiple pig configurations as debris is progressively removed.
Each run provides valuable information that helps determine the next step.
Successful pipeline cleaning is a process—not a single pig run.
Signs the Pipeline May Need Additional Cleaning
Large debris recovered
↓
Heavy black powder
↓
Paraffin still attached
↓
High differential pressure
↓
Excessive pig wear
↓
Gauge damage
↓
Inspection company recommends additional cleaning
Common Planning Mistakes
Using only one pig
Choosing based only on diameter
Skipping magnetic cleaning
Ignoring debris recovered
Running an inspection tool too early
Not modifying pig configuration
Trying to solve every problem with the same pig
Why Experienced Operators Change Pig Configurations
The first pig tells you about the pipeline.
The second pig removes what the first exposed.
The third pig often finishes the cleaning.
Each cleaning run provides new information.
That's why experienced operators frequently change:
- Cup styles
- Disc styles
- Brush configurations
- Magnet packages
- Pig weights
- Bypass settings
- Pig type
Cleaning is an engineering process—not simply launching the same pig repeatedly.
Why Customers Call Enduro
Over the years we've heard the same question hundreds of times:
"What pig should we run?"
The answer is almost never just a part number.

Sometimes a standard pig is the right answer.
Sometimes a custom configuration delivers dramatically better results.
Our goal isn't to sell the most expensive pig.
Our goal is to help you complete the cleaning program successfully.
FREQUENTLY ASKED QUESTIONS
How do I plan a pipeline cleaning program?
A successful pipeline cleaning program begins by evaluating the pipeline product, debris type, operating conditions, pipeline geometry, and the objective of the cleaning run. The cleaning strategy and pig selection should be based on these factors rather than pipeline diameter alone.
How many cleaning pig runs are usually required?
The number of cleaning runs depends on the condition of the pipeline and the amount of debris recovered after each run. Some pipelines require only one or two cleaning runs, while others need multiple pig configurations before the desired cleanliness is achieved.
How do I know which cleaning pig to use first?
The first cleaning pig is selected based on the pipeline conditions, expected debris, and cleaning objective. Operators often begin with a less aggressive configuration to evaluate the pipeline before progressing to brushes, magnets, studded cups, or other specialized cleaning components if needed.
Can the cleaning pig configuration change during the cleaning program?
Yes. Experienced operators frequently modify pig configurations based on debris recovered, pig wear, differential pressure, and the results of previous runs. Adjusting the cleaning program as conditions change often leads to better cleaning performance.
Can Enduro help recommend a pipeline cleaning strategy?
Yes. Enduro's cleaning specialists review your pipeline conditions, operating history, debris type, geometry, and cleaning objectives to recommend an appropriate cleaning pig configuration and cleaning sequence for your application.
