Large Diameter Pipeline Cleaning Pigs with brushes and magnets

Large Diameter Pipeline Cleaning Pigs

(36”–60”)

Built for Bigger Pipelines.

Backed by Real-World

Experience.




When pipelines reach 36 inches and above, everything changes.

Flow rates increase. Forces multiply. Cleaning becomes more complex. And the margin for error gets smaller.

Large diameter pipelines don’t just need bigger tools—they need better-designed tools.

At Enduro Pipeline Services, we specialize in cleaning pigs for all sizes and configurations, including large-diameter tools engineered to meet the added demands of 36-inch to 60-inch pipelines. From crude and refined products to natural gas systems, our team designs and manufactures pigs that maintain seal integrity, remove debris effectively, and stay stable over long distances.

Why Large Diameter Pipelines Require a Different Approach

Running pigs in large diameter lines introduces challenges you won’t see in smaller systems:

  • Maintaining consistent sealing across long distances
  • Managing higher velocities and differential pressures
  • Preventing tool instability or “lift-off”
  • Removing heavier volumes of debris, wax, or scale
  • Navigating bends, valves, and diameter transitions

These aren’t theoretical problems—they’re field realities.

That’s why every large diameter pig we build is designed with performance, durability, and reliability in mind from day one.

Custom Cleaning Pigs for 36”–60” Pipelines

We design and manufacture a full range of large diameter cleaning pigs at our Tulsa, Oklahoma headquarters, including:

Aggressive Cleaning Pigs

Built for heavy debris loads, mill scale, black powder, and construction cleanup.

Bi-Directional Cleaning Pigs

Reliable performance in either direction for filling, displacement, and maintenance operations.

Brush & Magnet Pigs

Ideal for ferrous debris removal and preparing pipelines for inline inspection (ILI).

Batching & Displacement Pigs

Maintain product separation and maximize efficiency in large-volume operations.


Custom Engineered Solutions

Every pipeline is different. We design pigs specific to your:

  • Line size and wall thickness
  • Product type
  • Flow conditions
  • Debris profile
  • Inspection requirements

No guesswork. No off-the-shelf limitations.


Designed to Stay Stable. Built to Perform.

Large-diameter pipelines can quickly expose weaknesses in poorly designed tools.

Our pigs are engineered to:

  • Maintain consistent sealing across long distances
  • Resist tool deformation under high forces
  • Stay centered and stable at higher velocities
  • Provide effective cleaning without compromising inspection readiness

Because when a pig underperforms in a 42" or 48" line, it’s not just inconvenient—it’s expensive.


Faster Turnaround—Even for the Biggest Jobs

Large diameter projects are often on tight schedules. Because we manufacture in-house in Tulsa, we control:

  • Design
  • Engineering
  • Production
  • Quality

That means faster turnaround times—even for fully custom tools—so your project stays on schedule.


Built for ILI Success

If you’re planning an inline inspection run, cleaning isn’t optional—it’s critical.

Our large diameter cleaning pigs are designed to:

  • Remove debris that can interfere with data collection
  • Reduce the risk of tool damage
  • Help ensure accurate, reliable inspection results

We don’t just build pigs—we help you prepare your pipeline for what comes next.


More Than a Vendor—A Partner in Your Operation

What sets Enduro apart isn’t just the tools—it’s the people behind them.

Our team works directly with operators and field crews to:

  • Understand real pipeline conditions
  • Recommend the right cleaning approach
  • Support your project from planning to execution
  • Supply rebuild kits for your pipeline pig to keep operations running smoothly

You’re not ordering a product.
You’re working with a team that’s done this before.


Come See It for Yourself

We believe the best way to understand what we do is to see it firsthand.

Our doors are always open.

We invite customers to visit our Tulsa facility to:

  • Tour our manufacturing operations
  • See how cleaning pigs are designed and built
  • Meet the team behind the tools
  • Learn how we support both large and small diameter projects

Frequently Asked Questions


  • What size pipelines are considered large diameter?

    Typically, pipelines 36 inches and above are considered large diameter, though operational challenges can begin even earlier depending on conditions.

  • Do large diameter pipelines require custom pigs?

    In most cases, yes. Standard designs often don’t provide the sealing, stability, or cleaning performance required for larger lines.

  • How do I choose the right cleaning pig?

    It depends on your pipeline conditions, product, debris type, and project goals. Our team works with you to recommend the right solution.

  • How far in advance should I plan for large diameter pigging?

    The earlier the better—especially for custom tools. That said, our in-house manufacturing allows us to support tight timelines when needed.

  • Can Enduro support both large and small diameter pipelines?

    Yes. Enduro specializes in cleaning pigs for all sizes and configurations. From smaller diameter lines to large diameter pipelines, we design and manufacture tools built around your specific application, operating conditions, and cleaning goals.
