Why Custom Cleaning Pig Designs Matter
Standard cleaning pigs work well for many pipeline applications. But when a pipeline has unusual geometry, changing diameters, heavy or hardened deposits, difficult bends, or unique operating requirements, an off-the-shelf configuration may not be enough.
Enduro Pipeline Services designs and manufactures custom pipeline cleaning pigs for applications where standard configurations reach their limits. Our team evaluates the pipeline conditions, the material that needs to be removed, and the operational objective to develop a pig configuration for the specific challenge.
From tandem cleaning pig trains and dual-diameter designs to specialty brush configurations and the Enduro Hammer Wheel Pig, our custom builds are designed, manufactured, assembled, and tested in Tulsa, Oklahoma.
Custom Pig Design Starts With the Pipeline Problem
A custom cleaning pig should not begin with a standard configuration and a list of optional components. It should begin with understanding the pipeline and the objective of the run.
Enduro's cleaning pig team evaluates factors such as:
- Pipeline diameter and internal diameter changes
- Bend radius and pipeline geometry
- Launcher and receiver limitations
- Type, hardness, and volume of debris
- Paraffin, scale, black powder, or construction debris
- Sealing and bypass requirements
- Previous pigging results
- Operating conditions
- Cleaning, batching, displacement, or pre-ILI objectives
Based on those conditions, the design may incorporate specialized cup or disc arrangements, brushes, magnets, scraping elements, studded components, tandem configurations, flexible connections, or other application-specific features.
The objective is not to make a standard pig more complicated. It is to build the right tool for the pipeline problem.
Did You Know?
Some of Enduro’s most specialized cleaning pig designs began with a specific problem in a specific pipeline. The Hammer Wheel Pig was originally developed to remove hard-packed calcium carbonate from an 18" pipeline. When a 30" line later presented a similar challenge, the concept was adapted to meet the new pipeline conditions.

The Hammer Wheel Pig was custom-designed and manufactured for a pipeline experiencing significant hard deposit buildup on the pipe wall. Enduro worked closely with the customer throughout the design process to develop a pig capable of addressing the specific cleaning challenge and delivering the performance required for the application.
Following the successful run, the pig was retrieved in good condition, demonstrating both the design's durability and its effectiveness in the field. The cleaning operation removed approximately 50 gallons of hardened debris from the pipeline—material that had resisted the customer's previous pigging efforts.
This successful project highlights the value of collaboration between Enduro and our customers, combining application-specific engineering with proven manufacturing to solve complex pipeline-cleaning challenges and restore pipeline efficiency.

The Hammer Wheel Pig: When Conventional Cleaning Reaches Its Limits
The Enduro Hammer Wheel Pig was developed to solve a specific heavy-debris cleaning challenge.
The original design was created for an 18" pipeline containing hard-packed calcium carbonate that conventional cleaning configurations were unable to remove effectively. The pig uses spring-loaded wheel assemblies with tungsten carbide cleaning elements designed to aggressively work hardened deposits from the pipe wall while the pig travels through the line.
The original application produced significant debris recovery. When a 30" natural gas pipeline later presented a similar cleaning challenge, Enduro adapted the Hammer Wheel Pig concept to the larger pipeline and its specific operating requirements.
This is what custom pig design means at Enduro: understand the problem, engineer the cleaning action, build the tool, evaluate the results, and adapt proven concepts when new pipeline challenges arise.
The 30" ADV-4D-2CC-HW is an aggressive, heavy-duty cleaning pig specifically designed to remove hard, adhered debris and scale from pipeline walls. Its robust construction and high-performance cleaning components allow it to tackle stubborn deposits that conventional cleaning pigs often cannot remove, making it an ideal solution for restoring pipeline cleanliness and improving operational efficiency in challenging natural gas pipeline applications.
We first developed the Enduro Hammer Wheel Pig several years ago to remove hard-packed calcium carbonate from an 18" pipeline, where it packed the receiver full of debris. When a 30" pipeline presented a similar challenge, it only made sense to put the Hammer Wheel Pig back to work.
Once again, it exceeded expectations, proving that when conventional cleaning pigs reach their limits, innovative solutions deliver results.

Technical Insight
Custom Doesn't Mean Starting From Scratch
Many operators assume a custom cleaning pig requires designing an entirely new tool. In reality, some of the most effective solutions come from modifying proven designs to better match the application.
Changes to cup geometry, disc spacing, brush placement, magnets, bypass, or sealing components can significantly improve cleaning performance without requiring a completely new design.
The goal isn't to build something different—it's to build something that solves the specific challenge inside the pipeline.
When Does a Pipeline Need a Custom Cleaning Pig?
A custom cleaning pig may be considered when pipeline conditions or cleaning objectives cannot be adequately addressed with a standard configuration.
Challenging Pipeline Geometry
Diameter transitions, multiple internal diameters, tight bends, unusual fittings, or launcher and receiver limitations may require specialized pig geometry and sealing configurations.
Heavy or Hardened Deposits
Paraffin, mineral scale, hardened deposits, construction debris, and other difficult contaminants may require more aggressive or specialized cleaning elements.
Specialized Cleaning Requirements
Some applications require a specific combination of brushes, magnets, scraping components, studded cups, or other cleaning elements based on the material being removed.
Multiple Objectives in a Single Program
Cleaning programs may involve debris removal, product separation, liquid displacement, gauging, or preparation for inline inspection. Pig configurations can be developed around the operational objective and the conditions of the line.
Previous Cleaning Runs Have Reached Their Limit
- When conventional cleaning pigs continue to return without achieving the required cleaning result, the debris recovered and previous run history can help guide the design of a more specialized cleaning approach.
