Pigging is a mechanical cleaning approach involving specialized “pigs” that propel through the pipeline, effectively removing water, debris and other contaminants. Pipeline pigs got their name from how earlier versions of the device would squeal as they traveled through piping systems.
A pipeline “pig” also serves as an acronym for pipeline inspection gauge or pipeline intervention gauge. These specialized tools are inserted into the pipeline and propelled by fluid or gas, performing a variety of functions based on their design, including cleaning, inspection and liquid separation.
Pigging is crucial in maintaining the efficiency, safety and longevity of high-scale industrial projects. Over time, pipelines can accumulate debris, corrosion and contaminants that decrease performance and lead to costly downtime. Pigging ensures piping remains clean, blockage-free and structurally sound. By preventing corrosion and detecting defects early, pigging contributes to uninterrupted operations and extends the life of pipelines.
At B&W Energy Services, we understand that every project has unique needs, and we tailor our line pigging services to accomplish your specific goals. Different piping applications and contamination levels require specific pipeline pig types, and our team of experts will work closely with you to determine the most suitable line pigging solution for your project.
B&W’s experienced engineers will develop a comprehensive plan, including selecting the appropriate pigs, the pigs’ design and the execution of the pigging process.

| Criteria | Pigging | Steam Blowing | Air Blowing |
|---|---|---|---|
| Cleaning method | Mechanical device (pig) moves through pipe | High-velocity steam | Compressed air |
| Best for | Long straight runs, debris stuck to pipe walls | Large systems, debris + moisture removal | Smaller lines or multiple lines, water & light debris removal |
| Typical contaminants removed | Debris, scale, wax, stubborn deposits | Debris, welding scale, water | Loose water, sand, light debris |
| System condition | Dry or semi-dry | Wet, after hydrotesting | Wet, after hydrotesting |
| Access required | Launcher & receiver points | Direct connection to steam system | Connection to air compressors |
| Risk level | Low to medium (mechanical) | Low (pressure & heat risk) | Longer due to circulation |
| When to choose | If physical scraping/contact is needed | For large systems where steam is available | Quick removal of light debris or water |
Pigging improves pipeline maintenance by preventing buildup, reducing corrosion risk and restoring optimal flow conditions.
Regular pigging removes contaminants that degrade system performance and lead to unplanned downtime. B&W integrates pigging into maintenance programs to support long-term reliability, extend equipment life and minimize emergency interventions.
Pigging safety requires controlled pressures, proper isolation, trained personnel and engineered procedures.
B&W conducts hazard assessments, uses pressure-rated equipment and follows strict operational protocols to prevent overpressurization, pig blockages or personnel exposure. Safety planning is integrated into every pigging project to protect both systems and site personnel.
