Clean Harbors Decoking and Pigging Services provides a safe and environmentally friendly approach to the removal of pipe deposits. The closed loop pigging process uses a high volume, low pressure water pumping system to propel our patented bi-directional pigs through pipes and coils to effect cleaning. Pigging removes all deposits left on the tube wall, improving thermal efficacy and extending run lengths.
The operation is safely controlled from the unit’s control room where flow rates and pressures are closely monitored. Progressively larger pigs are run until all of the deposits are completely removed, and no hazardous chemicals are used during the pigging process.
Clean Harbors’ smart pig is a major advance over manual, visual spot checks of a few accessible points. We offer comprehensive, real-time inspections for previously inaccessible areas and give our clients the ability to inspect the mechanical integrity of every inch of their small diameter pipes and tubes.
The untethered ultrasonic smart pigs inspect fired heater tubes and small diameter pipelines. Clean Harbors has miniaturized and advanced a technology that was previously available only for larger diameter pipelines or had limited data storage capabilities. The new technology supports petroleum, refinery, chemical, paper and other process manufacturing operations. Learn more »
