Decoking and Pigging Services

Features of Clean Harbors Decoking and Pigging Services include:

  • Largest fleet of twin pump units, each equipped with flow rate, pressure, and acoustic tracking systems to control pig runs and detect and target problem areas.  Multiple coils or lines can be cleaned independently with each unit.
  • Experienced operators assigned to each project.
  • Pig selection carefully performed based on tube metallurgy.  Our patented pig designs protect the internal pipe surface from damage, and pigs are custom manufactured in-house under strict quality control specifications.
  • Environmentally friendly compared to conventional methods and all of the removed material is contained for safe disposal and analysis.  No chemicals are used during this process and by utilizing Clean Harbors specifically designed filter press units, in excess of 90% of the water is recycled.
  • Each unit is operated from a climate controlled cab and is equipped for immediate shutdown, optimizing operator safety.
  • Closed loop pigging minimizes your downtime and allows for concurrent maintenance to be performed in the same area.

Specialty Decoking & Pigging: Maximizing Thermal Efficiency

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 Small Diameter Ultrasonic Smart Pigs

Advanced inspection for small diameter pipelines and fired heater tubes

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
