Decoking and Pigging Services


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.
