Pigging and Decoking Services
Clean Harbors is the only single source, full-service provider to offer comprehensive pigging services and "Smart pig" inspection technology for refinery and plant processes.
Internal buildup of deposits, which decreases throughput and thermal efficiency, is a common problem for refineries and chemical plants. Clean Harbors provides a safe, fast and environmentally friendly approach to cleaning the interior walls of fired heater tubes and pipelines through our pigging and decoking services.
Proprietary Processes and Equipment
The closed loop process uses a high volume, low pressure centrifugal pumping system to propel our patented bi-directional pigs through pipes and coils for cleaning. Closed loop pigging minimizes equipment downtime and is more efficient and less damaging to pipes than steam air decoking. All removed material can be contained for disposal or analysis.

- The world’s largest fleet of twin-pump units, available 24/7
