Pig Cleaning & Hydrostatic Testing


This service is now available at our Moffat and Fremont County locations.
Pipeline pigs are devices placed inside a pipe that traverse the pipeline. They are used in hydrostatic testing and pipeline drying, internal cleaning, internal coating, liquid management, batching, and inspection. In hydrostatic testing, the pipeline is filled with water (or other test liquid), removing any trapped air.
The pig is inserted ahead of the fill point, and liquid is pumped in behind the pig to keep the pipe full and force air out. Pigs then remove the test liquid and are used to help dry the pipeline.
