Pigs, pipe cleaning

Jeff Griffin, Senior Editor

A new breed of pipeline “pig” has arrived in the United States.

“Pigging” to clean pipelines is an accepted procedure used by utility pipeline owners. The process is relatively simple: a device (pig) is inserted into a pipe where pressure forces it through the pipe, scraping the inside sidewalls and carrying debris to an exit point out of the pipe. A variety of pig designs are available.
