How It Works: Pipeline Pigging | Schlumberger
How It Works: Pipeline Pigging | Schlumberger

A pipeline inspection gauge, commonly referred to as a pig, is a device used to clean and inspect pipeline. The term originates from the initial pig devices, which were bundles of straw wrapped with wire or leather that were forced down the pipeline, resulting in a squealing sound. The term “pipeline inspection gauge” is a backronym and helps to ...
