pigging
- noun

- It may be that, given a recorded reduction in original design wall thickness following an intelligent pigging run, an operator decides to reduce the maximum allowable operating pressure of the pipeline such that the risk of overpressure due to corrosion at given areas of a pipeline is minimized.
- smart pigging

However, in earlier days around 30 years ago, many old built pipelines (some of them are still in service) didn't have a pigging structure. These pipelines are really hard to assess and to know their condition, and some of the companies modified the layout and added pig launchers just to assess the integrity of the pipelines.

Etymology
Pigging for pipeline work comes from the tool called a pig that engineers send through a pipe to clean or check it. A helpful way to remember this is that early pigs scraped and 'rooted' through dirt inside pipes like a real pig in mud, and some people also say the name comes from the letters PIG for 'pipeline inspection device'. So, pigging is the act of sending that tool through a pipeline to remove buildup or inspect it.
