Pigging in the context of pipelines refers to the practice of using devices known as pigs to perform various maintenance operations on a pipeline. This is done without stopping the flow of the product in the pipeline.These operations include but are not limited to cleaning and inspecting the pipeline.This is accomplished by inserting the pig into a 'pig launcher' (or 'launching station') - an oversized section in the pipeline, reducing to the normal diameter.igging systems are designed so that the pig is loaded into the launcher, which is pressured up to launch the pig into the pipeline through a kicker line. In some cases, the pig is removed from the pipeline via the receiver at the end of each run.
