Bi-directional pigs are used in pipeline construction for hydrostatic testing or water displacement, as well as removal of debris and product separation. These pigs have excellent sealing qualities, and their bi-directional design allows the pig to run in either direction in the pipeline.
These pigs can also be used as a cleaning pig or batching pig. Standard discs are urethane, however neoprene or nitrile discs are available.
