Our product recovery system or PIGGING SYSTEM consists of a launcher, a catcher and a pig (one-piece, solid molded urethane projectile). Prior to start-up, the pig is placed in the launcher located in the pipeline and just down stream from the pump. Once the run is completed, air pressure is applied to the pig to push it through the main pipeline, forcing the remaining product to a recovery point at the end of the pipeline. The projectile travels through standard 90° elbows until it reaches the catcher, and then the propulsion.
