Abstract: A pigging system has an apparatus for launching one or more pigs into a process flow. The apparatus has a housing with a chamber, an inlet, and an outlet. The inlet receives the one or more pigs into the chamber and is sealable. The outlet is in sealed communication with the process flow and passes the one or more pigs out of the chamber to the process flow. A portion of the chamber is in communication with the process flow. A guide disposed in the chamber guides the one or more pigs in the chamber, and an actuator mechanically feeds the one or more pigs guided by the guide to the outlet.
