Pig Launcher ReceiverA Launcher is located at the upstream end of the pipeline to launch the Pig into the pipeline. A Receiver is located at the downstream end of the pipeline to remove the Pig from the pipeline.

What are the Pig launcher and receiver?

Pigging in pipeline maintenance is the practice of using a pipeline inspector or "pigger" to perform various operations on a pipeline without stopping the flow of product in the pipeline. Pigs are named for the squealing sound they make as they move through a pipe. These operations include but are not limited to, pipe cleaning and inspection. This is accomplished by inserting the pipe cleaner into the pipe cleaner transmitter (the funnel-shaped Y-shaped portion of the pipe). The launcher is then closed and the pressure of the product in the pipe is used to push it down the pipe until it reaches the receiving trap - the "pig catcher".

If the pipeline contains a butterfly valve, the pipeline cannot be cleared. Ball valves do not create any problems because the inner diameter of the ball can be specified to be the same as the inner diameter of the pipe.

The main function of a Pig Launcher and Receiver is to allow operators to launch and receive pipeline pigs without disrupting line contents or interrupting and shutting down pipeline operations. Often referred to as Pig Traps, Pig Launchers and Receivers are available in a wide variety of styles and customizable configurations dependent upon the application and customer requirements.
