Pig Launcher & Receiver are important parts of pigging equipment, which is installed on both ends of pipeline to launch or receive the pig. It mainly consists of Quick Opening Closure, barrel, reducer, and saddle support.

Classify the Launcher & Receiver by usage:

• Model-A and Model-B are used to launch & receive general pigs.
• Model-C is used to launch and receive intelligent pigs

Classify the Launcher & Receiver by mounted form: Vertical, Horizontal.

The installation of pig Launcher & Receiver is divided into above ground installation and underground installation. As silo is required and it is not convenient for receiver and launcher installation and pig disassembly, underground installation is not adopted now.

For above ground installation, the Launcher & Receiver shall be horizontal, which center is about 1m high from ground, and shall be connected to underground pipe by nozzle stub and bend but not skewed crossing connection. For connection between Launcher & Receiver and pipe refer to pigging operation flow diagram.

Pig Launcher & Receiver shall be horizontal, and the diameter of pig valves shall be equal to the inner diameter of the pipe cleaned. Pig inlet & outlet and oil (air or water) inlet shall be connected respectively to the main pipe by valves. On top of one of the fast-opening ends that closed to the pig Launcher & Receiver shall assemble vent valve, safety valve and pressure gauge, and at the bottom shall assemble drain valve, sideway inlet and vent valve to take out medium from the main pipe as the power of forcing pig and conveyance medium.
