Pig launcher and pig receiver
Pig Receiver &Launcher are essential parts of pigging equipment, which is installed on both ends of pipeline to launch or receive the pig. It consists of quick-opened closure, barrel, reducer, support saddle, etc. It could be divided into vertical and horizontal types. The vertical type is mainly used to launch and receive pipeline cleaning pig, and horizontal is for filter and the like.

Technical Parameters:
1.Design Pressure: PN1.0-42.0Mpa
2.Test pressure: hydraulic pressure is 1.5 times of the design pressure and gas leakage test pressure is the same as the design pressure.
3.Corrosion allowable: 2mm
4.Seismic intensity: 7 degree
5.Applicable medium: crude oil, finished petroleum oil (gasoline, diesel), natural gas, coal gas, water.

Basic structure and parameters:
A extension tube is welded to barrel of launcher to balance front and back pressure of pig when the pig is ready to launch. When the pig is ready to be launched, pressure applied upon the pig, which will run towards the spool of check valve or ball valve. Open the valve at this moment will certainly damage the valve spool and cause leakage of valve. The function of balance extension tube is to keep the pig balance in the launcher prior to the opening of the valve at the end of exit to prevent it from impacting the valve spool.
