Pig Receiver and Launcher are essential equipment of pipeline
pigging, which is installed on both ends of pipeline to launch or
receive the pigs.
Basic structure: A extension tube is welded to barrel of launcher
to balance front and rear pressure of pig. 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 and to prevent it from impacting the valve spool prior to
the opening of the valve at the end of exit.
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: 3mm 4.Seismic intensity: 7 degree
5.Applicable pipeline contents: crude oil, finished petroleum oil
(gasoline, diesel), natural gas, coal gas, water, and so on.
