Pig Launcher & Receiver Device

Products overview: Pig receiver &launcher device, referred to as pig receiver &launcher, belongs to the pipeline accessories, widely used in all kinds of medium pipeline. In general, the main installation ends for sending and receiving the pig, in the pipeline through ball production line and the production of Saul, and Saul oil, qing wax removal. According to user requirements, the device can design for two-way use. Its main structure by the barrel, fast-opening blind and relevant connected component. Import. Product structure: 1.Rapid opening blind flange 2.Barometer connecting tube 3.Relief valve connecting tube 4.Fluid outlet tube 5.Barrel body 6.Relief valve connecting tube 7.Variable diameter tube 8.Extension tube 9.Rear support 10.Contaminant discharge tube 11.Front support Technical Parameters: 1.Design Pressure: PN1.6-16.0Mpa 2.Test pressure: water pressure is 1.5 times of the design pressure and air-tight test pressure is the same as the design pressure. 3.Corrosion allowable: 2mm-3mm 4.Seismic intensity: 8 deg 5.Applicable medium: crude oil, finished petroleum oil (gasoline, diesel), gas, water. Design and manufacturing basis: GB150-1998 Steel Pressure Vessel Structure features: A extension tube is added to ball launching barrel to balance initial pressures before and after the pipe cleaner. When initiating the ball, owing to the pressure applied upon the cleaner which, in turn, is moving towards the check valve (or globe valve) core,the opening at this moment will certainly damage the valve core to cause valve breaking and inability to seal. The balance extension tube functions to retain balanced pressure in front and at the back of the cleaner prior to the opening of the valve to prevent it from impacting the valve core. Install form: 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.
