Quick Opening Closure ASME U Stamp Pig Launcher Receiver

  • Description
Product Detail

1.0 Definition 

The pig launcher/receiver (the “launcher/receiver”) is the equipment that can receive and launch pig under pressure in the pipeline of liquid and gas. It is installed at both ends of the pipeline or the interim pressure regulating valve room of pipeline, as an important device to clean, remove residues and rust, scrape wax and apply coating. Due to the pressurized working condition, the design, manufacture, test and acceptance are in strict accordance with ANSI B31.4 Liquid Petroleum transportation Piping System.


2.0 Components 

(1) Quick opening closure (4) Inlet and outlet nozzle (7) Reducer (10) Blowdown valve nozzle

(2) Pressure gauge nozzle (5) Safety valve nozzle (8) Sub-cylinder (11) Fore saddle support

(3) Cylinder (6) Vent valve nozzle (9) Rear saddle support


The launcher/receiver is composed of quick opening closure, main cylinder, reducer, sub-cylinder, inlet and outlet nozzle (the launcher as the inlet and the receiver as the outlet), pressure gauge nozzle, blowdown valve nozzle, vent valve nozzle, safety valve nozzle, saddle support (the intelligent pig launcher/receiver have balance port). The accessories that connect the launcher/receiver consist of pressure gauge, blowdown valve, vent valve, ball-passing indicator, safety valve as well as the flange, bolt, nut and pad that match with various interfaces. As required by the customers, the sliding filter bear basket, rotating crane and cathodic protection devices can be provided additionally. 


3.0 Technical Performance 

In general, the pig launcher/receiver are installed horizontally. For exceptional circumstances such as slope, well bottom and underground, the slant or vertical installation can be adopted upon considering safe conditions. The quick opening closure at the end is capable of secondary pressure relief, so that the pressure difference between the inside and outside maintains to be zero to ensure safe operation.         


4.0 Norms and Standards

The design, manufacture, test and acceptance of pig receiver meet the following norms and standards of the latest edition. If there are more than one standard, regulation and norm that meet the same requirement, the most stringent one and ISO9001 quality system shall be followed.
