Double-ends Socket Welding Couplings ASME B16.11 3000LB
Concept of SW Couplings
Socket pipe fittings are mainly used in petrochemical, medical and health, electric power, aerospace, military, fire protection, metallurgy, shipbuilding, gas, nuclear power, and environmental protection, which require high pressure pipelines, precision size equipment and other various high voltage field.
The socket weld couplingis a pipe connection piece machined by round steel or steel ingot die forging. Its connection form is socket welding (Socket Welding-SW), and the steel pipe is inserted into the socket hole for welding. Therefore, it is called “Socket weld”.
