Sw couplings DN 6-100 6000lb ASME B16.11
Concept of SW Couplings
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”.
The common product categories of socket fittings are: socket cap, socket 45° elbow, socket 90° elbow, socket equal diameter cross, socket reducing cross, socket equal diameter tee, Socket reducing tees, socket pipe clamps, socket unions, etc.
