SW Full Coupling ASME B16.11 Pipe Fittings
SW full coupling is used to connect two pipes.Couplings can be full coupling and half coupling.ASME B16.11 pipe fittings are forged fittings including SW fittings and THD fittings.Socket weld fittings have many pressures:CL3000,CL6000,CL9000.
SW (socket weld) full coupling has both ends to socketed with pipes.ASME B16.11 pipe fittings are forged fittings including socket weld fittings and threaded fittings.
SW coupling means the coupling can socket with pipes by one or both ends. It is a commonly used accessory for industrial pipe connections.
Socket Weld(SW) fittings are high pressure fittings which are used in the pipe system,and only in conjunction with ASME pipes.SW fittings have same ranges of size(1/8”-4”) and pressures(2000lb,3000lb,6000lb，9000lb).
Full Coupling: Both ends of coupling can socket with pipes.
Half Coupling: One end of a half coupling is socketed and the other end is welded.
Straight: It is a kind of pipe coupling with the same diameter at both ends.
Reducing: The two ends of the coupling have different sizes
