Stainless Steel Socket Weld Couplings ASME B16.11 Forged Fittings

Stainless steel socket weld couplings can be called simply as SS SW Couplings.ASME B16.11 forged fittings are the most used fittings all over the word because the American Standard are famous.Socket welded fittings can be provided 3000LB,6000LB,9000LB.

Stainless steel socket weld (SW) couplings  are belong to ASME B16.11 forged fittings.Forged fittings are including both socket weld (SW) fittings and threaded (THD) fittings.Both of SW fittings and THD fittings are high presssure pipe fittings.

 

Two Types of SW Couplings:

Full Coupling:Both ends of the couplings can socketed with the pipes and then welded with the pipes to achieve a strong connection.

Half Coupling:One end of the couplings use socket connection, and the other end use welded connection to connect to the pipes.

Both types of couplings are high pressure pipe couplings can be manufactured as CL3000, CL6000, CL9000 to serve in different applications.

Shapes:

Straight: It is a kind of pipe coupling with the same diameter at both ends.Used to connect with pipes and transfer fluids.

Reducing: The two ends of the coupling have different sizes.One more function is reduce the flow in the piping system.
