Class 3000 SW (socket weld) coupling is the most commonly used pressure fitting,there is also class 6000 pressure.Stainless steel fittings can be used over 50 years as its high corrosion resistance.

 

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).

 

Types:

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.

 

Shapes:

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
