SW Half Coupling ASTM A182 F304
SW half coupling is a type of socket weld coupling,the other type is full coupling.ASTM A182 F304 forged fittings are stinless steel pipe fittings used in many corrosive environments.Stainless steel pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.
SW half coupling is one type of SW couplings,the other one type is full coupling,ASTM A182 F304 is the most used grade in stainless steel.
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
