Threaded Coupling Forged Steel Fittings
Threaded couplings used thread connection to connect two pipes.Threaded coupling is belong to forged steel fittings.The other type of forged fitting is socket weld fittings.All the forged fittings are high pressure pipe fittings.
Threaded coupling means the coupling has threads at one or both ends.It is a commonly used accessory for industrial pipe connections.It could be full coupling and half coupling.Threaded fittings are belong to forged fittings.
Full Coupling: Both ends of the full thread coupling are threaded.
Half Coupling: One end of a half thread coupling is threaded 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
They are widely used in various industries, including chemical processing, petroleum, refining, marine waste treatment, utilities / power generation, industrial equipment, natural gas compression and distribution industries.
