Threaded coupling is belong to forged steel pipe fittings.Threaded coupling means the coupling has threads at one or both ends. It is a commonly used accessory for industrial pipe connections.
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.
