Threaded Full Coupling Forged Pipe Fittings Dimension

Threaded couplings could be divide into full coupling (both ends threaded) and half coupling(one end threaded,the other end welded).Forged pipe fittings dimensions are all in small size,1/8″-4″.

Rated 4.8/5 based on 488 customer reviews

Threaded full coupling is one type of theaded coupling,the other type is half coupling.Full coupling use thread both ends to connect with pipes,while half coupling use one end threaded,the other end welded to connect with pipes.Threaded couplings are forged pipe fittings used in piping systems to achieve the connection of the pipes.Customers could choose these two types of couplings for different demand.


Forged pipe fittings demension range is 1/8″(DN6)-4″(DN100).The pressures of couplings to choose are CL3000/CL6000.



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.
