Steel coupling is a piece of short pipe that is used to connect one pipe with another pipe, scope of application is also more widely, like agriculture, industry, construction and so on. There are socket welding couplings and threaded couplings, they are all High Pressure Forged Fittings. Pressure shall be CLASS3000, CLASS6000, CLASS900. The standard of these products are in compliance with ASME B16.11.
Socket welding coupling
Pipes are put into socket welding hole and welded. Because of this connection, installation cost is reduced.
Threaded coupling, the type of thread is NPT.
For Npt Coupling, the length of thread will be mentioned under the standard ASME B16.11.
