Threaded Union

We are manufacturer of threaded pipe union and supplies class 3000, 6000, 9000 in kinds of materials such as carbon steel, stainless steel, alloy steel.

Pipe union is a forged fitting that designed for unite two pipes which can be detached without causing any deformation to the pipes. Any kind of small diameter piping connections requiring a positive seal and easy assembly as well as disassembly are made with the help of pipe union. Three parts of steel pipe union: A nut, a female end, a male end.

Threaded Coupling VS Union

Threaded coupling and union are both used to connect pipes with threaded ends. Generally speaking, a union consists of three pieces or more, a coupling is a single piece, the union has a center nut that connects the two halves of the union together. As some connections between two sections of piping require occasional disconnections, unions are specified at those locations rather than couplings, which aren’t meant to be disassembled.
