Pipe unions refer to forged pipe fittings,which are the most common pipe fittings in industry and life.It can be divided into socket union and threaded union. Pipe Union is a type of fitting equipment designed in such a way to unite two pipes which can be detached without causing any deformation to the pipes.The pipe unions make the connection of the pipeline simpler and easier to disassemble and replace,which greatly saves the cost of the pipeline connection.

The pipe unions used in industry are usually made of metal with high pressure resistance.The materials are carbon steel,stainless steel,alloy steel etc.

Three parts of pipe union:
A pipe union consists of three parts – a nut,a female end and a male end. To make an effectively working pipe fitting,both the male and female ends are sealed together with the help of nuts.A female threaded fitting has threads on the inside,while in the male-threaded fitting,the threads are on the outside.As the pairing ends of the union can be interchanged,these pipe fittings can be easily changed in a short span of time.

With the joining of the female and male ends,the nuts are used to provide the necessary pressure to seal the joint.
The parts of the pipe union are normally locked together by at least one radial screw or nut with sized cross section.When severe pulling stress is applied onto the pipe union from the outside, the locking screw breaks and removes the two parts of the union, which in turn separates together with the pipes to which they are attached. Under normal conditions elastically stressed sealing objects ensure maintenance of watertightness between the union parts.

Advantages of pipe union:
The union has high strength and good ductility, which can give full play to the strength and ductility of the steel bar base material.
The connection is convenient, fast and easy to operate.
Inspection is convenient and intuitive.
The straight thread processing of reinforcing bar can be predicted, the sleeve can be manufactured in factory, which does not occupy the construction period, and the processing efficiency is high.
No electricity, no gas, no open fire, no oil leakage, no pollution, no rain or wind, all-weather construction.
It has strong applicability and can be operated flexibly in narrow and narrow sites where steel bars are arranged densely.
Horizontal, vertical steel bars of the same or different diameters can be connected.
