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. 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. In other words, the pipe unions can disjoint two
pipes very easily. They are widely demanded in the pipe fitting market.
Important features that buyers should look
- Easy to install
- Corrosion resistance
Three parts of pipe union:
- Stainless steel
- Cast iron
- Rubber etc.
- A nut
- A female end
- A male end
With the joining of the female and male ends, the nuts are used to
provide the necessary pressure to seal the joint.
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.
Types of pipe unions:
There are two basic types of pipe unions:
- Ground Joint Union
- Flange Union
The difference between the two is that the former consists of three
pieces while the latter two pieces.
Applications of pipe unions:
Pipe unions are used in various municipal and industrial applications
like as follows:
- Fire protection
- Process piping system
- Water and wastewater etc.
Advantages of pipe union:
There are various advantages of pipe unions like:
- To provide a leak-proof disconnection point in any piping system.
- Used for inserting metering and regulating devices into any
- Can connect piping system to vessels.
- Can join two pipes of different size together.
- Can easily remove the join between two pipes.
- Easy to install.
