Pipe fittings are components that connect pipes to each other. In addition to simply extending pipes, pipe fittings are used to change the route of pipes, branch or merge pipes, enlarge or shrink the diameter of pipes, and seal the ends of pipes.
Some pipe fittings are removable after connection, while others are fixed once connected. However, it is encouraged to install some removable pipe fittings because if they are all fixed, it will be difficult to repair them in the event of a piping failure.
Pipe fittings come in a variety of shapes, materials, and connection methods. Appropriate pipe fittings must be selected according to the intended use of the fitting and the type and material of the piping.
Pipe fittings are used to connect pipes that transport gases and liquids. Therefore, all facilities that use piping always require pipe fittings.
Pipe fittings are used in a wide range of fields, including water supply facilities, hot water supply facilities, drainage pipes, ventilation pipes, gas pipes, fire prevention pipes, cold and hot water circulation systems for air conditioning, agricultural water pipes, and chemical plant pipes.
In addition to fluid piping, pipe fittings are also used for cable protection in the electric power and telecommunications fields and are expected to improve the efficiency of construction work as the use of utility poles is promoted in the future.
Pipe fittings come in a variety of shapes and connection methods.
The shapes of pipe fittings vary depending on their applications. The main types of pipe fittings are as follows.
Pipe fittings can be connected by threading, welding, or flanging.
When selecting a pipe fitting, in addition to the shape and connection method described above, the material and size (pipe diameter) must also be taken into consideration to select an appropriate pipe fitting.
