A Pipe Coupling, used in piping or plumbing, is a very short length of pipe or tube with either socket or female pipe threads at one or both ends that allows two pipes or tubes of equal or different sizes to be joined together. Couplings are pipe fittings that help to extend or terminate pipe runs. These fittings are also used to change pipe size. It’s also used to repair a broken or leaking pipe.
The body of a pipe coupling is typically made of either the same or similar materials as that of the pipes it joins. They may be rigid or flexible depending on the amount of movement the pipe is subjected to and may also be permanent or removable. A pipe coupling can be increased or reduced in internal diameter to join pipes of different sizes, be T or cross shaped to join more than two pipes, or angled to form bends. Pipe couplings may also include peripheral features or equipment such as inspection openings, flow meters, or valves.
Simple Installation :-
Most pipe installations require several lengths of pipe to be joined together or cut to facilitate changes in direction and crossing of obstacles. This requires a fairly quick method of connecting the pipe sections while maintaining the integrity of the pipes in the process. A pipe coupling is a pipe fitting used to join two or more pipes in such a way that continuity is maintained between them.
