Oil tubing coupling/Pipe coupling
are highly demanded in the pipe fitting market. Pipe couplings are fittings that help to extend or terminate pipe runs. These fittings are also used to change pipe size. Couplings extend a run by joining two lengths of pipe. They are known as reduced coupling if they are used to connect pipes of different sizes.
Couplings are also known as repair couplings. These couplings are without stops or ridges and they can be fixed anywhere along the pipe length for preventing leak of any kind.
Some important features of couplings are as follows:
Couplings come in all standard pipe sizes and are available for almost all types of pipe.
Available in several finishes.
Mostly cylindrical in design.
Couplings compensate for axial, lateral and angular shaft misalignment.
Couplings operate in quiet and smooth way.
There is a great degree of torsional stiffness.
There is the right angular transmission of angular motion and torque.
Usually long life.
Easy mounting and dismounting.
Low lateral stiffness etc.
