What is Coupling

A pipe coupling plays an important role in connecting the pipe to maintain the integrity of the pipes in the plumbing processes. It is useful for pipe fitting for the plumbing industry. Most plumbing installations require several pipes that need to be joined together. For connecting these cut pipes, couplings are used.

What is Coupling?

A coupling is a very short length of pipe or tube, having a socket or female threads at one or both ends. IKER Coupling allows two pipes or tubes of equal or different sizes to be joined together and make a long pipe. The body of the coupling is made up of the same or similar type of material as that of the pipe it joins. They may be either rigid or flexible depending on the amount of movement of the pipe and also they can be permanent or removable. It can be increased or decreased in the internal diameter to join different sizes of pipes, which can be of T or cross-shaped to form bends.

What are the Different Categories of Coupling?

Couplings can be divided into two different main categories according to their usage.

•Permanent coupling

•Removable coupling

Permanent Coupling:

Permanent couplings are used to create permanent joints between two pipes. They can be joined using soldering or brazing in case of steel or copper pipe materials, or using adhesives in case of PVC pipes. When these couplings are installed correctly, these permanent couplings offer excellent rigidity in sealing characteristics. These are used in the pipes where it doesn’t need any change of pipes in the future.

Removable Coupling:

This type of removable coupling uses several threads which allows them to be screwed into the pipes to join together. It uses a basic pipe section that is larger than any pipes to be joined and cut with an internal thread. The pipe ends are threaded, then these couplings provide excellent sealing by screwing onto both pipes.

How to Select the Right Coupling?

The following are some factors is used in selecting the right coupling material.

•Always select the right coupling type for the correct intended usage.

•Select the right coupling material in order to get excellent performance with the sealing characteristics.

•Choose the right size of the coupling that can be fitted to the torque, space, and pipe size required.

•Select the fastening methods to the coupler between the pipes. It may be of brazing or soldering in steel or copper pipes, and for PVC pipes adhesives are much enough.

Conclusion

Couplings are used to join the two pipes in order to make the pipe longer. From the above, you can clearly understand the basics and types of coupling. Make sure you select the right coupling for your need.
