What Is a Pipe Coupling?

As the name suggests, a buttweld pipe coupling is used to connect two different pipes or hoses. It is very common type of fittings used in day to day applications. Stainless steel pipe couplings are the most used types. These butt weld fittings are used in all the applications wherever pipes are involved.
