Stub End

Stub Ends are used to connect pipes in piping arrangements and are generally manufactured by welding two sub-components. The stub-end shape is formed by rolling dies instead of an outer mold. During this process, the lap roller motion is dependent on the required degree of forming.

Rio Engineering is the leading manufacturer and Exporters of Stub End. There are two types of Stub Ends, Long Stub End, and Short Stub End.
