Stub Ends
Our organization is engaged in offering an extensive range of Stub Ends, which is sourced from authentic vendors. These stub ends are available in different lengths and can also be installed with ease. Our range of Stub Ends is an economical way of flanging in low pressure.

What are they?

Stub Ends are fittings used in place of welded flanges where rotating back up flanges are desired.

They are also called Lap Joints and Vanstone Flared Laps.

How do they work?

A rotating back up flange seats itself against the back surface of the Stub End. When bolts are added, the clamping action of the bolts presses the rotating back up flange against the back of the Stub End. The gasket surface of the Stub End then presses against a gasket and another gasket surface providing joints like standard flange joints. The seal is made by the gasket surface of the stub end alone, the flange only provides the clamping pressure on the joint.

Why?

Since Stub Ends are made from material compatible with the designed piping system, back up flanges do not have to be made from the same material. The flange can be made from less expensive material because it never comes in contact with the process fluid.

Types

Stub Ends are typically manufactured by two methods. Type A & B Stub Ends are made similar to forged fittings such as Elbows and Flanges. Type C Stub Ends are made by forming pipe to the desired dimensions.

Stub Ends are available in two standard lengths, MSS and ANSI.

Stub Ends are normally provided with a standard weld bevel
