STUB ENDS ANSI B 16.9

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. 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.
Our high quality stub ends (Butt weld fittings) are tested and verified for durability, accuracy and precision. The stub ends are manufactured in all standard dimensions. The stub ends are provided with a standard weld bevel and can be available in squared, flanged, victaulic and threaded ends. We offer stub ends at highly competitive prices.
