Buttweld Stub End | Hallmark Metallica is one of the reputed exporters of Buttweld Stub End

  


Butt Weld Stub End

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.

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.
