B16.9 Factory-Made Wrought Buttwelding Fittings

Stub End standard fittings are specified under teh B16.9 standard. Used in conjunction with the lap joint flange the stub end is welded to the pipe leaving the flange to move freely on the stub end.

The stub end and flange combination typically has a lower pricing than other flanges but also has the advantage of a simpler fitting.
