Lap joint stub end
Lap joint pipe slide directly over the pipe and are most commonly used with stub end fittings. A pipe is usually welded to the stub end and the lap joint pipe is free to rotate around the stub end. The benefit of this is that there will not be any issues with bolt hole alignment. Lap joint pipe flanges are often used for applications that require frequent dismantling.
