A stub end is a type of pipe fitting used in various industrial applications to connect pipes or flanges. It is designed to be welded to the pipe or lap joint flange, providing a secure and leak-proof joint.  The stub end itself does not have any threading;  instead, it acts as a sleeve that slips over the pipe or lap joint flange.  This unique design allows for easy and quick disassembly of the joint when needed.
