A stub end is butt-welded to the pipe and used with a lap-joint flange that can rotate for bolt alignment. HuaboPipe supplies stainless stub ends to order, DN15–DN3000. Long or short pattern follows the drawing.

How to choose

Use stub end + lap-joint flange when joints are opened often, bolt holes must rotate, or you want a carbon-steel flange with a stainless wetted stub. Do not confuse it with a socket-weld flange.
