Carbon Steel Lap Joint Flanges are pipe fittings used in conjunction with a stub end to form a flange connection. They are ideal where frequent dismantling, alignment flexibility, or ease of maintenance is needed. Unlike weld-neck or slip-on flanges, the lap joint flange does not weld directly to the pipe — instead, the pipe is welded to the stub end, and the flange itself “laps” over it.
