Lap Joint Flanges Manufacture in India

Lap Joint Flanges lack a raised face, making them comparable to other industrial flange types. A lap joint stub end is utilized in conjunction with lap joint flanges. Comparable welding neck flanges are about one-third less expensive initially than a lap joint flange with a stub end. Comparatively speaking, lap joint flanges have a lesser pressure holding capacity, and their assembly’s fatigue life is only one-tenth that of welding neck flanges. Pipe systems that need to be disassembled often for cleaning and inspection typically use the lap joint flange with the stub end assembly. These flanges are not welded or otherwise attached to the pipe; instead, they slide over it. The pressure of the flange on the back of the pipe lap (Stub End) transfers bolting pressure to the gasket.
