Lap Joint Flanges

Description

Lap Joint Flanges

The lap flange is having two components, a stub end, and a loose backing flange. The stub end is butt-welded to the pipe, and the backing flange freely moves over the pipe. The backing flange can be of a different material than stub material and normally of carbon steel to save the cost. Lap flange is used where frequent dismantling is required and space is constrained.

• The backing flange can be of a different material than stub material and normally of the carbon steel to save the cost.
• This flange provides better joining due to butt-weld as compared to a socket and threaded type flanges
• Not suitable for small size, Costly components, and fabrication as compared to threaded, slip-on, and socket flange.
• Lap flange provides connection flexibility as you can freely rotate the flange on the pipe. It is used where frequent dismantling is required, and space is constrained.
