Why use the lap joint flange?


Lap joint flange can swivel around the stub end and pipe lining. When the piping system is assemble and disassemble frequently, it is better to use a Lap joint flange. It means the flange can work even the two flanges bolt holes are misalignment .


In a corrosive situation, the flange joints need to be exchange very soon. To a lap joint flange, only the stub end is touch with the pipe and fluid , the backing flange no need to touch it . It means you could only replace the stub end , no need to replace the backing flange , so the lap joint flange can decrease the cost of the piping systems.


The backing flange and the stub end is separated , so we can use two different materials for the two pieces. it can work for more complicated application.
