Alloy steel WN flanges joints to piping system by butt welded. The structure of flanges can transfer pressure from the WN flanges to the pipe itself, reducing high stress concentration at the base of the hub of WN flanges. WN flanges are widely used for high pressure pipe. The inside diameter of WN flanges is equivalent to the inside diameter of pipe.
