Concept of  WN flanges

It is an indispensable part of piping design, pipe fittings and valves, and also an essential component in equipment and equipment parts (such as manholes, sight glass liquid level gauges, etc.). Butt welding flange generally refers to a flange with a neck and a round pipe transition, which is connected to the pipe by butt welding. The distance between the welding port and the joint surface is large, and the joint surface will not be deformed due to the welding temperature, so it is currently widely used in the welding of pipelines.
