What is a Long Weld Neck Flange?

Long weld neck flange (LWN flange) is also call integral flange it means a welding neck flange has a very long neck. Commonly, the welding neck flange has a tapered neck and a bevel end which is going to butt welding with the matching pipe. But the long weld neck flange has a straight short pipe as the neck of a long weld neck flange. Long weld neck flange (LWN flange), is used for high pressure situations, integral hub weld neck flanges are used and for very high pressure cases Long Welding Neck flanges are preferred.

Typically, the long weld-neck flange is the anchors for water-mains or sources of gas being pumped into a larger network of pipes, such as those in a factory or in an apartment building. Long weld-neck flanges also are used in situations expansion bends or changes the pipe because of the high pressure.

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flange joints are made by bolting together two flanges with a gasket between them to provide a seal. Flanges are commonly used to connect valves into pipework making it easier for removal and maintenance. There are many common flange standards and flanges within the same standard can either be flat (commonly cast iron, ductile iron) or raised face (commonly cast steel and stainless steel).
