Product Description
Haokun's series of Long Welding Neck flange, also known as long diameter flange, belongs to the American standard flange standard system. It is a form of ANSI flange and an extended form of neck butt welding flange. The flange neck is slightly straight cylindrical, and the neck height is 229mm or 305mm. The flange neck does not need to be processed. The groove can be customized according to the requirements of relevant standards hg20615-2009 or the requirements of customers. Long Welding Neck flange is frequently used in class series pipe flanges. When small-size flanges or pipe flanges below DN50 are matched with the pipe body, the use of a Long Welding Neck flange can avoid the difficulty of welding caused by the thin wall thickness of the flange neck.
