Long neck flange is also called long diameter flange, belongs to the American standard flange standard system, is a form of ANSI flange, is a neck butt welding flange expansion form. Flange neck slightly straight tube, the neck height of 229MM or 305MM, flange neck does not need to be processed, according to customer requirements customized beveling. Long neck flanges are frequently used in CLASS series pipe flanges. When small size flanges or pipe flanges below DN50 are combined with pipe body, using long neck flanges can avoid the difficulty of welding caused by the thickness of flange neck wall.
The advantages of long neck flange: the neck height is higher than that of ordinary butt welding flange, so that the stiffness and bearing capacity of the flange are greatly improved. Site site installation is convenient, can omit some processes, such as: weld is easier to handle, can omit weld flaw detection process, in recent years, the use of a rising trend.
