Introduction of high neck flange

 High neck flange: the neck height is high, which improves the rigidity and bearing capacity of the flange. Compared with the butt welding flange, the welding workload is large, the consumption of welding rod is high, and it can not withstand high temperature and high pressure, repeated bending and temperature fluctuation, but the on-site installation is more convenient, and the process of weld film detection can be omitted, which is more popular.
