Long and high neck flange: the neck height is higher, which improves the stiffness and bearing capacity of the flange.Compared with butt-welding flange, the welding workload is large, the electrode consumption is high, can not withstand high temperature and high pressure and repeated bending and temperature fluctuations, but the site installation is more convenient, can omit the welding seam patting kneading process, more popular.
