High neck flange

High neck flange: The height of the neck is higher, the rigidity bearing capacity of the flange are improved. Compared with butt welding flanges, the welding workload is large, the welding rod consumption is high, can withstand high temperature pressure repeated bending temperature fluctuations, but the installation is more convenient on the spot, the process of welding film inspection can be omitted, which is more popular.
