High Neck Flange

High neck flange

Products used in boilers and pressure vessels, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbows, food and other industries

High neck flange refers to the high neck height, which improves the stiffness and bearing capacity of the flange.

High neck flange: Compared with butt welding flange, the welding workload is large, the electrode consumption is high, and it cannot withstand high temperature and high pressure and repeated bending and temperature fluctuations, but it is more convenient to install on site, and the process of weld film flaw detection can be omitted, which is more popular.
