Long neck flange

A tall neck flange is a flange with a higher neck height.

Long neck flange: The higher neck height improves the rigidity and load-bearing capacity of the flange. Compared to焊接flange, it requires more welding work and higher welding rod consumption, and is not resistant to high temperature and pressure, repeated bending, and temperature fluctuations. However, it is more convenient for on-site installation, can omit the process of seam tapping damage, and is well-received.

Manufacturing Process: Whole forging, forging and pressing, etc.

Processing Methods: High-precision CNC lathe turning, fine turning on conventional lathes, argon arc welding, etc.

Application Range: Boiler pressure vessels, oil, chemical industry, shipbuilding, metallurgy, machinery, food and other industries
