Long Weld Neck Flange LWN

Long weld neck flanges have a relatively high neck, which improves the rigidity and load-bearing capacity of the flange. Compared with welding neck flanges, they involve a larger amount of welding work and higher electrode consumption, and cannot withstand high temperatures, high pressures, repeated bending, or temperature fluctuations. However, they are more convenient for on-site installation and can eliminate the process of weld grinding and damage, making them relatively popular.
