Weld Neck Flange

Neck flange is one of the types of flanges that are known by this name because of having a conical neck. This flange has a conical neck whose radius at the end is equal to the diameter of the pipe and is welded to it. The presence of this neck strengthens the tolerance of the flange. This type of flange is suitable for bearing high pressures and temperatures below zero, as well as fluctuating and vibrating loads.
