Overview
Welding neck flanges mainly have higher necks, which improves the rigidity and bearing capacity of the flanges. The purpose is to transfer the pressure of the pipeline, thereby reducing the damage to the flange, and is suitable for occasions with high pressure and temperature. The main production processes by our company are all forged, Flange density, the possibility of leakage is small , Welding neck flange is more convenient for on-site installation, and can omit the process of welding and scratching.

Application
1.Preferred for high-pressure, subzero or elevated temperature.
2.Hub is tapered and bored to match pipe’s inside diameter so flow is not restricted, preventing turbulence and reducing erosion.
3.Easily radiographed and provides excellent stress distribution.
Advantage
1.Butt welded flange has the characteristics of easy deformation ,good sealing.
2. It has corresponding rigidity and elasticity.
3.The distance between the weld and the joint surface is large, and the joint surface will not be deformed because of the welding temperature, so it is widely used in the welding of pipelines.
