Long Welding Neck Flange Wooden Case Stainless Steel Welsure Class

The remarkable feature of long diameter flanges is that they have a long neck, compared with ordinary flanges, this slender neck is like a bridge, connecting the flange with the pipeline. The existence of the neck not only makes the flange more slender in appearance, but more importantly, it brings many advantages for pipeline connection in function. In high-pressure working conditions, it can effectively disperse the pressure, the huge pressure borne by the pipeline along the neck of the uniform conduction to the flange, greatly reducing the risk of stress concentration, to prevent cracks, deformation and other problems caused by excessive local pressure, as for the pipeline system put on a layer of sturdy “protective clothing”.
