A weld neck flange has a long, tapered hub that smoothly merges with the pipe. This design of weld neck flange is crucial to provide a smooth transition of stress, reducing the risk of leakage and failure. As the name suggest, the flange is welded to the pipe at its neck, this high strength joint ensure that it is capable of withstanding severe mechanical stress and harsh operating conditions. These flanges are commonly used in high-pressure and high-temperature applications where fluid dynamics are a concern.
