    What is a DIN 2573&2527&2631 PN6 Flange?

    Welding neck flange is usually called “ high pivot ” flange. The aim is to transfer pressure in the pipeline, thereby reducing high stress concentration in the flange base. Welding neck flange is the best design to weld the flanges that have structural value. But the price is relatively high, because the production process is complex.

    Advantages of the DIN 2573&2527&2631 PN6 Flange:
    1.Stable performance
    The welding flange has the corresponding rigidity and elasticity requirements and a reasonable welding thinning transition, the distance between the welding joint surface is large, and the joint surface is free from welding temperature deformation.
    2.High temperature resistance
    Because of the more complex horn shape structure, more suitable for pressure or temperature fluctuations of the pipeline or high temperature, high pressure and low temperature pipeline.
    3.High pressure resistance
    The weld interface (groove) type of the welding flange is butt weld, butt weld is easy to weld and test, so in many conditions greater than 25 pressure generally choose butt weld flange for connection. It often used in dangerous medium occasions, transport expensive, flammable, and explosive medium pipeline.
    4.Impact resistance
    Welding neck flange has good impact resistance, which is much higher than the impact of other solid wall pipe materials.
