Butt flange: Weld Neck Flange is usually called “high hub” flange. Its purpose is to transfer the pressure of the pipe, thereby reducing the high stress concentration in the flange base. However, the price is high, because the production process is complex.
Flange has served the widely used in Petroleum Industry, Chemical Industry, Gas Industry, Machinery Industry, Electric Power Plant, Shipbuilding Industry, Papermaking Industry, Metallurgy Industry, Carbonization Industry, Refrigeration Industry, Light Industry, Salt Industry, Construction Industry and waterworks industries.
