Flange

Function: The core function is to cooperate with the gasket through the surrounding bolt holes to realize the detachable connection of pipes, valves, equipment and other components, with structural stability and sealing. Structure type: according to the structure can be divided into flat welding, butt welding, thread and other types. Flat welding flange has poor rigidity and is suitable for occasions with pressure p ≤ 4MPa. Butt welding flange, also known as high neck flange, has high rigidity and is suitable for occasions with high pressure and temperature. Sealing surface form: including plane, concave and convex surface, tongue and groove surface, etc. Flat sealing surface is suitable for occasions where the pressure is not high and the medium is non-toxic; concave-convex sealing surface is suitable for occasions with slightly higher pressure; tongue and groove sealing surface is suitable for flammable, explosive, toxic medium and high pressure occasions.
