Structural classification of stainless steel flanges
1. Smooth type: used for stainless steel valves with low pressure. It is more convenient to process;
2. Concave-convex type: high working pressure, medium-hard washers can be used;
3. Tongue and groove type: gaskets with larger plastic deformation can be used, which are widely used in corrosive media and have better sealing effect;
4. Trapezoidal groove type: use an oval metal ring as a gasket, used for valves with a working pressure of ≥64 kg/cm², or high temperature valves;
5. Lens type: The gasket is in the shape of a lens and is made of metal. Used for high-pressure valves with working pressure ≥ 100 kg/cm², or high-temperature valves;
6. O-ring type: This is a relatively new form of flange connection, which is developed with the emergence of various rubber O-rings.
