The structural shapes of stainless steel flanges are classified as follows:
1. Smooth type: for stainless steel valves with low pressure, it is more convenient to process.
2. Concave-convex type: The working pressure is high, and 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 washer, 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. It is used for high-pressure valves or high-temperature valves with a working pressure of ≥100 kg/cm².
6. O-ring type: This is a relatively new form of flange connection, which is developed with the emergence of various rubber O-rings.
