Information

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.

  • Difference analysis between butt welding flange and special-shaped flange
    Difference analysis between butt welding flange and special-shaped flange The sealing surface of butt welding flange can be made into three types: smooth type, concave-convex type and tongue-and-groove type. The application of smooth butt welding flange is large. Generally, it is mostly used when the medium conditions are relatively moderate, such as low-pressure unpurified compressed air and low-pressure circulating water. Its advantage is that the price is relatively cheap. Butt welding flanges are suitable for pipelines with large fluctuations in pressure or temperature or pipelines with high temperature, high pressure and low temperature, and are also used for pipelines that transport expensive, flammable and explosive media. The welding method used when connecting the flange and the pipeline of the butt welding flange is butt welding. The welding seam is similar to the welding of pipelines and pipelines. Generally, argon arc welding is used for the bottom of the small pipe diameter, and the cover surface is manually welded. Only use double-sided welding.
