The graphite gasket sealing material is made from natural flaky graphite that has undergone special chemical treatment and thermal processing, maintaining the original characteristics of natural graphite and providing excellent sealing performance.

II. Features:
1. High temperature and low temperature resistance, with a usage range of degrees Celsius in non-oxidizing media, and up to 400°C in oxidizing media.
2. Corrosion resistance against various corrosive media, though there are certain limitations when used in strong oxidizing media.
3. The maximum pressure limit for the gasket is 1.33X10<59Mpa, ensuring good sealing even under severe temperature and pressure fluctuations.
4. Asbestos gaskets tend to leak due to capillary action with liquid media, whereas graphite gaskets have excellent impermeability.
5. The flange sealing surface does not require precision machining; a surface roughness of RA6.3mm is sufficient to ensure sealing.
6. The gasket is soft and has good elastoplasticity, thus requiring less bolt tightening force; a gentle compression of the gasket guarantees good sealing and facilitates installation.
7. Non-stick sealing surface.

III. Materials: Flexible graphite, stainless steel, tinplate.

IV. Application Range: Applicable pressure: 20 Mpa; Applicable temperature: -200℃ to 870℃; Applicable media: steam, compressed air, natural gas, cracking gas, conversion gas, petroleum products, solvents, residual oil, wax oil, oil slurry, heavy oil, propylene, caustic soda, molten salt heat carriers, acids, bases, salts, solutions, liquefied gas, water, etc.

V. Main Uses: Used for static sealing at flange connections in pipelines, pumps, valves, pressure vessels, heat exchange equipment, and other media.

VI. Specifications: DN10-DN900, can also be produced according to the specifications and dimensions provided by the buyer.
