Product description

The core application of corrosion resistance graphite ring lies in achieving long-term, stable seals under harsh conditions. They are primarily installed on the dynamic and static sealing surfaces of valves, pump bodies, reactors, and pipe flanges. Their core function is to effectively isolate media, preventing leakage of high-temperature steam, corrosive acids and alkalis, organic solvents, or flammable and explosive gases. This not only ensures the continuity of production processes and process safety but also avoids environmental pollution and resource waste caused by media leakage, acting as a "gatekeeper" for the safe operation of industrial equipment.

Compared to ordinary sealing materials, the advantages of corrosion resistance graphite ring mainly stem from their advanced isostatic pressing process and the natural properties of graphite.
1. Excellent corrosion resistance: They exhibit excellent resistance to most acids, alkalis, salts, and organic compounds, except for strong oxidizing acids.
2. Excellent temperature and pressure resistance: The product can operate stably in a wide temperature range from -200°C to 850°C, and some high-end products can even withstand extreme temperatures up to 2500°C. At the same time, they can withstand working pressures up to 30 MPa or even higher.
3. Excellent self-lubrication and high thermal conductivity: Graphite material has a very low coefficient of friction, which reduces wear on the sealing surface and extends service life. Its high thermal conductivity helps to quickly dissipate heat, preventing sealing components from failing due to overheating.
4. High strength, density, and stability: Graphite materials prepared by isostatic pressing technology have high density, a highly uniform and isotropic structure, and possess high mechanical strength and dimensional stability, maintaining reliable sealing even under thermal cycling and pressure fluctuations.
