Graphite sealing ring is a commonly used sealing material in mechanical seals, which has the advantages of high strength, high wear resistance and high corrosion resistance. In mechanical seals, the use of graphite sealing rings can effectively prevent fluid leakage and ensure the normal operation of mechanical equipment.
The carbon-graphite materials used in graphite sealing rings can be roughly divided into the following categories:
1.Ordinary graphite material.
Ordinary graphite material is the most commonly used graphite sealing ring material, which has good corrosion resistance and high wear resistance. In mechanical seals, ordinary graphite materials can effectively prevent fluid leakage and can adapt to various working conditions.
2.High purity graphite material.
High-purity graphite materials refer to carbon-graphite materials with high graphite content, and their purity can reach more than 99%. High-purity graphite material has better corrosion resistance and high strength, and is suitable for high temperature, high pressure, and highly corrosive working environment.
3.Impregnated graphite material.
Impregnated graphite material refers to the graphite material that has been impregnated with a surface that has better wear resistance and corrosion resistance after special treatment. The impregnated graphite material is suitable for high-speed rotating mechanical seals, which can effectively improve the sealing effect.
4.Metallic graphite material.
Metallic graphite materials refer to carbon-graphite materials that combine metal with graphite. This material has better electrical and thermal conductivity and is suitable for working environments that need to withstand high temperatures, high pressures, high corrosiveness, and where electrical or thermal conductivity is required.
In short, the carbon-graphite materials used in graphite sealing rings can be roughly divided into the above categories, and different types of carbon-graphite materials have different performance characteristics and are suitable for different working environments. When choosing a graphite sealing ring, it is necessary to select the appropriate carbon graphite material according to the specific working environment and use requirements.
