SILICON CARBIDE SEALS
Silicon carbide seal ring processing by pressureless sintering has excellent thermal conductivity, outstanding thermal shock stability, better wear resistance, heat resistance, chemical resistance and so on. Heated by 1600 degrees Celsius heat, it can suit for high-end mechanical seal. Pressureless-sintered silicon carbide bushing than a reaction-sintered silicon carbide bushing wear resistance, high temperature resistance, corrosion resistance, working environment up to 1650 degrees. It can not only can be applied to petroleum, chemical industry, automotive, military, paper industry, but also be applied to food, pharmaceuticals, nuclear industry and other industries.
