    Ceramic material, as an inorganic non-metallic material, has many properties that metal materials do not have, such as: high strength, high hardness, high elastic modulus, high temperature resistance, wear resistance, corrosion resistance, oxidation resistance, heat shock resistance.

    Ceramic Ring is a solid Ceramic gasket that has been processed into octagonal or oval shaped solid Ceramic with a radial self-sealing effect.Ceramic Ring are in contact with the inner and outer sides (mainly the outer sides) of the flange trapezoidal groove as well as formed as seals by compression.


    Ceramic Ring are divided into octagonal ring gaskets and elliptical gaskets.The metal ring gasket is divided into octagonal and elliptic structures according to the section shape.
     
    Ceramic Ring and flange groove match, the main performance of surface contact.With elliptic annulus gasket photograph is compared, although not easy and flange groove achieves close close, but can use again, and because section is formed by straight line, easy machining.Elliptic ring gasket in flange groove is the line contact, sealing is good, but the processing accuracy requirements are high, thus increasing the manufacturing cost, at the same time the elliptic ring gasket can not be reused.

    Product advantage
    1. Chemical corrosion resistance
    2. Fall resistance
    3. Wear resistance
    4. High temperature resistance
    5. Anti-static
    6. Fire resistance
