With inner and outer ring spiral wound gasket seals

الوصف

By the pre-forming of the metal V-belt with metal straps alternately overlapping spiral wound is made

     And under the conditions required to add reinforcement ring. Because having a multi-channel sealing, high temperature resistance, corrosion,

     Flange sealing surface roughness of less demanding, it is widely used in power stations, aviation, petrochemicals,

     Valves and other industries.
     Applicable medium: steam, hydrogen, natural gas, pyrolysis gas, oil, acid, alkali, salt solution, etc.
     Benefits:
    1, a good compression ratio and elasticity
    2, a suitable plastic, after pressing the sealing surface can adapt to fill the sealing surface irregularities and gaps,

        To ensure that the system temperature and pressure in the case of alternating with good sealing performance
    3, tensile strength, elongation, good mechanical properties
    4, has an excellent corrosion resistance, in extreme medium is not damaged, do not produce a large expansion and contraction
    5, the high temperature does not soften, no creep; temperature conditions without hardening, no shrinkage
    6, there is sufficient strength, external load conditions, it is not crushed; under high pressure, is not blown.
