Supply of spiral wound gasket, metal gasket, metal coated pad

详情

By the pre-forming corrugated metal and nonmetal band with alternating 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 electric power, petrochemical, aviation, chemical

     Labor, fertilizer, polycrystalline silicon, alumina, valves, flanges and other industries.

     Applicable medium: acid, alkali, oil, salt, water, steam, hydrogen, natural gas, pyrolysis gas.

     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.
