Double Jacketed Gasket SWG815 Metal Jacketed gasket(MJG)is made from graphite,ceramic,non-asbestos etc.filler covered with thin metal jacket,such as stainless teel,carbon steel,copper etc., special used in sealing spots of heat exchanger,pressure vessel etc. this gaskets highly resistance against blow-out ,suitable for high assembly stress .     Filler material Jacket meterial Temperature（°C） Pressure（Mpa） Graphite, Asbestos Non-asbestos Ceramic、PTFE Carbon steel 350 ≤6.4 Copper 450 ≤6.4 3.4、316 530-600 ≤6.4   DN DN 15~5000mm material L2,T2,08F,304,321,316,316L , Handtailor Asbestos sheet , Flexible Graphite, PTFE, earthen fibre mostly performance Double Jacketed Gasket has characteristic of metallic and nonmetal, with excellent sealing performance, especially made of each kind of complex shape. Double Jacketed Gasket with greatness diameter not easy to fall apart and not easy to damnify, the most temperature is 800, the pressure is ≤6.4Mpa，the leakiness rate is 1�w10-3cm3/S. If both of sides be adhered flexible graphite, the leakiness rate is 1�w10-5cm3/S。 purpose Double Jacketed Gasket can be used in sealing spots of pressure vessels, exchanger heat, condenser, plain hole, etc. The Ripple Double Jacketed Gasket be used in various pipe and flange. standard GB/T1560-1995,JB4706-92,JB/T4718-92,HG20630-97,ANSIB16.3,API,JPI, etc.
