Metal gasket seal

Metal gasket seal---Spiral wound gasket:consists of "v-shape"(or"w-shape")metal tape and nonmetal tape,which are overlapped each other and wound continuously. To fasten the metal tape,both its start point end point are tack welded.Feature:1.Wide range of applicable working condition,high temperature and high pressure resistance. applicable to super low temperature and vacuum condition. chemical resistant gasket is available under various medium,through change of composition of gasket.2.Strong strees compensation.stable and reliable sealing performance even under frequent pressure fluctuation condition.3.Perfect sealing performance.4.Normal requirment of flange surface finishing which contact with gasket.5.Easy installation and low pre-tightening stress of gasket.Type:1.four types:basic type,with inner ring,with outerring,and with inner&outer rings. . Technical data:1.Working temperarure: -200---8702.Working pressure: 30MPa3.Gasket coefficient:m=2.5 4
