Single Jacketed Overlap gasket
Description
Metal Double Jacket Gasket is a composite gasket with internal nonmetal material such as flexible graphite, Teflon, asbestos- rubber sheet and ceramic fiber which is clad by special meta sheet in cold work. Proper medium, pressure and temperature are decided by different materials we use. The highest temperature is 1300°C and the highest pressure is up to 100Mpa.
Application
Applicable to middle and low pressure condition.
Normally used as flange sealing in large diameter pressure vessels such as heat exchanger and reactor.
