Metal wound gasket with asbestos is a type of widely used sealing gasket at present, and its resilience is regarded as the best in semi metallic gasket. Wounded together alternately by V or W shaped steel strips and various fillers, the product has good heat resistance, high pressure resistance and adapt to the use of ultra low temperature or under vacuum conditions. Through changing the material combination of the gasket, the problem of all kinds of medium chemical corrosion on the gasket can be solved. The structure density can be made according to different locking force requirements . In order to strengthen the body and accurate positioning, the inner reinforcing ring, outer locating ring ,inner and outer steel ring are set within the asbestos metal winding gasket to control its biggest compaction degree. It doesn’t have much requirements on the precision of the flange sealing surface contacted with the gasket.
适用范围 Application scope
Asbestos metal winding gasket with excellent resilience can be automatically adjusted towards the pressure thermal cycling and vibration of the piping system . It is especially suitable for the situations with inhomogeneous load, slack composition of forces , periodical changes of temperature and pressure ,impact or vibration. It is the original static sealing in flange connection of valves, pumps, heat exchangers, towers, handholes, etc and is widely applied in sectors of petrochemical, machinery, electric power, metallurgy, ship ,building, medicine, atomic energy and aerospace.
