Heat exchanger gasket is a term used for gaskets used in shell and tube type heat exchangers. This is usually a metal jacketed gasket with a soft filler for higher temperatures. The styles, materials, configurations are limitless.
Metal jacketed gasket is made from graphite , ceramic, non-asbestos etc. filler covered with thin metal jacket, such as stainless steel , soft iron,carbon steel, copper etc. By their sealing efficiently, provide outstanding resilience, while the metal jacket guarantees excellent sealing and protects the filler against pressure conditions , fluctuating temperatures and corrosion.Metal Jacketed Gasket is particularly suitable for sealing flat surfaces of heat exchanges, gas pipes , cast iron flanges , cylinder heads of engines as well as for boilers and other vessels.By their sealing efficiently, provided by exerting strong pressure on circular rimes of the flanges, metal-jacketed gaskets can stand up to 30% deviation from the initial thickness, which is very useful in case of irregular or faulty flange rims. The chemical compatibility of the metal and the medium being sealed should be considered.
