Heat Exchanger Gasket is a term that has been given to gasket used in heat exchangers. The structure of the gasket or its type varies according to the operating conditions of the exchangers. The heat exchanger gasket come in a wide spectra of tyres including single or double jacketed, corrugated, plain metal, soft and many other. A large selection of different materials allows heat exchangers to operate at temperatures beyond the capabilities of most soft gasket materials. These gaskets are used in shell and tube type heat exchangers. They can be manufactured in very different sizes, shapes, with or without bars. The primary seal is at the inner diameter of the gasket, the outer gasket diameter acts as a secondary seal. The bars seal between the heat exchangers passages. The Heat Exchanger gaskets are produced in several types to meet the most demanding application. Gasket for heat exchangers can be manufactured in metal or alloy with a thickness 0.4mm featuring a soft core inside metallic jacket.
