Properties and application
Heat Exchanger Gasket is a term that has been given to gasket used in heat exchangers. The structure of the gasket or its type vary according to operating conditions of the exchangers. The DONIT TESNIT® heat exchanger gaskets come in a broad spectre of types 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.
Available in a wide range of materials, since they are all custom made. There are few limitations regarding size and shape.
Metal jacketed heat exchangers - The metal jacket provides mechanic strength to contain the filler and improves chemical resistance.
Unique construction provides stability and ensures trouble-free handling and installation.
Shape and construction
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 external gasket diameter acts as a secondary seal. The bars seal between the heat exchangers passages.
The DONIT TESNIT® heat exchanger gaskets are produced in several types to meet the most demanding applications. Gaskets for heat exchangers can be manufactured in metal or alloy with a thickness of 0.4 mm featuring a soft core inside a metallic jacket.
