Heat Exchanger Gaskets
A "Heat Exchanger Gasket" is a term that has been giving to the gasket that is called out for use in an exchanger. The make up of the gasket or type varies due to the operating conditions of the exchanger. Metallic gaskets can come in different types like Double Jacket, Single Jacket, Solid Metal or a Spiral Wound. Soft compressible material can be Rubber, CAF, PTFE, or Non-Asbestos Compressed sheet type.
Single Jacketed Gaskets
The filler material is enclosed in a metal jacket which covers the inside and outside diameter of the gasket.
Double Jacketed Gaskets
The filler material is completely enclosed by a two piece metal jacket, which covers both the inside and outside diameters and both contact surfaces.
Soild Corrugated Metal Gaskets
As the name suggests, the solid corrugated metal gasket is comprised solely of metal and does not contain any non-metallic fillers in its construction. The temperature limitation of the gasket is therefore only effected by the metal selected.
