HEAT EXCHANGER STYLE 940

The term heat exchanger in most processe industries is referred to as the «shell and tube heat exchanger». As the name implies, it is equiped with a «shell» and a bundle of «tubes». One of the fluids flows inside the shell and outside the tubes and the other fluids inside the tubes.

The style 940 is a metallic gasket that has a smooth sealing surface and can be manufactured practically in any shape. Their typical applications are in valves, heat exchangers, hydraulic presses and tongue and groove flanges. The strong points are mechanical and chemical attack resistance and they can be used in elevated temperature and pressure service. The width of the gasket sealing surface should be at least equal to 1.5 times its thickness.
