METALBEST STYLE 927

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 927 gaskets are manufactured covering both sides of the 923 style gasket with flexible graphite corrugated tape. The flexible graphite cover increases the gasket sealability, especially if the flange sealing surfaces have pitting, tool marks or other small irregularities. This gasket combines the welded bar construction advantages with the excellent sealability of the flexible graphite, which fill up the small irregularities, providing a high sealability seal.
