316 SS Corrugated Metal Full Face Gasket

Full Face gaskets are a flat sealing element, consisting of an inner and outer diameter, and a specified number of bolt holes, the center of which are evenly spaced around a bolt circle. Full face gaskets are designed to fill the entire space between flat-faced flanges, with bolt holes that match the size and arrangement of the bolt holes in the intended flanges. ASME B16.20 govern the dimensions of full face gaskets for standard diameter pipe flanges. A corrugated metal gasket has a metal core with flexible graphite facings. It combines the sealing properties of the flexible graphite with the extrusion resistance of the corrugated metal core. The main advantage for using this type gasket is that it provides an extremely effective seal under low bolt loads. This makes the gasket ideal for applications where the available loading is determined to be low and unsuitable for spiral wound or other type of gasket requiring high seating stress. It is designed to maintain a positive seal through thermal cycling and shock load conditions. These gaskets have passed an industry fire test, a relative indicator of the gasket's ability to resist fire conditions. One of the most frequent uses of a corrugated metal gasket are in shell and tube heat exchangers, due to their ability of to avoid mechanical shearing problems associated other gasket types in heavy thermal cycling applications.
