    摘要: An isolation gasket for use between facing flanges of two flow conduit sections for fluid passage therethrough. The isolation gasket includes non-conductive layers and coatings that cover a flat metal core ring to provide electrical isolation, and a fire resistant layer adjacent another non-conductive layer wherein this side by side arrangement uniquely maintains a seal during a fire. In one form, a serrated ring portion of the flat metal core ring has a convex profile.
