ABSTRACT:
An electrical isolation, high pressure resistant gasket for API or ANSI seal ring flanges has four combined features. The gasket has two relatively thick, unyielding metal plates electrically separated from each other by an insulating material. The outer face surfaces of the metal plates are grooved for metal seal rings. The inner face surfaces have metal ridges. The insulating material electrically isolates the plates and the strength of the plates and metal ridges prevent distortion of the plates and blowout of the insulation material. Preferably, the metal ridges extend inwardly overlapping each other. The metal plates may be made of dissimilar metals.
