ABSTRACT:
The invention is directed to a metal bellows seal for use in high pressure, extreme temperature installations. The description shows not only a gasket made from a formed tube open on one side to leave a gap that exposes the gasket interior to high pressure process fluid, but also a fin protruding from the opposite side of the tube of a width that is equal to and in general alignment with the gap in the gasket. The gasket is seated within aligned grooves that are formed in opposing pipe flange faces. The fin, clamped between the opposing flanges stabilizes the gasket within the grooves and forms an aperture between the pipe ends that establishes fluid communication between the pipe and the interior of the tubular gasket.
