International Classification:

F16L 23/22
F16J 15/10

Abstract:

A non-metallic flange isolation gasket kit sealing flanged pipeline connections and flanged vessel connections while providing electrical isolation protection between flanges suited for high-pressure and high-temperature cathodic protection applications is presented. The invention protects flange faces from media induced corrosion and mitigates flange rotation induced fatigue and failures. The invention comprises of a retainer, a seal, and a seal pre-load structural ring. The seal pre-load structural ring is inserted into the seal, and seal outer diameter surface is joined to the retainer inner diameter surface. A second embodiment comprises of a composite gasket blank, comprising of a retainer and a seal, and a seal pre-load structural ring. The seal outer diameter surface and the retainer inner diameter surface are joined by thermal fusion bonding. The invention may further comprise one or more gasket seating stress stabilizers and/or a centering ring. Tapered retainer upper and lower surfaces decrease flange rotation.
