Abstract: A method of making a gasket having a high temperature coating that includes obtaining a substrate formed from a metallic material and having the shape of a gasket, applying a nanoparticle suspension over the outer surfaces of the substrate, and heating the substrate to a first elevated temperature to form an undercoat layer of a self-protective oxide coating. The method also includes applying a liquid comprising boron nitride over the undercoat layer and drying the boron nitride liquid at a second elevated temperature to form an overcoat layer.

Abstract: Gasket stock is disclosed having a rectangular metal core that is readily bendable in one direction and a deformable rubberized jacket coextruded with and encasing the metal core. A method of fabricating the gasket stock through a coextrusion process is disclosed. A method also is disclosed for forming a press-in-place gasket with the method including obtaining bendable gasket stock, incrementally advancing the gasket stock to predetermined positions in a bender, and bending the gasket stock at the predetermined positions along its length to form a desired shape of the press-in-place gasket. The bender is controlled by a computer to form the shape of the gasket according to a CAD or other electronic file. Finally, a method of supplying press-in-place gaskets and accommodating design changes of such gaskets is disclosed.

Abstract: A gasket for creating a seal between two surfaces. The gasket may include a pervious base sheet and a permeating material applied to or incorporated into the base sheet. The gasket is formed by various methods disclosed herein. The gasket may include a base sheet, a primary sealing material covering the base sheet, and a secondary sealing material covering the primary sealing material.

Abstract: An edge coated gasket includes a base sheet made of compressible gasket material and having opposed faces and an interior edge surrounding and defining an aperture. An edge coating of polymer or other material is disposed on and seals the interior edge of the base sheet and may project beyond the facial planes of the base sheet to define protruding rims extending around the aperture. Face coatings may also be applied to one or more of the faces extending in relatively narrow strips around the aperture of the base sheet. When clamped between flange surfaces, the edge coating engages, conforms to, and seals against the flange surfaces to provide a seal against both interfacial and intersticial migration of fluid past the gasket. At the same time, the inherently good compression failure resistance of the compressible gasket material of the base sheet is preserved. Thus, a gasket with enhanced sealability and compression failure resistance is provided.

Abstract: A gasket with selectively positioned seal enhancement zones located in the web of the gasket is provided. The gasket is formed of a base sheet of gasket material cut to define an interior aperture bounded by an interior edge and webs. Slots are formed at selected locations within the seal enhancement zones and the slots are bounded by edges. An edge coating of polymeric material is applied to the slot edges and, in one embodiment, project beyond the facial planes of the base sheet to form raised rims. An edge coating also may be formed on the interior edge bounding the aperture of the gasket. When clamped between a pair of flange surfaces, the polymeric edge coatings on the slot edges engage and seal against the flange surfaces within the seal enhancement zones to provide an enhanced seal against leakage in these zones.

Abstract: An improved gasket (11) for sealing the joint between a pair of flange surfaces is provided. In one embodiment, the gasket (11) is an edge coated gasket and the edge coating (14) also exhibits surface adhesion to enhance the seal provided by the gasket. In another embodiment, compressible sealing members (34, 44) are coated with a coating material (37, 47) that exhibits surface adhesion properties.

Abstract: A gasket having two opposed faces and an edge disposed therebetween is given a wide coating on the edge. The coating is sufficiently wide so that it goes from corner to corner on the edge and protrudes past the corner on at least one side of the gasket in a direction perpendicular to a facial plane of the gasket. The coating protrudes in an amount effective to give the gasket a sealing ability which is better than the sealing ability of the same gasket if it had a coating merely extending from corner to corner without protruding. A process for coating the gasket edges which are around the aperture comprises placing the gasket sheets together so that a cavity is formed by the apertures, the sides of the cavity are the aperture edges to be coated. The coating material is put into the cavity and contacts the edges to be coated to form the coated edges.

Abstract: A gasket which is compression-failure resistant, even at operating flange pressures in the range of from about 3,000 to about 15,000 PSI and also has a good sealing ability, comprises a soft gasket material having two opposed, facial surfaces and an aperture with an edge perpendicular to the facial surfaces, wherein the edge of the aperture has a polymer coating (coating A) on the edge for a good sealing ability. In this embodiment, except for coating A, the gasket is otherwise not coated which makes the gasket compression-failure resistant. In embodiments which need even better sealing ability, at least one of the opposed, facial surfaces has polymer coating B, which may abut both the edge and polymer coating A, wherein polymer coating B on the facial, opposed surface leaves the gasket uncoated for sealing ability in an amount effective to give the gasket compression failure resistance.

Abstract: A soft gasket material having two opposed facial surfaces and an edge that is substantially perpendicular to those surfaces has a coating on the edge. The coating has a thickness length B which is a distance extending directly from the edge at its center point to the coat's outer surface. The coating further covers the edge from side to side and extends past at least one corner of the edge in a protruding length A which is an amount that is effective to form a barrier against the passage of fluids onto the face of the gasket. In coatings where the protruding length A is not supported by the gasket face, the ratio of protruding length A: thickness length B must be at least about 0.8, protruding length A must be a minimum of at least about 4 mils, and thickness length B must be a minimum of at least about 3 mils. In coatings where the protruding length A is supported by the gasket face (a distance C), the ratio of protruding length A: thickness length B can be at least about 0.
