  • Patent number: 9784404
    Abstract: A method of making a lightweight thermal shield that includes obtaining a mold having a shaped support screen with a molding surface configured to allow the passage of air and moisture therethrough, and with the mold being adapted for drawing a vacuum from behind the support screen. The method also includes applying a wet insulation material onto the molding surface of the support screen and drawing a vacuum to withdraw moisture through the support screen and consolidate a layer of insulation material on top the molding surface. The method further includes removing the consolidated layer of insulation material from off the molding surface, installing the consolidated layer of insulation material into an outer shell layer, and drying the consolidated layer of insulation material within the outer shell layer to form a lightweight core insulation layer.

  • Patent number: 9486833
    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.

  • Publication number: 20150137508
    Abstract: A sleeve for sealing an annular gap between opposed co-axial surfaces of a slip joint includes a tubular body formed from a metallic material and having a first end, a second end, a center section between the first and second ends, and a longitudinal cross-sectional profile having a plurality of bendable curves. The sleeve is shaped so that two or more of the bendable curves contact each opposed coaxial surface to form two or more circumferential lines of contact with each opposed coaxial surface. The sleeve further includes a self-protective oxide undercoat layer that protects the metallic material and a lubricous overcoat layer that provides lubricity to the contact surfaces when the sleeve is exposed to temperatures greater than about 600° C.

  • Publication number: 20110031704
    Abstract: A segmented gasket is formed from two or more gasket segments arranged end-to-end. In one embodiment, the end portions of the gasket segments overlap a predetermined amount to define a region of overlap having a thickness greater than the thickness of the individual gasket segments. An embossed region extends along the gasket segments and aligns in the region of overlap. When compressed between two flanges to be sealed, a continuous seal is formed from one gasket segment, across the region of overlap, and to the other gasket segment. In another embodiment, the gasket segments are locked together with interlocking tabs that project laterally from the end portions of the gasket segments and that are positioned outside of a joint within which the gasket segments are clamped. In a preferred embodiment the gasket segments are metal or rubber coated metal core gasket segments.

  • Patent number: 7278639
    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.
