  • Patent number: 10955055
    Abstract: A spiral wound gasket includes a resilient sealing element including spirally wound, alternating layers of metal banding and winding fill material that incorporates a significant quantity of talc with quantities of fiber and binder. Either or both of an outer guide ring and inner guide ring may extend from peripheral outer and inner surfaces of the sealing element. Embodiments of the gasket overlay one or both axial faces of the sealing element with a layer facing material that incorporates a significant quantity of talc with quantities of fiber and binder.

  • Patent number: 10894382
    Abstract: A reinforced gasket material. A non-metallic scrim layer is interposed between layers of gasket material to provide strength to the gasket material. The layers of the gasket material can include binding agent to aid adhering to each other and to the non-metallic scrim layer. The non-metallic scrim layer can also be coated in binding agent. The layers of the gasket material can include high-temperature sealing material, compressed fiber, exfoliated graphite, or polytetrafluoroethylene.

  • Patent number: 10400926
    Abstract: Wearable rubber parts for fluid handling systems include a four layer structure, wherein the inner most layer of the four layer structure is a polyurethane layer. The polyurethane can be millable polyurethane. The polyurethane used in the inner most layer can be produced by reacting diisolcyanate with a polyester and/or polyether polyols and a chain extender. The wearable rubber part can be an expansion joint, a pinch valve, or a hose.

  • Patent number: 9732855
    Abstract: An extreme temperature gasket material capable of withstanding temperatures in excess of 850° F. is provided. The extreme temperature gasket generally includes an inorganic filler, an inorganic fiber, and an organic binder. In some embodiments, the inorganic filler is from 75 to 90 wt % of the gasket material and can include submicron-sized talc particles. The inorganic fiber can be from 5 to 20 wt % of the gasket material and can include silicic acid fiber. The binder can be a latex emulsion and can be present in the gasket material in the range of from 1 to 5 wt % of the gasket material. The gasket material also can include additives, such as flocculant and defoamer. In some embodiments, the amount of organic material present in the gasket material is limited to less than 5 wt % of the gasket material.
