  • Patent number: 10001235
    Abstract: Gasket seals for high pressure applications include retaining elements with inner diameter seal elements that interlock with the retaining element to provide resistance to movement in both axial and radial directions between the retaining element and seal element. High pressure sealing may be accomplished using a metallic core retaining element to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through an inner diameter dielectric sealing element, such as a polytetrafluoroethylene (PTFE) inner diameter sealing ring. Flanges of a joint in a fluid flow ling may be bolted together with the gasket seal interposed therebetween. In the event of pressure changes, the inner diameter seal resists being drawn into the flow line, and resists axial movement relative to the retaining element, through dual locking members that secure the seal to the retaining element.

  • Patent number: 8622398
    Abstract: A seal assembly capable of low temperature service is disclosed. It features upper and lower metallic backup rings that are specially shaped to act as a spring to keep the sidewalls of such rings in contact with the inside and outside surfaces to be sealed to prevent extrusion of the seal material even in low temperature situations. Inner and outer grooves are provided. O-ring seals, used for the ID of the seal, are manufactured to have a slightly greater diameter than the groove into which they will be installed. The greater length provides stored energy to promote sealing functionality in cold temperature situations. The O-rings used for the OD of the seal are manufactured to have a slightly smaller diameter than the groove into which they will be installed. The shorter length provides stored energy to promote sealing functionality in cold temperature situations.

  • Patent number: 8567792
    Abstract: A resin sub-seal member (11) provided with a concave groove (16) is disposed at a region closer to a higher-pressure side region than a rubber main seal member (10) and pressure variation in a gas on a higher-pressure side is inhibited from being transmitted to the main seal member (10). Further, a variation reducing space (13) is formed between the seal members (10) and (11) to be able to reduce the pressure variation when gas leakage in the sub-seal member (11) occurs or the sub-seal member (11) responds with a delay with respect to the pressure variation. Thus, rapid change in the pressure of the gas surrounding the main seal member (10) is inhibited, occurrence of the blistering phenomenon is inhibited, and a high seal ability is achieved. The seal structure is formed by a simple structure including the seal members (10) and (11), and the variation reducing space (13).
