摘要： The present invention concerns a gasket assembly (1) for sealing between conduits passing through two respective bodies. The gasket assembly comprises a primary seal (10), wherein the primary seal comprises a first sealing surface (14) adapted to form a seal with the first body of said respective bodies, and a second sealing surface (15) adapted to form a seal with the second body of said respective bodies. The primary seal is coupled to a primary seal carrier (30), the primary seal carrier comprising one or more secondary seals (43a, 43b), the one or more secondary seals being adapted to form a seal with one or more of the first and second bodies.

摘要： A seal arrangement includes a seal assembly and a seal subassembly in operable contact with the seal assembly. The seal subassembly is configured to impart energy to the seal assembly to promote sealing of the seal assembly with a mating surface. A non-sealing feature of the seal subassembly depends from the seal subassembly and is interactive with a load shoulder of a structure adjacent the seal subassembly. The seal arrangement redirects a mechanical load path through the seal subassembly to the non-sealing feature, during use. A method of protecting a seal subassembly from reverse loading is by redirecting a load path through a seal subassembly to a non-sealing feature, while also permitting pressure energizing of the seal assembly by the seal subassembly in a sealing direction. A downhole system includes a borehole in a formation, a string in the borehole, and a seal.

摘要： A pressure retained gasket seal provides enhanced resistance to hydraulic unloading by including a notch formed in a rear face of the gasket groove, thereby reducing intrusion of process fluid behind the gasket and improving hydraulic retention of the gasket seal. Embodiments increase the process fluid pressure limit of the gasket seal by a factor of two or three compared to gasket seals of the prior art. In embodiments, the gasket groove has a dovetail cross-section, thereby increasing resistance to process fluid pressure by requiring compression of the gasket before it can be dislodged from the groove. Embodiments form the gasket from flexible graphite, which can be initially shaped as an annulus and then forced by an applied load into the gasket groove in conformance with the notch. Embodiments include compressing the graphite to within 50% or even 70% of its maximum density during installation thereof.

摘要： The disclosure relates to a sealing device comprising a sealing device comprising an annular substrate comprising an inner periphery defining a shaft hole; and a plurality of carbon nanotubes extending outwardly from and around the inner periphery into the shaft hole. In various practices, a plurality of annular metal mesh substrates is axially interposed and sandwiched between the first annular frame and a second annular frame, with a portion of the substrates comprising the carbon nanotubes extending outwardly from and around the inner periphery into the shaft hole. In another practice, the a solid annular metal substrate is used and a plurality of carbon nanotubes that extend into the shaft hole each have a first end attached to the inner periphery whereby the second end extends into the shaft hole. The device is useful in e.g. gas compressors.

摘要： The invention relates to a sealing device of a system for sealing a fluid passage from a first component (1) to a second component (2), comprising at least one first sealing element (3) which is of an annular design to allow fluid to pass through it, includes at least one expansion slot (4) and has a first sealing surface (5) sealingly associated with the first component (1) and has a second sealing surface (8) sealingly associated with the second component (2), said at least one first sealing element (3) being flexible and said expansion slot (4) being designed in such a way that radial and resultant axial pressure of the fluid passing through there will cause the first sealing element (3) to expand in the radial direction and thus press radially in the direction against the first component (1), with said first sealing surface (5) with the expansion slot (4) being sealed against the first component (1) by abutment in the direction of the latter, and in such a way that the first sealing element (3) will press axially in the direction against the second component (2), with the second sealing surface (8) with the expansion slot (4) being sealed against the second component (2) by abutment in the direction of the latter.

摘要： An electrically isolating gasket is disclosed wherein a coating layer is disposed on at least one conductive surface, and in some embodiments, on all surfaces or at least all of the conductive surfaces. The electrically isolating gasket includes a core gasket component, a ring seal component, and a non-conductive inner seal component. The coating layer can be, for example, polyimide, polyamide, ceramic, and aluminum oxide.

摘要： A termination fitting assembly for use with a conduit includes the conduit comprising a primary pipe positioned centrally within a secondary pipe along a longitudinal axis of the conduit and the conduit having an interstitial space defined between the primary pipe and secondary pipe. The termination fitting assembly includes an interior fitting having an inner wall and an outer wall, the inner wall sized and shaped for insertion into and sealing with the primary pipe, and the outer wall extending circumferentially around the secondary pipe of the conduit. The termination fitting assembly includes an annular channel defined between the inner wall and the outer wall of the interior fitting and in fluid communication with the interstitial space of the conduit and an exterior fitting positioned around the conduit.

摘要： High temperature dryer seals and related methods are provided. A high temperature dryer seal can include a first substrate having first and second ends and first and second sides. The first substrate can include a low-melt polymer. The first end and the second end of the first substrate can secured together so that the first substrate forms at least a portion of an annular shape. The dryer seal can also include a second substrate secured to the first substrate at the second side of the first substrate. The second substrate can include a high temperature material that has a higher melting point than the low-melt polymer of the first substrate. The dryer seal also includes a heat resistant coating attached to the second substrate with the heat resistant coating being activated at a temperature that is higher than a melting point of the low-melt polymer.

摘要： Apparatuses for controlling fluid flow are important components for delivering process fluids for semiconductor fabrication. These apparatuses for controlling fluid flow require a variety of fluid flow components which are tightly packaged within the apparatuses for controlling flow. Servicing the apparatuses requires specialized equipment and methods which enable installation of seals in close quarters in apparatuses which are installed in the field. Seal insertion tools may be used to facilitate installation of the seals to permit efficient assembly of fluid flow components into apparatus for controlling flow.
