  • Patent number: 10030774
    Abstract: A metal seal fitting for use on a pipe or pipeline includes at least one metal seal ring having a C-profile which houses a spring and is arranged concentric to, and outside of, a tap diameter of the access connection. The seal ring is double-curved so that it conforms to a pipe-facing side of the fitting. A surface of the pipe is prepared to receive the seal and, as the fitting is being secured to the pipe, the seal is activated and spring-energized. In its final sealing state, the seal is not compressed passed its deformation point and maintains its spring-back capability. After the fitting is removed from the pipe, the seal may be re-used. The metal seal fitting is suited for applications requiring a high integrity seal and can be used in high pressure, high temperature, and highly corrosive environments which are not well-suited for elastomeric seals.

  • Patent number: 8708306
    Abstract: A tunable valve assembly reduces valve-generated vibration. One embodiment comprises a valve body and valve seat having substantially collinear longitudinal axes. A rebound characteristic frequency is associated with rebound of the elastic valve body base plate from forceful contact with the valve seat. A central cavity in the valve body encloses a spring-mass damper optionally immersed in a dilatant liquid and having a damper resonant frequency approximating a pump housing resonance. A lateral support assembly adjustably secured to the valve seat has a support resonant frequency designed in conjunction with the rebound characteristic frequency and the damper resonant frequency. Combined hysteresis heat loss associated with the above three vibration frequencies is reflected in lower closing energy impulse amplitude and damping of associated vibrations.

  • Patent number: 8678398
    Abstract: Sealing systems for high pressure applications that provide electrical isolation between joined elements as well as enhanced resistance to leakage of media during a fire. High pressure sealing is accomplished using a metallic core to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through a dielectric sealing element, such as a spring-loaded polytetrafluoroethylene (PTFE) ring. Flanges of the joint may be bolted together with the seal interposed therebetween, and the flanges bolted together. In the event of a fire, heat may be generated that is at a high enough temperature to burn away the isolating material and PTFE ring. Systems of various embodiments provide a metal core backup seal and a compression limiter, which, respectively, prevent the media from leaking from the joint and maintain bolt load at the flanges.

  • Patent number: 8414032
    Abstract: An automatic discharge connection device of a submersible pump is provided, which includes a coupling member coupled to a discharge port of the submersible pump and a feed pipe that feeds water discharged from the submersible pump. A sealing member is installed in an annular concave portion formed on an inner circumference of the coupling member in such a way as to move left and right. When the submersible pump is actuated, the sealing member moves toward the feed pipe and an end portion of the sealing member enters the feed pipe. Accordingly, a space between the coupling member and the feed pipe is sealed to thereby prevent water leakage between the coupling member and the feed pipe.

  • Patent number: 8403337
    Abstract: A multifunction ring symmetrical about a longitudinal axis has an elastomeric body, first and second ends, and inner and outer surfaces. The elastomeric body totally encloses at least one pair of longitudinally-spaced circumferential tubular cavities, each pair of cavities being mutually connected via a fluid flow restrictor and substantially filled with at least one fluid medium. Each fluid flow restrictor is responsive to longitudinal compression of the elastomeric body, and the fluid medium facilitates heat conduction, vibration damping, extrusion blocking and/or fluid pressure transmission. Longitudinal compression of a multifunction ring on a pump pressure stroke increases tubular cavity fluid pressure and causes substantially symmetrical radial ring expansion. Radial ring expansion is both inward and outward, thus reducing fluid flow resistance in the fluid flow restrictor.

  • Patent number: 8393400
    Abstract: A wellhead or Christmas tree seal assembly that forms a metal-to-metal seal between inner and outer wellhead or Christmas tree members. U-shaped metal seals having legs that face in opposite directions, are bonded to a wiping element. During installation of the seal assembly, the ends of the seal legs seal against the wellhead members and the wiping element compensates for defects on the surfaces of the wellhead members. The wiping element can be of an elastomer, metallic, or intercalated graphite material.

    Abstract: A gasket includes a plurality of corner sections each having a cross-section having a width of at least a first dimension. A plurality of deformable sections are disposed between a pair of the plurality of corner sections, each of the plurality of deformable sections having a cross-section having a width less than the first dimension and having a curved shape that is deformable to a straight shape in its installed condition. The deformable sections allow the gasket to be formed with a smaller molding footprint than the assembled gasket shape and the plurality of corner sections have a same angled orientation in its installed and un-installed positions.

  • Patent number: 8328203
    Abstract: A sealing system, in particular for sealing multiple part exhaust-gas lines for an internal combustion engine, has at least a first flange part (9) and a second flange part (11) guiding a flow of heat (5). The flange parts (9, 11) delimit a receiving space (33) for at least one sealing element (31) between them and adjoin one another. Each flange part forms an outwardly projecting annular flange (13) facing away from the flow of heat (5), and extending transversely with respect to the heat flow. Chambering of the receiving space (33) is formed for the sealing element (31) by an annular groove (45) open at the end face (17) of at least one flange part (11) and recessed axially into said end face (17). At least one covering element (47) is arranged in the annular groove (45) and provides thermal shielding for the sealing element (31) at least on its side facing the end face (17) of the flange part (11).

  • Patent number: 8292301
    Abstract: A multifunction ring comprises an elastomeric body which totally encloses at least one circumferential tubular cavity filled with at least one liquid medium. In various ring embodiments the liquid medium conducts heat, damps vibration, blocks extrusion and/or transmits hydraulic pressure. When one or more rings are used in a plunger packing, longitudinal compression of the ring(s) secondary to increased pumped fluid pressure occurs during a pressure stroke. Such compression, acting through the compliance of each ring, increases tubular cavity hydraulic pressure and causes radial ring expansion. Ring expansion is both inward toward a plunger and, simultaneously, outward toward its packing box. Inward expansion tends to seal the extrusion gap, while outward expansion increases coupling from plunger to packing box to increase vibration damping and/or heat scavenging. Periodic reduction of pumped fluid pressure tends to reverse radial ring expansion, thus reducing both frictional ring wear and heat generation.

  • Patent number: 8276918
    Abstract: One or more multifunction elastomeric plunger seal rings augment a plunger packing assembly within a plunger pump packing box. Each such ring comprises a totally-enclosed circumferential tubular cavity. The cavity is filled with a dilatant liquid which transmits hydraulic pressure throughout the tubular cavity and simultaneously damps pump vibration transmitted via the packing box. Pump pressure strokes increase tubular cavity hydraulic pressure, resulting in radial ring expansion forces both inwardly toward a plunger and outwardly toward its packing box. Inward ring expansion tends to close the extrusion gap, while outward expansion force improves heat transfer from plunger to packing box. Outward expansion force also increases coupling of packing box vibration to hysteresis loss in the dilatant liquid.
