  • Patent number: 9188260
    Abstract: An O-ring has a flange which includes a plurality of slots, such that, when inserted into an annular groove of a pipe fitting before crimping, the slots allow the flow of fluid therethrough, such that an installation would not pass pressure tests until such time as a proper crimp has been made. Such a design allows the use of conventional push-on pipe connections by utilizing a unique O-ring seal which works in conjunction with standard push-on crimp-type pipe fittings and conventional crimping tools for subsequently sealing the connection. The O-ring is either circular or elliptical in cross section and the slots define equally spaced annular segments.

  • Publication number: 20150076817
    Abstract: A composite sliding gasket for joints of high-pressure pipes is basically formed by a rubber part and by a rigid ring—having the function of flange—that is designed to draw the gasket itself from a resting position or seat to a working position or seat by an external pipe or hole that is axially fitted on an internal pipe or barbed fitting. Compression of the rubber part of the gasket, which guarantees fluid tightness, is obtained thanks to the presence of a purposely provided conical area pre-arranged on the barbed fitting between the resting seat and the working seat. The gasket includes a rubber ring fixedly coupled to a coaxial flange made of rigid material of plastic or metal or other suitable material, the gasket being designed to seal a coupling with play between the internal pipe and the hole within which a pressurized fluid can flow.

  • Patent number: 8475139
    Abstract: A method and apparatus for a Boiling Water Reactor (BWR) jet pump slip joint internal seal for an interface between an inlet mixer and a diffuser of a jet pump assembly. The internal seal effectively mitigates leakage and slip joint flow induced vibration (FIV) between the inlet mixer and diffuser to reduce damage to many of the jet pump assembly components. A metallic seal of the slip joint internal seal flares out to conform the internal seal to a range of gap sizes, and compresses or springs back to nominal dimensions as thermal expansion and contraction occurs. The internal seal is self-expanding/self-tightening, as the internal seal flares further outward as a result of the internal pressure caused by flowing fluids in an operating jet pump assembly.

  • Publication number: 20130153046
    Abstract: A fuel line assembly for an aircraft comprises a ferrule assembly comprising a ferrule affixed to an isolation tube, which may be directly affixed to a fuel tube or affixed to an extension tube, which in turn, is affixed to the fuel tube. The ferrule assembly provides electrostatic discharge protection and lightning protection as the isolation tube maintains a separation distance from the ferrule and fuel tube, both of which are made from metal. The isolation tube is made from a dielectric material, but which may have conductive particles added to aid in the dissipation of an electrostatic charge. The electrical resistance through the isolation tube has a lower limit to arrest the flow of the induced lightning current through the assembly. The amount of lightning protection afforded can be configured. The ferrule assembly components may be affixed by using thermo-welding, adhesive, or mechanical pressure.

  • Publication number: 20130140813
    Abstract: A subsea riser assembly connects two tubular members with axial movement of an outer sleeve. The assembly includes a first tubular member having an end, and a second tubular member having an end with a plurality of box end fingers separated by slots, the second tubular member coaxial with the first tubular member. The end of the first tubular member is inserted into the end of the second tubular member. An outer sleeve having an inner diameter that engages an outer diameter of each box end finger. Axial movement of the outer sleeve relative to the box end fingers causes the inner diameter of the outer sleeve to interact with the outer diameter of the box end fingers, thereby causing the box end fingers to contract radially. The radial contraction of the box end fingers secures the first tubular member to the second tubular member in a made-up position.
