  • Patent number: 11846374
    Abstract: A pipe joint with a socket, and a pipe fitted into the socket. An annular seal is compressed between the socket and the pipe. The seal is electrically conductive and resiliently flexible. The socket or the pipe has a recess which houses the seal. The recess has a ridge in a base of the recess and the seal has a groove which extends around a radial periphery of the seal. The ridge fits into the groove to fool proof the installation, such that a standard non-conductive O-ring seal is more difficult to install in error.

    Abstract: Provided herein is a liner that can be loosely inserted in process pipe to form a lined pipe and to decrease the rate of heat transfer between process fluids flowing through the liner and the process pipe. The liner provided herein can reduce applied thermal loading on the outer pipe resulting from, for example, turbulent mixing between fluids having different temperatures (with or without stratification), circumferential thermal gradients, and/or longitudinal thermal gradients. An annulus between the process pipe and liner can be at least partially filled by process fluids, thereby creating a thermal buffer to further decrease the rate of heat transfer between the fluids and the process pipe.

    Abstract: A tube is surrounded by a ring attached to a sleeve. One end of the tube is attached to a pipe of the pipeline, one end of the sleeve is attached to another pipe of the pipe line. The tube and the ring and sleeve are movable axially relatively to one another when the pipe line expands or contracts linearly. A seal between the ring and the tube ensures fluid tightness of the joint.

  • Patent number: 9551443
    Abstract: A vehicle fluid line for transporting high and low pressure fluids of an engine includes a rigid pipe having opposing ends configured to fixedly couple with the engine. An adjustable joint divides a length of the rigid tube into first and second segments. The adjustable joint has a cylindrical housing coupled with the first segment and having an inner diameter. A stop feature protrudes from an outer diameter of the second segment and interfaces with the cylindrical housing to prevent disengagement of the second segment from the housing. An elastomeric grommet is seated between the inner and outer diameters and is configured to maintain a fluid seal that allows the second segment to rotate axially, pivot radially, and slide longitudinally within the cylindrical housing.

  • Patent number: 9279384
    Abstract: A sealing system comprising a cylinder head, a coupler, a fuel injector line, a seal retainer, and a seal. The coupler is positioned in the cylinder head, and the fuel injector line extends into the coupler so as to at least partially define a fuel leak passageway therebetween. The seal retainer yieldably urges the seal towards a seated position in which the seal established a sealed connection between the fuel injector line and the coupler, so as to block ingress of moisture into the fuel leak passageway. Further, the seal retainer allows movement of the seal away from the seated position to an unseated position in which the sealed connection between the fuel injector line and the coupler is broken in response to pressurized leaked fuel, in the fuel leak passageway, so as to allow the pressurized leaked fuel to flow out of the fuel leak passageway.
