  • Patent number: 10385995
    Abstract: Described is a coupling seal that includes a polymeric body having a bore extending from a first end to an internal sealing surface and a fluid channel extending from the internal sealing surface to a second end. The bore is configured to receive a tube having a fluid channel so that an endface of the tube engages the internal sealing surface. The second end of the polymeric body is configured to contact a sealing surface of a coupling body that has a fluid channel extending from the sealing surface. A fluidic seal occurs when the coupling seal is compressed between the endface and the sealing surface. A void between an outer surface of the polymeric body and an inner surface of the coupling body receives the deformation of the coupling seal while under compression to thereby prevent the fluid channel of the tube from being crushed or obstructed.

  • Patent number: 9659112
    Abstract: There are provided a pipeline structure and a computer readable recording medium having recorded thereon a program that supports the design of the pipeline structure. The pipeline structure includes two collars and a plurality of short pipes. The plurality of short pipes are connected by joint structures. Two collars are arranged to sandwich a zone where a fault displacement is expected to occur, and thereby, a ground displacement in the pipe axis direction is dealt with (absorbed). The plurality of short pipes are connected by the larger number of joints than the number of joints in the case of arranging a long pipe. By increasing the number of joints, it becomes easier to deal with (absorb) a ground displacement in the direction perpendicular to a pipe axis.

    Abstract: A fitting element (100), in particular for an HPLC application (10), is configured for providing a fluidic coupling of a tubing (102) to a fluidic device (103). The fitting element (100) comprises a gripping piece (108) to exert—upon coupling of the tubing (102) to the fluidic device (103)—a grip force (G) between the fitting element (100) and the tubing (102). The gripping piece (108) comprises a hydraulic element (170) configured to transform an axial force (S) into a hydraulic pressure (P) within the hydraulic element (170). The hydraulic pressure (P) in the hydraulic element (170) causes the grip force (G).

  • Patent number: 8444187
    Abstract: A separation prevention device for a pipe joint has disengagement prevention members and a press member. The disengagement prevention members are disposed at a plurality of locations in a circumferential direction of the pipe, on an inner peripheral surface of an engaging tool or of a receiving opening itself and which are formed with claws. The press member presses the disengagement prevention member radially inward of the pipe and which engages the claw with the outer peripheral surface of an inserting opening. The claw of the disengagement prevention member and the claw of the disengagement prevention member which is adjacent to the former disengagement prevention member in the circumferential direction of the pipe are arranged so as to overlap on each other in the axial direction of the pipe in a state where the claws are engaged with the outer peripheral surface of the inserting opening.

  • Patent number: 8439407
    Abstract: A fitting for a tube or pipe capable of functioning a high pressures having a first fitting component adapted to receive the conduit end; a conduit gripping device such as a ferrule or ferrules and a second fitting component that can be joined to the first fitting component to cause the conduit gripping device to grip the conduit and seal when assembled. In one aspect of the invention, the first fitting component is constructed from a material that is softer than the material used to construct the second fitting component. An additional aspect of the invention include a retaining portion on the second fitting component that constrains the tube gripping device against pressure. The retaining portion can also be configured to retain the tube gripping device to the second fitting component prior to installation and in a finger-tight condition.

  • Patent number: 8371621
    Abstract: A fitting connection for a capillary has a sealing bushing, a compression bushing, and a backing bushing. The backing bushing has a bore for receiving the sealing bushing and the compression bushing into the backing bushing, and the sealing bushing and the compression bushing are each provided with a central bore for feeding through a capillary tube. The bore of the backing bushing has a partly slightly conical bore end which compacts the sealing bushing such that the bore of the sealing bushing exerts a radial surface pressure onto the external wall of the capillary.

    Abstract: A tube fitting for sealing an end of a tube uses a notch formed in the exterior surface of the tube as a sealing seat. An internally threaded body is configured to receive an externally threaded end of a nut, while the body and the nut are mounted in a surrounding relationship to the tube end. A ferrule mounted between the nut and the tube is forced to plastically deform and move into the notch to thereby seal the tube end.

  • Patent number: 8272671
    Abstract: A connector connects the ends of two fluid lines, it is useful for connecting and sealing the ends of refrigerant lines in an automotive air conditioner. A resilient seal is disposed about the end of a fluid line within each end of the passageway and a combination slotted ferrule and sealing ring member formed with a sealing ring portion and a ferrule portion is captured between the seal and a compression nut treaded onto the end of the body. When the nut is tightened onto the end, it causes the ferrule portion to deform and collapse inwardly to grasp and hold the fluid line securely in place and simultaneously drives the sealing ring portion against the seal to compress the seal, which expands to form a fluid-tight seal around the end of the fluid line.
