  • Patent number: 12241569
    Abstract: An installation apparatus for connecting a fluid fitting to a fluid element includes a tool mechanism having a first abutment surface and a second abutment surface that faces and is movable relative to the first abutment surface; a first sensor configured to detect a first property of the installation apparatus or fluid fitting and provide a first output corresponding to the first property; a second sensor configured to detect a second property of the installation apparatus or fluid fitting and provide a second output corresponding to the second property; and a processing unit that is configured to generate a first resulting data set based on the first output and second output, and compare the resulting data set with a first predetermined data set to determine if the first resulting data set is compliant with the first predetermined data set.

  • Publication number: 20230204439
    Abstract: A sensor device is provided for attachment to a surface of a fluid fitting, including a sensor portion comprising a sensor configured for detecting a physical parameter, a flexible circuit portion comprising a flexible circuit board and one or more circuit components supported by the flexible circuit board, and a rigid circuit portion comprising a rigid circuit board and one or more other circuit components by the circuit board. The sensor portion, flexible circuit portion, and rigid circuit portion are operatively coupled together and adapted to be affixed to said surface of said fluid fitting. In one example, a strain sensor is used. In another example, the fluid fitting comprises a coupling body defining a bore for receiving said fluid element therein. A ring is configured to fit over at least one end of the coupling body for mechanically attaching the coupling body to said fluid element.

  • Publication number: 20210332918
    Abstract: A fluid system includes a fluid fitting for mechanical attachment to a fluid element. The fluid fitting includes a coupling body having an inner surface defining a bore for receiving the fluid element therein, and a seal portion formed on the inner surface for engaging the fluid element. The fluid fitting further includes a ring configured to fit over at least one end of the coupling body. When the ring is installed on the coupling body via force with the fluid element received in the bore, the ring applies a compressive force to the coupling body sufficient to cause permanent deformation of the coupling body such that a tooth of the seal portion bites into the fluid element to thereby attach the fluid element to the coupling body in a non-leaking manner. Moreover, at least one of the fluid element, the coupling body, and the ring includes duplex stainless steel.

  • Patent number: 9278441
    Abstract: A hydraulic installation tool comprises a fixed jaw, a movable, and a plurality of independent hydraulic cylinders each comprising a piston. Movement of the pistons in a first direction moves the movable jaw toward the fixed jaw. A plurality of guide rods comprises a first end secured to the fixed jaw. A plurality of retaining members are each removably coupled to an associated one of the plurality of guide rods about the second end. The movable jaw is disposed between the fixed jaw and the plurality of hydraulic cylinders for movement along the guide rods. Each hydraulic cylinder is independently removable from the associated guide rod upon removal of the associated retaining member from said guide rod. In one example, the fixed and movable jaws are configured to engage and axially force a swage ring onto a fitting body to connect and seal the fitting body to a fluid conduit.

  • Patent number: 8870237
    Abstract: A fitting for coupling with a pipe in a sour environment includes a coupling body, a ring positioned to fit over an end of the coupling body, a main seal formed on an inner surface of the coupling body, a transition section positioned adjacent the main seal, an inboard seal formed on an inner surface of the coupling body, and an outboard seal formed on an inner surface of the coupling body. The transition section is formed as an indentation on the inner surface of the coupling body and has a first portion with a first diameter and a second portion with a second diameter, with the first diameter being greater than the second diameter. When the ring is fitted over the at least one end of the coupling body via force, the ring and coupling body apply a coupling force to the main seal, the outboard seal and the inboard seal to connect the pipe to the coupling body in a non-leaking manner. The fitting is made of a low alloy carbon steel material. The main seal includes a first seal, a second seal, and a third seal.
