A hydraulic coupling system is configured to couple a hydraulic hose to a hydraulic cylinder and includes: a compressive adapter assembly including: a first adapter portion configured to receive a portion of the hydraulic hose, and a second adapter portion configured to engage an inlet tube of the hydraulic cylinder, wherein a first tube portion of the inlet tube of the hydraulic cylinder is configured to be received within a portion of the hydraulic hose; and a compressive sleeve assembly configured to engage the compressive adapter assembly and radially compress the first adapter portion of the compressive adapter assembly onto an outer surface of the portion of the hydraulic hose, thus compressing an inner surface of the portion of the hydraulic hose onto the first tube portion of the inlet tube of the hydraulic cylinder.

A hose construction having a coupling secured to an end of a hose, with the coupling including a tubular insert formed with a polymer mixed with chopped reinforcement fiber and including first and second ends, with the first end being inserted in the hose, and the second end including a connector interface. A tubular metallic ferrule is connected to the tubular insert adjacent to the second end in order to form an annular hose receiving space between an outer surface of the insert and an inner surface of the ferrule. The end of the hose is received in the annular hose receiving space, and the ferrule is deformed inwardly against the hose to form a secure connection. The tubular insert formed of a non-metallic material has high strength and is resistant to corrosion due to contact with the materials being transported.

An improved end connector for a high-pressure reinforced hose that is subjected to high frequency of pressure cycles and that provides for a low compression deformation of the reinforced hose is discussed. This unique end connector has a stem and ferrule that includes a gripper or cable lock region near a coupler, or outboard end and a substantially smooth length on an outer diameter (OD) of the stem and ferrule that extends from about the gripper region to a hose receiving, or inboard, end.

Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment and a swage machine. The pipe fitting includes a fitting jacket to be conformally deformed around tubing of the pipe segment. The swage machine includes a grab plate that interlocks with the pipe fitting, a die plate, in which a die is to be loaded in the die plate, a swaging actuator secured to the die plate, in which the swaging actuator facilitates conformally deforming the fitting jacket around the tubing of the pipe segment by causing the die plate and the grab plate of the swage machine to move toward one another, and a die retainer actuator secured to the grab plate of the swage machine, in which the die retainer actuator extends through the grab plate toward the die plate and pushes against the die.

A swage fitted end connector for high pressure large diameter reinforced flexible rubber hose utilizing sine-wave locking of the reinforcement and particularly suited to the petrochemical and drilling industries. Two embodiments of the connector for use with wire reinforced thin internal tube hose are disclosed: one with a diameter of 3-inches and for burst pressures up to 20,000 psi and the other for a diameter of 5-inches and for burst pressures up to 18,000 psi. All of the connectors will withstand the rated burst pressure of the hose without pumping off or leaking thus any hose that utilizes the device will fail before the connector pops off the hose. The connectors are designed to meet or exceed the new API temperature ranges and new API flexible specification levels which became effective in October 2006.

The invention relates to a fitting provided on the end of a pressurized hose or pipe. The invention provides a fitting having a spigot and a ferrule part in which opposing recess and projecting parts are provided to engage each other and prevent the two parts unwinding from each other.

A system includes a flexible pipe that includes a liner surrounding a bore of the flexible pipe, a reinforcement layer surrounding the liner, and a shield layer surrounding the reinforcement layer. The system also includes a pipe fitting coupled to an end of the flexible pipe and a securing mechanism at least partially disposed in an opening in at least one of the liner layer, the shield layer, or both of the flexible pipe. The securing mechanism is configured to engage with the reinforcement layer of the flexible pipe when the pipe fitting is coupled to the end of the flexible pipe.

A hose adapter may include an outer tube, an inner tube, a hose connector, and a hose. An inner peripheral ring protrudes from the inner periphery of the outer tube while an expanding ring portion protrudes from the outer periphery of an end of the inner tube. The outer periphery of the inner tube further has a first peripheral recess, a second peripheral recess, and a first outer thread, and a first O-ring and a second O-ring are respectively disposed on the first peripheral recess and the second peripheral recess. The inner tube is inserted into the outer tube, and the expanding ring portion is abutted against the inner peripheral ring, and the first O-ring is coupled between the outer tube and the inner tube while the second O-ring and the first outer thread are adapted to pass through and be exposed out of the outer tube.

A universal device for replacing worn or lacerated parts of connecting conduits between components of climate control or cooling or hydraulic systems for the connection between components of new climate control or cooling or hydraulic systems, comprising a metal sleeve provided at an end of a coupling for pipes joined to it in a sealed fashion, designed to be fitted and clamped on a stretch of rigid pipe joined to a connector for connection of the connecting conduit to a component, and at the other end of a fitting for connection with a flexible hose designed to replace the worn or lacerated connecting conduit. The sleeve can be rectilinear or curved with angle of approximately 45 or approximately 90. The previous device is prepared in a kit according to different sizes.

Techniques for implementing a pipeline system that includes one or more pipe segments, in which each pipe segment of the one or more pipe segments includes tubing that defines a pipe bore and a fluid conduit implemented in an annulus of the tubing, and a re-deployable pipe fitting to be secured to the one or more pipe segments. The re-deployable pipe fitting includes a fitting body that defines a fitting bore through the re-deployable pipe fitting and a threaded fitting jacket to be deformed around the tubing of a pipe segment of the one or more pipe segments to facilitate securing the re-deployable pipe fitting to the pipe segment. The threaded fitting jacket includes jacket threading that enables the threaded fitting jacket to be coupled to the fitting body, removed from the fitting body, or both without using hot tooling.
