Techniques for implementing a system that includes pipe segment tubing and a pipe fitting to be secured to the pipe segment tubing. The pipe segment tubing includes a reinforcement strip implemented between an internal pressure sheath layer and an outer sheath of the pipe segment tubing. The pipe fitting includes an inner fitting body to be inserted between the internal pressure sheath layer and the reinforcement strip of the pipe segment tubing. Additionally, the pipe fitting includes an outer fitting body to be disposed circumferentially around the inner fitting body to define a potting cavity between an inner surface of the outer fitting body and an outer surface of the inner fitting body, in which a hole is formed through the reinforcement strip of the pipe segment tubing before the reinforcement strip is anchored in the potting cavity via cured potting material.

A hose assembly includes an inner core tube, a metal outer tube, a first coupling member, and a first collar. The first coupling member has an inboard nose portion extending into a first end of the inner core tube. The metal outer tube surrounds the inner core tube and terminates at a first end axially inward of the first end of the inner core tube, with an outer cavity disposed between the inner core tube and the metal outer tube. The first collar has an outboard clamping portion surrounding the nose portion for clamping retention of the first end of the inner core tube therebetween, and an inboard venting portion welded to the first end of the metal outer tube, with the inboard venting portion including a venting port in fluid communication with the outer cavity.

A method and apparatus for securing a flexible pipe to a further flexible pipe in an end-to-end configuration, wherein the apparatus includes and the method utilizes an elongate tubular element having a first and second end and an outer surface comprising a raised central region. At least one vent passage extends at least partially across the raised central region.

A hose assembly includes a corrugated metal tube having a plurality of corrugations and an outer cuff portion extending from an endmost one of the plurality of corrugations, radially outward of an inner diameter of the endmost corrugation, an end connection having an outer end defining a fluid connector and an inner end defining a nose portion received in the outer cuff portion of the corrugated metal tube, and a collar surrounding the outer cuff portion of the corrugated metal tube and the nose portion of the end connection. The collar, the outer cuff portion, and the nose portion are welded together.

A hose which automatically expands longitudinally and automatically expands laterally upon the application of a pressurized liquid is disclosed. The hose can automatically expand longitudinally up to six times its unexpanded or contracted length. Upon release of the pressurized liquid within the hose, the hose will automatically contract to a contracted condition. The hose includes an inner tube made from an elastic material and an outer tube made from a non-elastic material. The inner tube is positioned concentrically within the outer tube in both a contracted condition and an expanded condition. The outer tube is secured to the inner tube only at a first end of the inner and outer tubes and at a second end of the inner and outer tubes. The outer tube moves laterally and longitudinally with respect to the inner tube when the tubes are transitioning between a contracted condition and an expanded condition.

Techniques for implementing and/or installing a system including pipe segment tubing and a swaged pipe fitting secured to the pipe segment tubing. The pipe segment tubing includes a carcass layer, an internal pressure sheath layer disposed around the carcass layer, a reinforcement layer disposed around the internal pressure sheath layer, and an outer sheath layer disposed around the reinforcement layer. The swaged pipe fitting includes a fitting body that defines a bore, an internal pressure sheath seal that seals the internal pressure sheath layer of the pipe segment tubing within the swaged pipe fitting, and a fitting jacket secured to the fitting body, in which the fitting jacket is conformally deformed around the pipe segment tubing to anchor the reinforcement layer of the pipe segment tubing in the swaged pipe fitting.
