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.

A connector assembly (608) for a length of corrugated tubing (601) having an inner corrugated element (602) and an outer flexible sheath layer (603). The connector assembly (608) comprises a fitting (609) including a fluid-flow passage and an abutment surface (612) for the corrugated tubing (601) to seat thereon; axial loading means operably connectable to the fitting (609), the axial loading means including a connector (613) and a collet (610), the collet (610) having a radially inward protruding clamping element (611) for insertion into a trough (606) of the inner corrugated element (602), and a sheath-contact portion (625) for engaging the outer sheath layer (603), so that, when the connector (613) moves the collet (610) into engagement with the fitting (609), the collet (610) causes the corrugated element (602) to move onto the abutment surface (612) whilst maintaining engagement with the outer sheath layer (603). The sheath-contact portion (625) is axially positionable between the inner corrugated element (602) and the outer sheath layer (603) of the corrugated tubing (601), in use.

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.

Techniques for implementing and/or operating a pipeline system that includes a pipe segment and a reusable pipe fitting. The pipe segment includes tubing that defines a pipe bore and a fluid conduit within a tubing annulus of the pipe segment. The reusable pipe fitting includes a fitting body that defines a body bore and a pipe engaging assembly including a collapsible collar with teeth that extend radially inward. The collapsible collar contracts radially inward such that the collapsible collar engages the tubing of the pipe segment to facilitate securing the reusable pipe fitting to the pipe segment when the pipe engaging assembly is secured to the fitting body and expands radially outward such that the collapsible collar disengages from the tubing of the pipe segment to enable the reusable pipe fitting to be re-deployed at another pipe segment when the pipe engaging assembly is unsecured from the fitting body.
