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 connector including a stem portion inserted into a distal end of the inner core tube, an outer metal tube substantially coaxial with and surrounding the inner core tube, and a collar substantially coaxial with and surrounding the distal end of the inner core tube. The outer metal tube terminates at a distal end axially inward of the distal end of the inner core tube. The collar includes a flared first end welded to the distal end of the outer metal tube and a second end welded to the connector.

Device for a double hose structure with an inner main hose and an outer cover hose defining an annular space giving buoyancy in water. At least one end is provided with a coupling member forming a mount for the main hose and the cover hose which at a free end merges into a threaded portion for connecting the hose assembly to an auxiliary connection. The coupling member comprises an inner coupling sleeve connected to one end of the main hose and an outer coupling sleeve connected to the cover hose, the inner and outer coupling sleeves being mutually connected forming a liquid tight termination of the annulus by a ring-shaped plate. The plate is attached with screws through holes only to the outer sleeve, the plate being forced against a shoulder of the inner coupling sleeve by a ring nut with internal threads matching external threads on the inner sleeve.

An expandable and contractible hose, the hose includes a segmented tubular wall circumscribing an interior. The segmented tubular wall is made up of a plurality of contiguous segments. Each contiguous segment expands along the length of the hose with the application of pressure from within. A bias holds the contiguous segments in a collapsed state when no pressure is applied from within the interior. A pressurized fluid passing within the interior overcomes the bias and causes the contiguous segments to expand into an expanded state.

A hose assembly is provided having a bendable inner hose, a bendable outer hose, and a ferrule, wherein both the inner and outer hose are connected to the ferrule.

A hose connector (5) which can be fixed to the hose end region of a flexible hose (6) and includes an outer part (7), which surrounds the hose end region, and an inner part (8), which can be inserted into the clear cross section of the hose. The inner part (8) is in the form of a hollow rivet and is deformable between an initial form, which can be inserted into the clear cross section of the hose at the hose end region, and a widened form, which sealingly and fixedly clamps the at least one hose between the inner part (8) and the outer part (7). A hose line that can also be formed for example as a two-chamber or multi-chamber hose line is provided. Moreover, a method for producing a hose connector on the hose end region of a flexible hose is provided.
