A multi-layer pressure actuated extendable hose for use in transporting fluids between a source location and an output location includes an extendible hose comprising a biasing element, a sealing layer, and a reinforced cover layer. The sealing layer forms a sealed conduit for transporting the fluids, and the reinforced cover layer on the outside provides radial and longitudinal strength for the sealing layer. The hose can be operated by increasing internal pressure within the hose relative to ambient pressure. When the hose is pressurized by a fluid source, the internal pressure of the hose overcomes the retracting force of the biasing element and the hose extends. When the fluid source is turned off or disconnected from the hose, internal pressure is reduced and the biasing element exerts a tension force on the hose causing the hose to retract.

The invention provides a cross-linked fluororesin having excellent abrasion resistance against metal. The cross-linked fluororesin is obtainable by cross-linking a fluororesin. The fluororesin contains a tetrafluoroethylene unit and a vinylidene fluoride unit, and the tetrafluoroethylene unit represents 50.0 mol % or more of all the monomer units constituting the fluororesin.

Methods and systems are disclosed for onsite real-time manufacturing of any length, shape, size, and any thickness pipe. Strips of fabrics saturated with resin are helically wrapped around desired shape mandrels in one direction and removed, at least partially cured, to form such pipes onsite. The system can be mounted on a moving vehicle to manufacture and lay down any length pipe as it moves, or the system can be stationary. Disclosed pipes eliminate almost all weaknesses of plastic, metal and concrete pipes and noticeably reduce costs of transportation as well as manufacturing. One of the advantages of the disclosed pipes is that they have no joints, limiting the leakage and other problems associated with joints in ordinary pipes. Another advantage of the disclosed pipes is that it can have any number of desired layers at any desire cross-section of the pipe.

The invention relates to a flexible pipe carcass comprising a flexible tubular wall structure comprising a helically wound wall strip; wherein interlocking sections of successive windings of said wall strip form the wall structure. The interlocking sections of adjacent wall strips define a length and are movable with respect to each other between a first position and a second, extended position for changing said length, the interlocking sections being formed such that in the extended position a carcass gap is provided between adjacent interlocking sections for accommodating relative movement there between upon flexure of the wall structure. An insert profile is located in the carcass gap of the tubular wall structure on an inside of the wall structure to at least partly cover the carcass gap.
