The present invention discloses an extensible flexible hose comprise one elastic inner layer, one elastic textile reinforcement layer and one elastic outer layer, where the elastic textile reinforcement layer placed on the outer surface of the elastic inner layer, the elastic outer layer disposed on the elastic textile reinforcement layer, while the elastic inner layer and the elastic textile reinforcement layer are reciprocally coupled, the elastic outer layer and the uncovered surface area of the elastic inner layer are reciprocally joined to form a unitary tubular member. The elastic textile reinforcement layer comprising a twill weave textile layer, with stretch yarns longitudinally distributed among. The objective of the present invention is to improve the phenomenon that the telescopic water pipe is liable to be damaged due to strong friction between inner core and outer sheath, to prolong the service life of the extensible flexible hose. The hose body adopts elastic materials, which has advantages as great elasticity, easy carrying, easy cleaning, and convenient storage.

A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.

A method of applying protective sheeting of polymer material to a pipeline, such as on a J-lay rig, includes the steps of driving a carriage along an annular path about the pipeline; extruding and simultaneously winding the protective sheeting about the pipeline via an end extrusion die fitted to the carriage; compressing the protective sheeting on the pipeline, directly downstream from the end extrusion die, so the protective sheeting adheres to the pipeline; and controlling the drive, extrusion, and compression steps so that the time lapse between expulsion of a cross section of protective sheeting from the end extrusion die and compression of the same cross section of protective sheeting is less than one second.

A nonmetallic flexible pipe and a manufacturing method thereof. The nonmetallic flexible pipe comprises, from the inside to the outside, an inner liner, a pressure bearing layer, an isolation layer, a tensile layer, a functional layer, and a protective layer, wherein two adjacent layers are non-rigidly bonded. The inner liner layer is made from a thermoplastic polymer. The pressure bearing layer is made from a fiber-reinforced resin-based composite material. The isolation layer is made from a thermoplastic polymer. The tensile layer is made from a resin-reinforced fiber material. At least one of an optical fiber, a cable, a tracing ribbon, a pipe for conveying a heat transfer medium, a pressure sensor, and a temperature sensor is provided in the functional layer. The protective layer is made from a thermoplastic polymer.

A method of manufacturing a clipless package for an elongate medical device or other elongate device is provided. The subject invention utilizes adhesives and material surface characteristic modification to bond the tube surfaces together, which overcomes the deficiencies of currently utilized packaging methods. The bonds can be created by a singular application of adhesive or in plurality or combination with a surface modifier, coated surface and/or a surface treatment, or by selection of a singular polymer outer layer that is tacky when fully cooled, whose morphology changes post-extrusion.
