A flexible shaft which has a plurality of metal sleeves having a smaller end portion and a larger end portion at opposite ends of the metal sleeve. One of the end portions has a plurality of protrusions whereas the other one has a plurality of apertures capable of accommodating a part of each of the plurality of protrusions. The smaller end portion of is partially inside the larger end portion of the next metal sleeve in the flexible shaft. Each metal sleeve is movably connected to the next metal sleeve using the protrusions and apertures. The apertures are notably larger than the protrusions in lengthwise direction of the flexible shaft which allows two adjacent metal sleeves to be in position where their rotation axes are not parallel.

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.

The invention relates generally to a system used to produce a prototype part and subsequently an accurate design specification for a fluid or gas handling system/hose and or tube assembly, followed by the subsequent communication of that specification into an ordering interface that processes the specification into a usable format as a means to accurately produce and re-create the original specification in a remote location by a specific manufacturing process, in order to supply the originator of the design an accurate, working part, produced in the specified materials in a rapid, convenient and cost effective manner. The process has global applications in various industries, markets and vehicle or machinery types, particularly where it is inconvenient or prohibitively expensive to have the work performed on-site by a technician.
