Whether it is zinc lining or synthetic resin lining,
Considerable equipment and costs were required, and it was particularly technically difficult to uniformly apply anti-corrosion treatment to the entire inner surface of the long tube. In addition, synthetic resin pipes, whose body is formed by sequentially winding synthetic resin strips in a spiral shape, are lighter and easier to transport than metal pipes, and do not require corrosion-resistant treatment. However, it does not necessarily have sufficient strength to withstand tensile loads in the direction of the pipe axis, and there is a problem that it stretches in the direction of the pipe axis when high-pressure fluid is passed through it. Since they tend to lack crushing strength, they cannot necessarily be said to have sufficient strength for use in high-pressure fluids or for underground burial.

It has excellent crush resistance and flexibility, and can be bent extremely easily within a specified angle range, making it widely usable as pipes for high-pressure fluids such as liquid chemicals. The present invention also aims to provide a fluid pipe that can be easily formed into a curved pipe.

As the material for such metal strip 1a, steel plate, stainless steel plate, iron plate, or other metal plate may be arbitrarily selected depending on the purpose of the formed tube. As for the plate thickness, a thin plate having a thickness of approximately 0.3 to 3 mm is selected as appropriate, taking into consideration the diameter of the pipe to be molded, resistance to external pressure, resistance to internal pressure, purpose of use, location of use, etc. Further, the metal strip 1a is not limited to a flat plate, but may be a punched metal with a large number of small holes formed therein. Alternatively, a band material made of a large number of metal wires woven into a band-like net may also be used. Further, as the reinforcing wire material C, fibrous twisted yarns such as natural fibers or resin fibers, monofilaments, string-like or rope-like materials, bare metal wires, coated metal wires, etc. are used.

ある。<Effects of the invention> As detailed above in the description of the embodiments and as described in the section of means for solving the problems, the present invention uses ultra-thin membrane tape to cover the inner tube wall. It has a structure in which multiple layers are wound and polymerized, and all the layers are partially fused at predetermined intervals, and a hard material including a metal strip is formed on the outer peripheral surface of the inner tube wall formed in this way. The hard strip material is made into a special horizontal S-shaped strip structure, and its base portions are integrally abutted and fixed, and the free ends of adjacent hard strip materials are aligned in the axial direction and radial direction of the tube. Because the structure is arranged in such a way that they engage with each other,
By restricting the axial elongation of the tube so that it does not exceed a certain level, the tensile strength in the axial direction of the tube can be dramatically increased compared to conventional synthetic resin spiral tubes. Although the hard strips are extremely flexible and free within a certain range until they engage, the free ends of these adjacent hard strips will not engage with each other against bending forces at steep angles beyond a certain range. At the same time, the hard strip material, the reinforcing wire placed between them, and the hard wire buried within the inner pipe wall jointly counter the internal pressure, and resist the internal pressure from the outside. The compressive force of the tube can be counteracted by the hard outer tube wall, the tube is lightweight as a whole, and the inner tube wall has multiple layers, so the inner layer and outer layer can be made of different materials. This allows only the necessary inner layer to be made of a corrosion-resistant material suitable for the internal fluid, making it possible to obtain a durable fluid pipe that can be safely used as a fluid pipe for high-pressure fluids, chemicals, etc. In addition, since the hard strip material is manufactured in an S-shape with few corners, even when a flat strip material such as a metal plate is deformed and formed, the formation is easy. It also has the effect of being relatively easy to perform.
