What is done
The embodiment will be described with reference to the drawings. Reference numeral 1 denotes a resin conduit provided at a central portion of a water supply pipe, which is formed by extrusion molding of high-density polyethylene. It is spirally wound and fixed, and the reinforcing steel strip 3 is spirally wound around the outer periphery and fixed similarly. The reinforcing steel strip 3 is formed in a plurality of layers as necessary. A linear low-density polyethylene layer 4 for corrosion protection is formed by extrusion on the outside of the reinforcing steel strip 3 spirally wound in this manner.

層４の被覆を最も簡単容易に行ないうる効果がある。Conventionally known steel pipes and cast iron pipes are heavy in weight, are subject to freezing, are inconvenient to handle, and are expensive. However, the present invention provides a resin conduit 1 made of high-density polyethylene formed by extrusion and provided at a central portion, and a cushioning cloth tape 2 helically tightly wound around the resin conduit 1 and fixed. And a reinforcing steel strip 3 tightly wound around the outer periphery of the cushioning cloth tape 2 in a tightly wound manner, and a linear low-density anticorrosion formed by extrusion on the outer circumference of the reinforcing steel strip 3. Since this is a water supply pipe composed of a polyethylene layer 4, a high-density polyethylene resin conduit 1 formed by extrusion molding is provided at the center and water is supplied by this.
It is lighter and cheaper than a cast pipe, and is easy to handle because it can be easily bent. The reinforcing steel strip 3 is wound around the outer circumference of the resinous pipe 1 via the cushioning cloth tape 2 spirally wound. Since the reinforcing steel strip 3 is wound and bent, the important resin conduit 1 is not damaged, and the winding of the reinforcing steel strip 3 makes the entire pipe robust, and the reinforcing steel strip 3 Since the linear low-density polyethylene layer 4 for anticorrosion is provided on the outer periphery, it is extremely resistant to abrasion, and is extremely resistant to cold compared to other materials. Even if it is laid by bending, the occurrence of cracks is very small. In addition, since the anticorrosion linear low-density polyethylene layer 4 is provided on the outer periphery of the reinforcing steel strip 3 by extrusion molding, the most difficult coating of the anticorrosion linear low-density polyethylene layer 4 is most easily and easily performed. Has an effect.
