Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a flexible pipe made of a synthetic resin, smoothly circulating a fluid and having an inner peripheral surface which can be firmly fixed to an end of a pipe or the like made of a hard vinyl chloride resin by an adhesive by using a cut end part as a joint part even when the flexible pipe is cut arbitrarily, while forming a reinforcing material spirally on the inner peripheral surface thereof.SOLUTION: A belt-like reinforcing material 2 made of a hard vinyl chloride resin is buried spirally over the entire length on the inner peripheral surface of a flexible pipe body 1 made of a soft vinyl chloride resin, and an inner surface of the belt-like reinforcing material 2 is continuously flush with the inner peripheral surface of the flexible pipe body 1. The inner peripheral surface of the flexible pipe body 1 is formed in such a smooth surface that the fluid can smoothly flow over the entire length. The inner peripheral surface of the end part of the flexible pipe body 1 and the outer peripheral surface of the end of the pipe or the like made of the hard vinyl chloride resin are firmly fixed using the adhesive by the inner surface of the belt-like reinforcing material 2 exposed from the inner peripheral surface. |
