<p>PROBLEM TO BE SOLVED: To easily separate a resin coated part from a metal-made pipe at the time of discarding. SOLUTION: A coated pipe is constituted by providing a linear thin wall part 4a to a resin-coated part 3 of the coated pipe 1 wherein synthetic resin is coated on a metal-made pipe 2, or containing a linear body. Since the resin- coated part 3 easily tears along the linear thin wall part 4a, and when the linear body is pulled, the resin coated part 3 is cut, the resin-coated part 3 can be easily separated by being peeled off from the metal-made pipe 3.</p> |
