Abstract

Provided is a pipeline renewal pipe which can be smoothly inserted in an existing pipeline having a bent portion, and in addition can prevent damage during insertion into the existing pipeline and increases in pressure loss during fluid transportation. A pipeline renewal pipe (1) is formed by spirally winding a reinforcement core (3), which is made of a hard resin, around the outer circumferential surface of a pipe main body (2) which is made of a soft resin. The pipeline renewal pipe (1) is flexible enough to be able to be inserted in an existing pipeline (10) while the pipeline renewal pipe (1) is bent so as to follow a bent portion (15) of the existing pipeline (10). Therefore, when the pipeline renewal pipe (1) is bent, a pipe wall part (4) positioned between the reinforcement cores (3, 3) of the pipe main body (2) can be folded so as to protrude radially outward. A maximum protrusion dimension (L3) in the radially outward direction of the folded pipe wall part (4) is made to be smaller than a protrusion dimension (L2) in the radially outward direction of the reinforcement core (3) to thereby prevent the folded pipe wall part (4) from protruding radially outward more than the reinforcement core (3) of the folded pipe wall part (4).
