Abstract
PURPOSE: To obtain a substrate best fitted for a reversal insertion method, whose outer diameter is a little smaller than the inner diameter of a conduit and expands in a specified quantity when the pressure equal to the minimum fluid pressure at the reversal insertion is applied to the inside thereof.
CONSTITUTION: A substrate 1 is made by forming a skin film 8 of soft rubber or plastic on the outer surface, at least, of a tubelike cloth 7 woven with fibers. The substrate 1 is inserted in and pressed against the inside of a conduit 2, being reversed so that the inside thereof is turned outside by the fluid pressure, thus used for lining inside the conduit. The substrate 1 is made so that its outer diameter is a little smaller than the inner diameter of the conduit 2 and expands by 7W15% when the pressure equal to the minimum fluid pressure at reversal insertion is applied to the inside thereof, thus the possible occurrence of a vacant place between the substrate and the inner surface of the conduit in the middle of the conduit is prevented.
