Abstract
PURPOSE: To prevent slacks or wrinkles from occurring in a resin pipe by a method wherein synthetic resin is inserted into a metal pipe fitted up with concaved or convexed grooves on the inner circumferential surface thereof and the resin pipe is heated, softened and then expanded.
CONSTITUTION: On the inner circumferential surface of a metal pipe 1 fitted up with flanges 11 on either end are provided multiple concaved or convexed grooves 12 which continue from one end to the other. Into this pipe 1 is inserted a synthetic resin pipe 2, on the outer circumferential surface of which adhesives have been coated previously, its both ends are flanged at the flange faces of ends-supporting pipes 3 and put between the supporting pipes 3 and ducts 5, clamped and fixed. Then, heat medium is interoduced from one duct 5, the resin pipe 2 is heated, softened, then pressure liquid is introduced from the duct 5, the air between the inner circumferential surface of the pipe 1 and the outer circumferential surface of the resin pipe 2 is exhausted through air holes 41 fitted up in the concaved or convexed grooves 12, spacers 4 and the resin pipe 2 are allowed to expand until its outer circumferential surface sticks to the inner circumferential surface of the pipe 1.
