Abstract

PURPOSE: To coat even a curved pipe, a branched pipe, etc. with certainty, by filling a conduit with an expandable resin, by feeding a lining material between the resin and the inner wall surface of the conduit, followed by hardening.
CONSTITUTION: The conduit 1 is charged with an expandable resin (a) along the total length and hot air is supplied in the conduit 1 to foam the resin (a) and form the foamed plastic A. The fluid lining material B is fed under pressure in the space between the foamed plastic A and the inner wall surface of the conduit 1 and subjected to natural hardening. A high-temperature hot air is then supplied to melt and remove only the foamed resin A.
