Abstract
PURPOSE: To form a coating film readily on the inner wall of a metallic tube with a simple equipment by a method wherein a thin thermoplastic synthetic resin sack body of cylindrical shape is inserted along the inner wall of the metallic tube to its axial direction, heated and fused at the fusing point exceeding that of the above- mentioned sack material.
CONSTITUTION: A thin thermoplastic synthetic resin sack 3 is inserted in the axial direction of a metallic tube 1 and in contact with the inner wall surface 2 of the metallic tube 1 and the outer circumference 4 is stuck on the inner wall surface 2. Under such contact they are heated and fused at the fusing point of the thin thermoplastic resin sack material or at higher temperatures in a heating device and then cooled and cured. For instance, a STPG35 metallic tube is used for the metallic tube 1 and a sack of polyethylene resin or polypropylene resin which has been stuck on a guide core is inserted into the inner wall of the metallic tube. Then they are placed in an induction heating furnace, heated and fused at 230°C there, cooled and cured and resin coat is formed on the inner wall surface of the metallic tube.
