Abstract

PURPOSE: To provide the subject method of inserting a cylindrical thermoplastic synthetic film into a metal tube to bond the film to the metal tube thereby to apply the inner surface coat free of pinholes by an easy operation.
CONSTITUTION: A film made of a thermoplastic synthetic resin (such as polyester, polyamide, polyacryl, polycarbonate, polyolefin or polyvinyl chloride series) is rounded (wound in several rounds) ln a cylindrical shape, and inserted into a metal tube. The film is caused to tightly adhere to the inner face of the metal tube, and heated (it is preferable to gradually heat the metal tube from the outer surface or inner surface by providing a temperature gradient from one end to another by means of electrical heating, infrared ray heating, high frequency induction heating or the like), and said film is thermally bonded to the inner surface of the metal tube. The film can be used by overlapping more than two kinds thereof, and it is also possible to apply a bonding agent to the outer surface of the film of the inner surface of the metal tube.
