Abstract

PURPOSE:To obtain the synthetic resin lining of excellent adhesion stregnth for a tube, by inserting into the metal tube the radially heat-expandable synthetic resin tube which is covered by the heat-sensitive adhesive extruded cylindrically, being exerted with pressurizing force to the clearance between them. CONSTITUTION:The pressurizing chamber 5 having the throughhole 51 for the resin tube 1 is provided around the circular delivery port 24 and the heat-sensitive adhesive layer 3 extruded cylindrically from the circular delivery port 24 is covered on the radially heat-expandable synthetic resin tube 1 from the outside, being exerted with fluid pressure by supplying pressurizing gas into the pressurizing chamber 5 by the pressurizing blower 4 etc. Then, by the inserting the adhesive-covered resin tube into the metal tube and heating, it is radially expanded and firmly adhered to the inner surface of the metal tube without volatilizing noxious organic solvent etc.
