Abstract
PURPOSE: To obtain the metallic pipe lined with a resin pipe adhered uniformly and rigidly onto the inside surface thereof by a method wherein a heat-sensitive adhesive is coated by extrusion on the outside peripheral surface of an extruded synthetic resin pipe capable of being expanded in diameter by heating, before the resin pipe is solidified by cooling, ad the resin pipe is inserted into the metallic pipe and is heated.
CONSTITUTION: After extruding the synthetic resin pipe 2 from an extruder 1 but before the resin pipe 2 is solidified by coolding, the heat-sensitive adhesive melt- extruded from an extruder 3 is coated on the outside peripheral surface of the pipe 2 in the form of an annular thin layer by a crosshead die 4, then a tension is applied to the pipe 2 while reducing its diameter by a forming device 6 and the pipe 2 is solidified by cooling by a cooler 7, thereby obtaining the adhesive-coated synthetic resin pipe 9 provided with the property of being expanded in diameter by heating. The resin pipe 9 is inserted into the metallic pipe and is heated, whereby the metallic pipe lined with the resin pipe 9 adhered closely and rigidly to the inside surface thereof can be obtained.
