METHOD FOR MANUFACTURING LAMINATED PIPE FOR LINING METAL PIPE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminated pipe for lining a metal pipe capable of certainly bringing a resin pipe and an adhesive to a close contact state to laminate them even if resin pipe and the adhesive are not pressed by a roll and capable of enhancing workability or productivity. SOLUTION: In the method for manufacturing the laminated pipe for lining the metal pipe by laminating the adhesive 13, which is extruded from an annular die 12 in a molten state to the outer peripheral surface of the synthetic resin pipe 11, the adhesive 13 is laminated in such a state that static electricity is applied to the synthetic resin pipe 11.
