METHOD FOR MANUFACTURING HEATABLE PIPE

摘要

PROBLEM TO BE SOLVED: To provide a conduit capable of applying excellent and continuous connection between an electrode and a conductive polymer base material by small contact resistance and capable of easily finding a position of the electrode so as to achieve contact connection with the electrode at a desired position through a connection member and to achieve electric conduction.SOLUTION: A method for manufacturing a heatable conduit includes a step a) for performing extrusion molding of a two-layer pipe including an electrically insulating inside layer 1 and a first conductive layer 2, a step b) for winding at least two conductors 5, 6 spirally around the first conductive layer 2, a step d) for applying a second layer 3 comprised of a conductive molding compound by extrusion molding so that the thickness of the second layer 3 becomes 0.1-1.5 mm, and a step e) for applying an outside coat layer 4 comprised of an electrically insulating plastic material.
