<p>The object is to provide a pipe connecting structure which can prevent electrical charge of a plastic coated metal pipe using a simple structure. In order to accomplish this object, beads 5a, 5b, 5c are provided to protrude from the outer surface of the end of a plastic coated metal tube 3 obtained by coating the outside of a bare metal pipe 1 with a nonconductive plastic film 2, the plastic film 2 is removed from the tip of the bead 5a to expose the circumferential surface of the bare metal pipe 1, the exposed portion is made to contact the inner surface of a conductive tube 4, thus connecting the plastic coated metal tube 3 and the conductive tube 4.</p> |
