INSULATING COATING EMBEDDED PIPE AND ITS COATING INSPECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an insulating coating embedded pipe for alloying easy feeding at other portions than a portion rising on a ground of the pipe embedded into the ground. SOLUTION: The insulating coating embedded pipe comprises at least one feeding body 13 connected to the outer peripheral face of a metal pipe 12 and protruded from the outer peripheral face, and an insulating coating 14 for covering the outer peripheral face of the metal pipe 12 and the outer peripheral face of the feeding body 13. A damaged position detecting signal is applied to the upper end of the feeding body 13 exposed to the ground to detect a damaged position with a change of potential or a magnetic field.
