ABSTRACT:
This method and apparatus detects the potential for corrosion of pipes fabricated out of conductive material embedded in non-conductive material, due to contact between a conductive medium foreign to the pipe and the conductive material embedded within the pipe wall. The electric potential between the foreign medium and the pipe conductive material is determined. The stability of the potential is then ascertained. If the potential does not vary beyond a predetermined range over a period of time, the potential is deemed stable and is indicative of contact between the foreign medium and the conductive material within the pipe, fostering corrosion. An unstable voltage indicates lack of electrical contact.
