Abstract: This paper describes the principles and applications of a system for monitoring active corrosion on buried gas pipelines using sensitive, dc coupled magnetometers to detect currents flowing on and from a buried pipeline. The frequency dependence of these currents can be analyzed to determine the rate of local corrosion if the corroding area is known. When the corroding area is not known, the relative corrosion rates of segments-of the pipeline approximately three feet long can be determined. Note that this system measures instantaneous corrosion rate, not metal loss associated with past corrosion. In this sense the method described in this paper is intended to identify active corrosion and allow mitigation before damage to the pipeline has occurred. If the relative corrosion rate is measured over time, then the extent of accumulated damage could be determined.
