Abstract
A method and system for assessment of a pipe (110) is provided. The system can include a probe (100) having first (120) and second (130) electrodes and a processor (200) in communication with the probe (100). The probe (100) can be in a medium (140) proximate to a section of the pipe (110) to be analyzed. The section of the pipe (110) can have a coating (115) thereon. The processor (200) can measure a difference in potential between the first (120) and second (130) electrodes. The processor (200) can determine a local impedance with respect to the section of the pipe (110) based at least in part on the difference in potential. The processor (200) can evaluate a condition of the coating (115) on the section of the pipe (110) based at least in part on the local impedance or a parameter derived from the local impedance.
