Underground structuresVisual inspection of undergorund structures such as tanks or pipelines for the appearance of corrosion is an extremely expensive undertaking. Steel pipes with longitudinal conductivity can be provided with cathodic protection in order to increase corrosion resistance. Monitoring the protection plays a vital role here, as it also allows the pipeline operator to locate defects in the coating and rectify them in good time.
