Safe pipeline transportation and storage of liquid petroleum products necessitate the use of several methods of corrosion control, including protective coatings, cathodic protection and corrosion monitoring. When a polarization potential survey was performed on a recently acquired 35-mile long pipeline, the survey indicated areas of marginal protection. The results of the survey necessitated a more comprehensive investigation to establish remedial measures, including supplemental protection. Accordingly, the effectiveness of installing a high voltage, pulse rectifier, at the pumping station end of the buried steel pipeline, to improve protection distribution at the remote reaches, was confirmed.
