Corrosion Monitoring in the Oil Pipeline Industry

The paper presents current knowledge on corrosion and its monitoring of internal and external corrosion phenomena in the transmission and distribution pipelines in the petroleum industry. The conjoint use of in-line inspection techniques (ILI) and sidestream monitoring techniques are highly favored in order to eliminate catastrophic failures as a result of internal pipeline corrosion problems. External corrosion phenomena in pipelines can be adequately monitored through the deployment of electrode potential measurements using suitable reference electrodes. Improvements in pipeline coatings applications have been highlighted and the often neglected chromating procedure prior to coating application has been addressed with Nigerian patent, NG/P/2013/755 of April, 2014
