This is an introduction to cathodic protection for underground structures such as tanks and pipelines. It covers the two principal methods used to mitigate corrosion: the sacrificial anode and impressed current systems. It introduces you to the nine steps in designing a sacrificial anode system, the thirteen steps in designing an impressed current system, and the field testing requirements needed for both. It is intended for engineers and other construction professionals with a current or prospective need to understand the fundamentals of protecting underground structures such as tanks and pipelines from corrosion using sacrificial anode and impressed current cathodic protection systems.
