  • Principles of Cathodic Protection

    Credits: 4 PDH

    PDH Course Description:

    Electrochemical corrosion is a process by which an electrical current leaves a metal structure (like a buried pipeline or underground tank) at an anode site, passes through an electrolyte (soil or water), and re-enters the structure at the anode site, causing pit corrosion at the anode site. This course describes procedures for designing a cathodic protection system, using a sacrificial anode or an anode with impressed electrical current to prevent electrochemical corrosion.

    Topics:

    • introduction to cathodic protection
    • cathodic protection design
    • soil resistivity measurement
    • current requirement testing
    • example of "galvanized" and "impressed current" cathodic protection design
    • specifications for ceramic anodes
    • rectifier current interference
