What is Cathodic Protection and Why is it Essential?

Cathodic Protection is an essential method for preventing corrosion in various metal structures, particularly those exposed to harsh environments, such as pipelines, tanks, and marine vessels. At its core, Cathodic Protection works by using electrochemical principles to counteract the natural process of corrosion. By applying a small electrical current or utilizing sacrificial anodes, it effectively redirects the electrochemical reactions that lead to metal degradation.

The importance of Cathodic Protection cannot be overstated when it comes to corrosion control. Corrosion not only leads to structural failures but also poses significant safety risks and financial burdens due to repairs and replacements. Internal corrosion is especially concerning in pipelines carrying fluids; if left unchecked, it can result in leaks or catastrophic failures that compromise both safety and operational efficiency.
