Cathodic Protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. This is commonly used in pipelines, tanks, and other structures exposed to corrosive environments.
Cathodic Protection works by either using sacrificial anodes or impressed current systems. Sacrificial anodes corrode instead of the protected metal, while impressed current systems apply an external electrical current to reduce corrosion.
Industries such as oil and gas, wastewater treatment, marine, and infrastructure rely on Cathodic Protection to safeguard their assets against corrosion.
A professional assessment is required to determine the need for Cathodic Protection. This typically involves a corrosion survey and analysis of the environment where the assets are located.
