When Is Cathodic Protection?

Cathodic protection is often used to mitigate corrosion damage to active metal surfaces. It is used all over the globe to protect pipelines, water treatment plants, above and underwater storage tanks, ship and boat hulls, offshore production platforms, reinforcement bars in concrete structures and piers, and more.

Where is cathodic protection required?

What is cathodic protection and how does it work?

Cathodic protection works by placing an anode or anodes (external devices) in an electrolyte to create a circuit. Current flows from the anode through the electrolyte to the surface of the structure. Corrosion moves to the anode to stop further corrosion of the structure.
