Cathodic protection (CP; / kæˈθɒdɪk / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. [1] A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode.
Cathodic protection is a proven electrochemical method used to prevent corrosion of metal surfaces. It works by redirecting corrosion currents away from the protected structure, ensuring long-term durability and safety.
Cathodic protection is a popular protection method for preventing corrosion in pipelines, offshore oil platforms and other steel structures. However, to be implemented effectively, it is crucial to understand the basic principles of bimetallic/galvanic corrosion.
The Institute of Corrosion offers courses in cathodic protection, providing the training required for levels 1 to 3 for cathodic protection data collectors, technicians and senior technicians.
Cathodic Protection is an industrial technique for controlling metallic corrosion. Cathodic protection is commonly used on buried and submerged metallic structures like pipelines, underground storage tanks, locks, subsea equipment, offshore floaters, harbors, and ship hulls.
