Cathodic Protection (CP) is an electrochemical method of corrosion prevention, which can be applied to metallic infrastructure exposed to conductive environments (i.e. buried pipelines or storage tanks). The technique utilizes the circulation of a continuous current between an electrode (anode) placed in the environment (i.e. soil) and the metallic structure to be protected (cathode). This cathodic current lowers the electrochemical potential of the metal and therefore reduces its corrosion rate.
