Cathodic Protection Anode

Cathodic protection is a crucial technique employed to prevent corrosion in various metal structures, ensuring their longevity and structural integrity. MMO (Mixed Metal Oxide) anodes play a pivotal role in this corrosion prevention strategy. These anodes are a specialized type of impressed current anode that utilizes a combination of various metal oxides to create an efficient and durable electrochemical reaction.

Unlike traditional sacrificial anodes that are consumed during the corrosion process, MMO anodes operate as non-consumable electrodes. This unique characteristic allows them to provide long-lasting protection to structures submerged in corrosive environments, such as pipelines, storage tanks, and offshore platforms.

The fundamental principle behind MMO anodes lies in the electrochemical potential difference between the anode and the structure to be protected. When connected to a power source, the MMO Anode releases electrons, creating a cathodic protection current that counteracts the natural corrosion process. This current effectively shifts the metal structure from anodic to cathodic potential, mitigating the risk of corrosion and extending the service life of the protected asset.
