MMO Canister Anode

 Canister anodes consist of MMO/Ti (tubular, wire, rod, mesh) anode installed in a large metal canister that is filled with coke breeze backfill. They are commonly used for impressed current anode cathodic protection applications.

 

UTron provide canister anodes with core in MMO tubular or wire anode wrapped with galvanized steel canister. The canister is capped with the anode cable extending out the top of the anode cap. It is commonly used in cathodic protection field, such as buried pipelines or ground beds.

Construction:

The basic anode in an canister anode is a MMO wire or tubular anode, which is comprised of a precious metal oxide coating applied to a titanium base. The metal oxide coating is completely stable, and does not corrode, as is the case with traditional massive type anodes, such as silicon iron, graphite.

 

The stable anode element passes current to a highly conductive calcined petroleum coke breeze. This backfill is well compacted inside a galvanized steel canister. To allow moisture to quickly migrate to the coke breeze for increased electrical conductivity, the MMO anode element is electrically connected to the steel canister - thereby accelerating the canister corrosion rate once the anode has been installed and energized.
