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.

UTron provide MMO cylindrical deep well anode（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.
This Type of Titanium Disk Anode surface of mixed metal oxide (MMO) or platinum applied on pure titanium (Ti) base. Used for impressed current cathodic protection of ship hulls or offshore platforms or Electrodialysis equipment, etc.
MMO linear anodes are a flexible, prepackaged porous, woven acid-resistant sleeve linear anode contains high conductivity calcined petroleum coke breeze. This sleeve is sewn using a poly two or four-thread double interlocking stitch, which prevents the seam from separating during installation, or when stored in high temperature conditions. This arrangement avoids handling loose coke breeze and simplifies field installation. It improved current distribution increases anode efficiency and helps prevent over-voltage problems such as hydrogen generation and associated rapid coating disbondment. In addition, interference from other structures and stray currents are virtually eliminated.
Anodes in a water heater are divided into sacrificial anode rods and titanium anode rods. A sacrificial anode rod is an exposed metal rod that is inserted into the water heater. It is designed to corrode slowly over time. The sacrificial anode is made from either magnesium, aluminum, or zinc. The lifespan of sacrificial anodes varies greatly based on local water conditions and quality. Annual inspection and replacement for sacrificial anode rods are recommended. In areas with sulfides in the water, there is a reaction with magnesium anodes which creates hydrogen sulfide gas that creates a rotten egg smell in the water. In areas with high conductivity water, aluminum anodes are depleted too quickly, leaving the tank unprotected.
The MMO Ribbon Anode consists of mixed precious metal oxides that are sintered to the surface of titanium substrate to have electro catalytic characteristics. This mixed metal oxide anodes have an extremely low consumption rate, the titanium substrate remains constant throughout the design life of the anode. It can be used in fresh water, brackish water, seawater, coke, or sand environment in cathodic protection application with long operating life.
MMO Tubular titanium Anode provides longest life and greatest current output in all ICCP anodes for the sake of its largest surface area and the compact cable connection. It has been proven to operate effectively in all types of environments, including areas with extremely low pH levels (under 1), and high chloride concentrations. It can be used in strings on offshore platforms or in deep ground beds and other application. UTron has dedicated to MMO tubular anode manufacturing for decades. The MMO tubular anode for cathodic protection of UTron meets ASTM B338 standards in Grade 1 or Grade 2, coated with Iridium - Tantalum - Titanium (IrO2/Ta2O5) coating, widely used in cathodic protection fields. The anodes have been proven to have an extremely low consumption rate and the titanium substrate remains constant throughout the design life of the anode. UTron has strict quality control procedures throughout the whole production process. Each batch is subjected to thorough testing. The anode performance is confirmed by the acceleration acid testing using NACE Standard TM0108. It enables the most cost-effective anode in the industry.
