MMO Vertical Tension Anode String

This vertical tension anode string is an anode array that comprises a series of MMO tubular anodes chained onto an electrical cable. The terminal anode (the last anode on a string assembly) has a metal loop fixture to be used for attaching weights.

The MMO tubular anode secured into the perforated PVC casing pipe, is made from titanium tubes coated with a mixed metal oxide catalyst. Our MMO coating consists of Iridium-Ruthenium oxides (IrO2/RuO2) and it has been proven to have an excellent performance within the design life.

Our high performance MMO vertical tension anode is extremely durable and can be used in severe environment conditions, including high acidity and in the presence of chlorine or oxygen. It is a cost-effective option used in the impressed current cathodic protection systems of offshore or marine structures. It can be installed without divers or ROV equipment.

Quality Substrate Material
Our MMO tubular anode is manufactured from high-tensile seamless titanium tube, which meets ASTM B338 Grade 1 standards.

Noble Metal Oxide Coating
The Iridium-Ruthenium (IrO2/RuO2) mixed metal oxide catalyst sintered to the surface of titanium substrate demonstrates high chemical stability, even in environments with low pH values. We are able to produce anodes with differing coating thickness and noble metal oxide ratios upon request. Strict quality control procedures are followed throughout the coating process to ensure appropriate coating thickness and adhesion. Based upon accelerated life testing, conducted by an independent laboratory, our MMO coating has been proven to have an increased life expectancy when compared with other similar products on the market.

Low Electrical Resistance
The anode has an extremely low consumption rate, measured in milligrams per ampere-year. The dimensions remain nearly unchanged throughout the design life of the anode, providing a consistently low resistance.

Strict Quality Control
By conforming to ISO 9001:2015 standards, our anode strings are manufactured, inspected, and tested in accordance with our stringent quality control procedures to ensure peak performance.

Customized Configurations
We have developed a complete production line for MMO anode in ICCP fields. With the help of our experienced engineers, we can customize the anode size, service life and output current to meet your specific needs upon request.
