MMO Tubular Anode String
This anode string is comprised of electrical cable threaded through multiple MMO tubular anodes. The MMO tubular anode is generally titanium tubes coated by an electrocatalytic film of noble metal oxides. The mixed metal oxide coating, with industrially proven lifetime characteristics, ensures an even current distribution along the anodes length.
As a highly conductive anode with extremely low consumption rate, the anode string remains dimensionally constant throughout the design life. They are widely used in deep wells to protect the underground pipe among other steel structures. For improved current output of MMO tubular anodes, coke breeze is commonly used in anode beds, or the anodes are prepackaged in canisters containing carbonaceous backfill ready for installation.

Description
Quality Substrate Material
Our tubular anode is manufactured from high-tensile seamless titanium tube, which meets ASTM B338 Grade 1 standards.
Noble Metal Oxide Coating
The Ir–Ta (IrO2/Ta2O5) mixed metal oxide catalyst sintered to the surface of titanium substrate demonstrates high chemical stability when subject to high current density. We can 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.
Wide Cable Selection
PVDF, HMWPE, HALAR, XLPE, PVC or KYNAR are all optional. We recommend dual-insulated cable(such as PVDF/HMWPE) for use in ground beds with high chloride concentration. While HMWPE is an economical choice for shallow vertical and horizontal surface beds with no chlorides.
Parameters
Testing
We employ rigorous foundry internal testing standards to ensure the optimum lifespan and performance of our Anodes. Each anode is labelled with a unique serial number for quality tracking. Third party testing is conducted by customer’s special request at extra charge.
