Products Description
MMO Titanium Anode Wire is a high-performance flexible anode material used in impressed current cathodic protection (ICCP) systems.
The anode consists of a titanium wire substrate coated with mixed metal oxides (MMO) such as iridium and tantalum.
Compared with traditional sacrificial anodes, MMO titanium anode wire offers:
● extremely long service life
● stable electrochemical performance
● low consumption rate
● uniform current distribution
This type of flexible titanium wire anode is widely used for pipeline protection, storage tank protection, water heater cathodic protection, and underground structure corrosion control.
Ehisen provides customizable MMO coated titanium anode wire with stable coating quality and reliable service life for industrial corrosion protection systems.

customization options
We understand that projects have unique requirements. Ehisen offers extensive customization for your MMO titanium anode wire:
Dimensions
Diameter (e.g., 1.5mm, 3.0mm, or other specified sizes), length (cut to your specific needs), and packaging (coils or spools).
Coating Formulation
We can tailor the mixed metal oxide coating composition (e.g., IrO₂-Ta₂O₅ for chlorine environments, RuO₂-IrO₂ for oxygen evolution) to optimize performance for your specific electrolyte and application.
Electrical Configurations
Custom connections, cabling, and packaging to suit your cathodic protection system design, including options for continuous horizontal ground beds or canistered anodes.
Connection Reliability
Cable sealing, termination, and electrical continuity are important for long-area installations.
Coating Characteristics
The heart of our anode’s performance lies in its advanced MMO coating.
High Catalytic Activity: Facilitates efficient electrochemical reactions, enhancing the overall efficiency of your cathodic protection process.
Low Consumption Rate: The coating’s wear rate is remarkably low, measured in milligrams per ampere-year (e.g., ≤5mg/(A·year)), contributing to the long service life.
Excellent Coating Adhesion: The coating is firmly bonded to the titanium substrate through a meticulous process, with adhesion strength exceeding 15 MPa, preventing premature peeling or failure.
Corrosion Resistance: Highly resistant to attack in a wide range of aggressive environments, including acids, chlorides, and other harsh electrolytes.
Low Overpotential: Reduces energy consumption during electrolysis, leading to significant cost savings over the system’s lifetime.

Applications & Role in Cathodic Protection
Ehisen’s MMO Titanium Anode Wire is indispensable in Impressed Current Cathodic Protection (ICCP) systems across numerous industries. ICCP works by connecting an external DC power source to the anode (our wire) and the structure to be protected (the cathode). Current flows from the anode, through the electrolyte (soil/water), to the cathode, effectively suppressing the corrosion reaction on the cathode surface.
1.Pipeline Protection: Used in continuous horizontal ground beds or canistered anodes to protect long-distance buried pipelines for oil, gas, and water, especially in complex layouts and high-resistivity soils.
2.Tank Farm & Storage Tank Protection: Installed beneath or around above-ground and underground storage tank bottoms (e.g., for oil, chemicals, water) to prevent corrosion, often in concentric patterns for uniform current distribution.
3.Marine & Offshore Structures: Protects ship hulls, offshore platforms, docks, piers, and submarine pipelines from aggressive seawater corrosion.
4.Water Treatment & Storage: Used in water treatment equipment, water storage vessels, and electrolysis processes within treatment plants due to its resistance to varying water chemistries.
5.Cable Protection: Shields critical communication and power cables buried in the ground.
6.Reinforced Concrete Structures: Helps prevent corrosion of rebar in bridges, parking garages, and other concrete structures exposed to de-icing salts or marine environments.
