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.
Maintenance & Storage Guidelines
Handling: Avoid sharp bends, kinks, abrasion, or any mechanical damage that could compromise the titanium substrate or the MMO coating.
Inspection: Prior to installation, visually inspect the anode wire for any signs of damage to the coating or integrity.
Cleaning: If heavily soiled, clean with fresh water and a soft cloth. Avoid abrasive cleaners or solvents that could damage the coating.
Storage: Store in a dry, well-ventilated indoor environment away from direct sunlight, extreme temperatures, and corrosive fumes. Keep the wire on its original coil or spool to avoid tangling and stress.
Post-Installation Monitoring: While the anode itself requires no routine maintenance, the overall cathodic protection system should be monitored periodically (e.g., every 3-6 months) for output current and protection potential (typically between -0.85V to -1.1V vs. a reference electrode) to ensure the system is functioning correctly.

FAQ
01.Can you customize the diameter and length of the anode wire?
Yes, absolutely. We offer a range of standard diameters like 1.5mm and 3.0mm, but we can produce other specified sizes and cut lengths to your exact requirements.
02.How does the MMO coating improve upon traditional anode materials?
The Mixed Metal Oxide (MMO) coating provides superior electrocatalytic activity, very low consumption rates, high stability in harsh environments, and excellent current distribution compared to traditional materials like graphite or iron, leading to longer life and better efficiency.
03.Is this anode wire suitable for use in seawater?
Yes. Our MMO titanium anode wire is highly resistant to chloride attack and is well-suited for applications in seawater, marine environments, and offshore structures.
04.What is the difference between your standard and custom-coated anodes?
We offer different coating formulations (e.g., IrO₂-Ta₂O₅, RuO₂-IrO₂) optimized for specific electrochemical reactions (e.g., chlorine or oxygen evolution) and environments. We can help you select or customize the coating for optimal performance in your application.
05.Do you provide technical support for system design?
While we provide the high-quality anodes, the design of the complete cathodic protection system should be undertaken by a qualified corrosion engineer. We can supply product data and specifications to assist in their design process.
