Products Description
The Customized Ru-Ir Coated MMO Titanium Anode is a purpose-engineered, dimensionally stable anode (DSA) tailored specifically for your Impressed Current Cathodic Protection (ICCP) and structural corrosion mitigation challenges.
Unlike conventional fixed-spec electrodes, our MMO anodes are fully adaptable to your project's unique electrical requirements. For special control systems, optional electrical matching such as a 100 Ω assembly resistance can be provided according to customer requirements.
Manufactured on a substrate of industrial pure titanium (Gr1 or Gr2), and featuring a uniform mixed metal layer with a thickness tailored to your cost and mechanical needs (typically tunable within 0.5–5μm, or as required). This proprietary formulation guarantees high current efficiency and exceptional chemical stability across marine soil, seawater, brackish water, and concrete structures.
Furthermore, all mechanical interfaces-including CNC-machined slots, threading configurations, and end connections-are designed and manufactured strictly per your drawings. This ensures seamless installation, minimal contact resistance, and reliable long-term anti-corrosion protection for your critical global infrastructure assets.

Products applications
Impressed Current Cathodic Protection (ICCP)
– Cathodic protection for buried long-distance oil & gas steel pipelines.
– Corrosion mitigation for underground storage tank bottoms (AST/UST).
– Long-term corrosion tracking and potential monitoring elements within concrete structures.
Marine Infrastructure Anti-Corrosion
– Corrosion protection for steel sheet piles, docks, harbor structures, and coastal concrete pillars.
– Current emission for ship hulls, offshore oil/gas drilling platforms, and marine cooling water inlets.
Automated Electrochemical Control Systems
– Functioning as a high-precision, 100-ohm calibrated resistance-matched element in automated close-interval potential surveys and closed-loop CP systems.
Product Advantages
Compared to conventional bulk metal anodes and standard uncalibrated titanium electrodes, our customized ruthenium-iridium coated MMO anode offers distinct competitive advantages:
Powerful Customization and Engineering Execution
We specialize in translating vague operational requirements or worn physical components into fully documented engineering realities. Our CNC facility accommodates custom dimensional lengths, specialized threads, and precise coating formulations to fit legacy equipment perfectly.
Tremendous Patience and Technical Rigor
Rather than taking shortcuts or providing rushed approximations, our engineering team commits to thorough testing cycles. We routinely address complex manufacturing anomalies-such as maintaining tight tolerances across multi-layer high-temperature sintering lines-to ensure a flawless physical replication.
High Product Quality and Operational Stability
Our proprietary multi-layer thermal decomposition formulation secures an elite microstructural bond between the Ru-Ir layer and the titanium base. The anode exhibits zero coating degradation or peeling under fluctuating current densities, ensuring excellent dimensional stability.
Logistics and Environmental Resilience
Engineered to withstand long-distance shipping stress and high thermal expansion/contraction variables, our modified assembly tolerances ensure structural integrity, preventing loosening or mechanical failure during field installation.
Precision Electrical Impedance Matching
By locking the total circuit resistance to exactly 100 ohms, we eliminate the risk of voltage spikes or control grid errors. This precision calibration provides global procurement teams with a true "drop-in" replacement that requires zero field system recalibration.

FAQ
What parameters or data do I need to provide for a custom cathodic protection anode replication if I do not possess technical blueprints?
We offer multiple flexible integration paths depending on your available data:1. Physical Sample: Send us a physical sample (even a degraded or field-worn component). Our technical center will perform structural mapping, chemical profiling, and destructive analysis to recreate precise engineering blueprints. 2. Known Specifications: Provide available technical parameters, such as primary dimensions, thread types, and environmental variables (e.g., soil resistivity or water chemistry). 3. Application Demand: If no blueprints or samples exist, simply share your specific cathodic protection target and operational environment, and our engineering team will design a customized anode configuration from scratch.
How can I get some samples for test?
Free samples are available (you bear shipping cost). Bulk production will follow the confirmed sample standards.
Can your facilities machine specialized end-connection threads or replicate accompanying insulating sleeves based on our sample?
Yes. Our internal CNC machining department can precision-cut custom threads (such as the M5 slot and thread featured here) and source or fabricate matching non-metallic components, insulating caps, or mounting accessories to match your field requirements exactly.
Is this customized MMO titanium anode fully RoHS compliant?
Yes. Both our industrial-grade pure titanium base material and our proprietary ruthenium-iridium mixed metal oxide coating contain no restricted hazardous substances, fully complying with European RoHS regulations.
