BaiQi’s MMO Tubular Anodes feature high-stability Ir-Ta/Ir-Ru coatings, adapting to soil, seawater, even low-pH environments. With 25-year service life, 85%+ coating uniformity, and multiple sizes, they deliver reliable cathodic protection for industrial projects globally.
Industry Pain Point: Corrosion Threatens Critical Infrastructure Lifespan
Metal structures—from underground pipelines, oil/gas storage tanks to marine docks and bridge piers—face relentless corrosion risks from harsh environments: acidic soil (pH≤4), high-salinity seawater (Cl⁻ concentration 3%), and extreme temperatures (-40℃ to 80℃). Traditional anodes (e.g., graphite, high-silicon cast iron) often fall short: high energy consumption, frequent replacement (service life <10 years), and poor adaptability to complex conditions.
Against this backdrop, BaiQi Metal’s MMO (Mixed Metal Oxide) Tubular Anodes emerge as a game-changer, leveraging advanced material technology to deliver long-lasting, efficient corrosion protection for global industrial projects.
Core Advantages: Why BaiQi MMO Tubular Anodes Stand Out
Built with high-purity titanium (TA1/TA2) as the substrate and sintered precious metal oxide coatings (Ir-Ta or Ir-Ru), our MMO tubular anodes redefine performance standards for cathodic protection (CP) systems:
1. Ultra-Long Service Life & Low Maintenance
- Independent laboratory accelerated life tests confirm a 25-year design life—2.5x longer than high-silicon cast iron anodes.
- MMO coating has an annual consumption rate ≤1mg/A, eliminating frequent replacement costs. In seawater, its corrosion rate is <0.1mm/a (vs. 0.5mm/a for high-silicon cast iron).
2. High Efficiency & Energy Savings
- The honeycomb porous coating (porosity 35-45%) expands the effective reaction area by 5-8x, enabling stable operation at 100-600A/m² current density.
- Electric energy conversion efficiency reaches 95-98%, reducing energy consumption by over 60% compared to traditional graphite anodes.
3. All-Environment Adaptability
- Multi-scene compatibility: Ideal for soil, freshwater, seawater, mud, and even low-pH acidic environments (pH4) or high-resistivity desert soil.
- Wide temperature range: Stable performance from -40℃ (permafrost regions) to 80℃ (high-temperature soil), solving the "dead zone" problem of traditional anodes.
Tailored Specifications for Diverse Projects
To meet the unique needs of different industries, BaiQi offers a full range of standardized and customized MMO tubular anode sizes, with key parameters optimized for specific scenarios:

Two coating formulations further enhance adaptability:
- Ir-Ta Coating (IrO₂-Ta₂O₅): Perfect for fine sand, coke breeze, and freshwater environments.
- Ir-Ru Coating (IrO₂-RuO₂): Optimized for mud, concrete, and seawater (e.g., marine docks, offshore platforms).
Quality Assurance: ISO-Certified & Globally Trusted
As a leading provider of electrochemical solutions, BaiQi adheres to ISO 9001 quality standards throughout production. Every MMO tubular anode undergoes strict testing:
- Coating uniformity inspection (minimum 85% uniformity).
- Electrochemical performance verification (open-circuit voltage, current efficiency).
- Environmental resistance trials (acid/alkali immersion, temperature cycling).
Our anodes have been successfully applied in projects across Southeast Asia, Europe, and the Middle East—protecting oil pipelines in Indonesia, marine piers in the UAE, and water treatment facilities in the Czech Republic.
