Titanium anode for Cathode protection

Titanium anodes are critical components in impressed current cathodic protection (ICCP) systems, designed to prevent corrosion of metallic structures in harsh environments such as soil, seawater, and industrial systems.

Baoji City Changsheng has developed a range of titanium anodes with advanced coating systems, including ruthenium-based (Ru) and iridium-based (Ir) mixed metal oxide (MMO) coatings. These coatings provide excellent electrochemical stability, low consumption rates, and long service life.

Key Applications

These anodes have been widely used in major infrastructure and energy projects, including:

Oil & gas pipelines

Underground and aboveground storage tanks

Offshore platforms

Bridge structures

National petroleum reserve systems

Technical Advantages

Excellent corrosion resistance in seawater, freshwater, and soil

Low coating consumption rate (~0.1 mg/A·year)

Stable performance even at high current densities

No passivation or rapid dissolution under normal operating conditions

Adaptable coating systems for different environments

Performance Parameters

Coating resistivity: ~10⁻⁷ Ω·m

Typical operating current density:

Soil: ~100 A/m²

Seawater: up to 600 A/m²

Service life:

≥20 years in soil environments

≥20 years in marine environments

Design Flexibility

By adjusting the composition of the MMO coating, titanium anodes can be optimized for:

High-chloride environments (seawater)

Low-resistivity soils

Industrial process conditions

Bottom line

Titanium MMO anodes provide a long-life, low-maintenance, and cost-effective solution for corrosion protection, making them the preferred choice for large-scale industrial and infrastructure projects.
