MMO-Coated Titanium Anodes for Impressed Current Cathodic Protection
MMO-coated titanium anodes are dimensionally stable anodes widely used in impressed current cathodic protection systems. Their low and uniform coating consumption, stable current discharge at high operating current densities, and resistance to low-pH and chloride-rich conditions support reliable long-term operation in soil, fresh water, brackish water, and seawater.
Base Material
Commercially pure titanium TA1 / TA2 (equivalent to Grade 1 / Grade 2).
Coating Selection
| Coating Grade | Coating Composition | Typical Application Media | Electrochemical Characteristic |
| FGMMO-1 | IrO2 / RuO2 / TiO2 | Seawater | Predominantly chlorine-evolving conditions |
| FGMMO-2 | IrO2 / Ta2O5 | Soil, fresh water, brackish water and seawater | Mainly oxygen-evolving and mixed O2/Cl2 conditions |
Product Configurations
| Product Type | Structure and Key Features | Recommended Applications |
| Solid Rod Anode | Compact MMO-coated titanium rod with good mechanical strength and flexible installation. | Buried pipelines, water systems and localized protection. |
| Expanded Mesh Anode | MMO-coated expanded titanium mesh with a large active surface area and uniform current distribution. | Tank bottoms, underground facilities and distributed protection systems. |
| General Tubular Anode | Rigid MMO-coated titanium tube designed for radial current discharge. | Pipelines, storage tanks, shallow groundbeds and immersion applications. |
| Seawater Tubular Anode | Tubular titanium anode with an MMO coating selected for chloride-rich environments. | Offshore platforms, wharves, pilings, ship hulls and seawater pipelines. |
| Deep-Well Groundbed Anode | Tubular MMO anode configured for vertical installation in conductive backfill. | Pipelines and underground facilities in high-resistivity soil conditions. |
Application Scenarios
MMO anode selection shall take into account the protected asset, electrolyte environment, installation method and required service life.
01 Buried Pipelines
MMO titanium anodes deliver protective current for buried oil, gas, water and industrial pipelines under various soil conditions.
02 Storage Tanks
Rod, tubular, mesh and ribbon anodes can be configured for tank bottoms and internal wetted surfaces.
03 Marine and Offshore Structures
Application‑specific MMO coatings are available for offshore platforms, wharves, pilings, ship hulls and seawater pipelines.
04 Water Facilities
MMO anodes can be applied to water tanks, wells and submerged steel structures in fresh‑water, brackish‑water or seawater environments.
