mmo coated titanium anodes for cathodic protection

MMO Coated Titanium Anodes for Cathodic Protection Introduction

MMO coated titanium anodes for cathodic protection are advanced electrodes designed for cathodic protection systems. These anodes are essential in preventing corrosion in a variety of industries, from marine to energy and environmental sectors. They provide long-lasting protection to metal structures by emitting current that mitigates the effects of corrosion. Titanium’s inherent corrosion resistance, combined with the efficient MMO (Mixed Metal Oxide) coating, makes these anodes an ideal solution for harsh environments. Whether you're protecting pipelines, ships, or offshore structures, MMO coated titanium anodes ensure reliability and efficiency.

At Baoji City ShenAo Metal Materials Co., Ltd., we specialize in producing high-quality MMO coated titanium anodes that cater to your specific needs. Our products are manufactured using cutting-edge technology, ensuring superior performance and longevity in all cathodic protection applications.

MMO Coated Titanium Anodes for Cathodic Protection Technical Specifications

Manufacturing Process of MMO Coated Titanium Anodes

The production of MMO coated titanium anodes for cathodic protection requires advanced metallurgical and coating technologies to guarantee quality and performance.

1: Titanium Substrate Preparation

High-grade titanium sheets, rods, or wires are carefully selected and prepared. The titanium surface undergoes mechanical polishing and chemical cleaning to remove oxides and impurities.

2: Coating Application

A specially formulated slurry of mixed metal oxides is applied to the titanium substrate. This coating may include iridium oxide (IrO₂), ruthenium oxide (RuO₂), or other noble metal oxides depending on the application requirements.

3: Heat Treatment

The coated titanium is subjected to controlled heat treatment cycles. This process bonds the MMO layer to the titanium substrate, enhancing adhesion, conductivity, and durability.

4: Quality Control

Each batch undergoes rigorous inspection, including thickness measurement, surface bonding tests, and electrochemical performance evaluation to ensure consistent quality.

Advantages of MMO Coated Titanium Anodes for Cathodic Protection
1. Longevity and Reliability

With service lives exceeding 20 years, these anodes offer long-term protection with minimal maintenance.

2. Cost Effectiveness

Though initial investment may be higher than traditional anodes, the extended life and reduced maintenance make MMO coated titanium anodes for cathodic protection more economical in the long run.

3. High Efficiency

Their excellent electrochemical activity ensures efficient cathodic protection, reducing energy consumption.

4. Versatility

They are adaptable to multiple industries and can be customized in various shapes and sizes to meet specific project needs.

5.Safety and Sustainability

Unlike consumable anodes such as magnesium or zinc, MMO titanium anodes produce minimal by-products, making them environmentally sustainable.

Industry Applications of MMO Coated Titanium Anodes for Cathodic Protection
1. Oil and Gas Industry

In oil and gas, corrosion control is essential for pipelines, offshore platforms, and subsea equipment. MMO coated titanium anodes provide reliable cathodic protection for buried pipelines and marine installations, preventing costly failures.

2. Marine Structures

Ship hulls, harbors, jetties, and seawater intake structures are constantly exposed to saline conditions. MMO coated titanium anodes are highly effective in extending their operational life.

3. Storage Tanks

Above-ground and underground storage tanks are susceptible to corrosion at soil interfaces and water bottoms. Using MMO coated titanium anodes for cathodic protection ensures safety and structural integrity.

4. Reinforced Concrete Structures

Bridges, tunnels, and parking garages reinforced with steel rebar often suffer from chloride-induced corrosion. MMO anodes embedded in concrete prevent rebar degradation and prolong infrastructure lifespan.

5. Power Generation

Cooling water systems, condensers, and intake structures in power plants benefit from MMO titanium anodes to reduce corrosion and maintenance costs.

MMO Coated Titanium Anodes for Cathodic Protection Application Case 
1. Offshore Oil Platform Protection

A major offshore oil platform in the Middle East adopted MMO coated titanium anodes for cathodic protection. The anodes demonstrated excellent stability under high salinity conditions, reducing downtime and extending platform service life by decades.

2. Bridge Rehabilitation

A coastal highway bridge experienced severe rebar corrosion due to chloride intrusion. By embedding MMO coated titanium mesh anodes into the concrete, engineers restored the structure and ensured long-term durability with minimal maintenance.

3. Pipeline Cathodic Protection

A natural gas company installed MMO coated titanium tubular anodes along a buried pipeline network. The installation significantly reduced corrosion rates and operational risks, ensuring reliable energy distribution.
