What is Mmo Ribbon Anode
The MMO Ribbon Anode is a highly efficient and durable anode used in various cathodic protection applications. It consists of a titanium substrate coated with a mixed metal oxide (MMO) catalyst. This anode is specifically designed to protect metallic structures from corrosion by supplying a protective current.
The MMO Ribbon Anode is constructed using high-quality titanium with an MMO catalyst coating. The anode utilizes the principle of electrochemical reactions to provide cathodic protection to structures submerged in electrolytes. The MMO catalyst ensures a highly active and stable anode performance, making it ideal for long-term corrosion prevention.
Working Principle
The Mixed metal oxide Anode operates based on the electrochemical reaction of the MMO catalyst when connected to a DC power source. The MMO catalyst facilitates the production of oxygen ions, which combine with water molecules to form hydroxyl ions. The hydroxyl ions provide an excess of electrons to the structure, effectively preventing corrosion.
System Components and Structure
It has the following components:
● Titanium substrate - Provides structural support and electrical conductivity.
● MMO catalyst coating - Facilitates electrochemical reactions and enhances anode performance.
The anode has a ribbon-like structure, allowing for easy installation on various surfaces. Its flexible nature ensures complete contact with the protected structure, maximizing the efficiency of the cathodic protection system.

Applications
Mixed metal oxide (MMO) ribbon anodes have become an important cathodic protection technology for corrosion prevention in major industries like oil and gas, marine transport, and municipal water infrastructure.
● Underground pipelines and tanks
A key application is providing corrosion protection for buried metallic pipelines and tanks transporting or containing corrosive substances. Mixed metal oxide ribbon anodes buried alongside or connected to the assets provide protective current flows that counteract external corrosion elements in the soil/water environment. This sustains the integrity of critical underground infrastructure like pipelines carrying wastewater, acids, or brine.
● Marine structures
In marine settings, attached to the submerged surfaces of ships, tankers, offshore rigs, and port structures generate protective currents that mitigate corrosion from seawater. The MMO materials resist seawater reactions while providing optimal current output to protect propellers, rudders, mooring devices, and other underwater assets vulnerable to electrolytic corrosion. This prevents damage, leaks, and failures.
● Oil and gas infrastructure
For above-ground storage tanks holding crude oil, acids, or other corrosive products, it is attached to tank exteriors to neutralize corrosion by supplying protective current flows. This maintains tank integrity and prevents leaks, explosions, and environmental contamination.
● Water treatment facilities
At water and wastewater treatment plants, it is utilized to protect submerged assets like clarifiers, screens, and sludge collection pipes made of metallic materials like carbon steel. Providing cathodic protection preserves equipment reliability and prevents corrosion contaminants from leaching into water supplies.
With capabilities for burial and submersion, it offers flexible form factors to provide reliable corrosion protection in places and geometries where conventional MMO plates or rods are impractical. As infrastructure ages globally, it will continue to see increased adoption for safeguarding critical assets against corrosion damage and failures.
