The MMO Ribbon Anode is a highly efficient and durable anode used in large tank floor protection. It consists of a titanium substrate, which provides structural support and electrical conductivity, and mixed metal oxide (MMO) catalyst coating. 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.
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.

Application
With capabilities for burial and submersion, MMO ribbon anode offers flexible form factors to provide reliable corrosion protection in places and geometries where conventional MMO plates or rods are impractical.
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 environment. This sustains the integrity of critical underground infrastructure like pipelines carrying wastewater, acids, or brine.
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.
