The MMO Tubular Titanium Anode is a highly efficient and reliable anode used in various industries for cathodic protection applications. It is designed to provide long-lasting corrosion resistance while offering exceptional performance. It is made of a titanium substrate coated with a mixed metal oxide (MMO) catalyst. This catalyst ensures a stable and consistent current distribution during operation, reducing corrosion and extending the anode’s lifespan. The anode operates on the principle of impressed current cathodic protection, where the MMO catalyst promotes the electrochemical reaction between the anode and the surrounding environment. This reaction creates an electric current that protects the target structure from corrosion.
The MMO Tubular Titanium Anode consists of a titanium tube with a coated MMO catalyst. The anode is typically installed within a concrete or soil environment, allowing it to protect structures such as pipelines, storage tanks, and reinforced concrete. The key features and advantages of MMO tubular titanium anode are as follows:
- Long lifespan for more than 20 years
- Excellent coating thickness ranging from 8 to15 μm and customized according to different requirements
- Uniform current distribution, 100A/m2 in soil/freshwater environment and 600A/m2 in seawater environment
- High corrosion resistance in seawater, soil and freshwater environment
- Wide range of tubular diameters, customized according to customer requirements

Application
Mixed metal oxide (MMO) coated tubular titanium anodes have emerged as an important technology for corrosion prevention across industrial infrastructure sectors like wharf steel piles, deep-sea platforms, small tank farms and deep well.
Wharf steel piles
For reinforced concrete structures like pilings, piers, and wharfs in marine environments, MMO titanium anodes embedded within the concrete matrix during construction generate protective currents to reinforce steel rebar against chloride-induced corrosion stemming from seawater exposure. This prevents costly structural degradation.
Deep-sea platforms
MMO tubular titanium anodes deliver excellent performance for protecting submerged assets on offshore platforms, and port structures from seawater corrosion. Their tubular profile can be integrated into complex marine structures.
Small tank farms
MMO tubular titanium anodes act as auxiliary anodes for above-ground storage tanks containing acids, solvents or other corrosive chemicals. This provides a protective current to shielded tank areas vulnerable to corrosion, maintaining tank integrity and preventing leaks or failures.
Deep well
MMO tubular anodes can be connected in strings for use in deep well environments. This anode installation is 1000mm apart in the middle, and the length of the tail anode is 20 meters and 50 meters. The tubular anodes supply protective current to counteract corrosion stemming from water chemistry, microbial activity, or soil contact.
In summary, MMO titanium tubular anodes offer versatile, highly engineered corrosion prevention across critical infrastructure assets like wharf steel piles, deep-sea platforms, small tank farms and deep well. As infrastructure ages globally, MMO tubulars will see increasing prominence to combat corrosion threats and sustain asset integrity.
