What is Mmo Anode Plate?

MMO (Mixed Metal Oxide) anode plates are widely used in various industries for cathodic protection applications. They provide effective and long-lasting protection against corrosion in a wide range of environments.Customers of precious metal oxide composite-coated titanium electrodes can choose and customize them according to their own needs. The length of the anode can be customized according to customer requirements.

The MMO anode plate offered by TJNE are known for their high quality and excellent performance. Our products are designed with precision, using advanced technology and quality materials, ensuring reliable and efficient corrosion protection.

Working Principle and Chemical Performance

MMO anode plates work based on the principle of electrochemical reactions. The mixed metal oxide coating on the surface of the anode releases electrons, which then pass through the electrolyte and onto the cathode, preventing the corrosion of the protected structure.

System Composition and Structure

The Mmo Anode Cathodic Protection consist of a titanium substrate with a mixed metal oxide coating. The coating is carefully applied to achieve optimal performance and adhesion to the titanium substrate. The plates are available in various sizes and shapes to suit different applications.

Applications

Mixed metal oxide (MMO) anode plates have become an important material technology for corrosion prevention across industrial sectors like oil and gas, marine, water infrastructure, and chemical/petrochemical. Suitable for cathodic protection projects in different environments, such as sea water, fresh water, and soil media.

● Oil and gas

In the oil and gas industry, MMO anode plates are commonly used for cathodic protection of transmission pipelines, offshore rigs, processing equipment, and storage tanks. By applying a small electrical current, the MMO anodes provide sacrificial corrosion protection that preserves infrastructure integrity and prevents leaks or failures. This is especially critical for pipelines and assets exposed to seawater or corrosive soils.

● Marine structures

For marine applications, MMO anode plates are attached to the hulls and submerged metallic surfaces of ships, tankers, and offshore platforms to mitigate corrosion in seawater. This prevents damage from galvanic and electrolytic corrosion processes that can compromise hull integrity and lead to structural issues. MMO's high current output and resistance to seawater reactions provide optimal cathodic protection.

● Water and wastewater treatment

In water and wastewater systems, MMO anode plates installed in storage tanks, clarifiers, and pipelines neutralize corrosion due to water chemistry. This prevents asset degradation and also avoids contamination from corrosion byproducts leaching into potable water. Wastewater infrastructure also relies on MMO for corrosion control.

● Pipelines

MMO anode plates additionally protect above-ground storage tanks used in the chemical, oil and gas sectors for corrosive products like crude oil, acids, and solvents. The anodes are designed to withstand tank contents and prevent external corrosion.

● Above-ground storage tanks

For buried metallic pipelines carrying corrosive liquids like seawater, wastewater, or acids, MMO anodes buried along the pipeline route provide critical corrosion protection to maintain integrity and prevent spills. The MMO materials are specially engineered to function in underground environments.

In summary, MMO anode plates serve a vital role in corrosion prevention across critical infrastructure in marine, offshore, chemical, petrochemical, and water/wastewater industries where asset integrity and reliability are paramount. MMO’s efficacy, versatility, and engineering design make it an essential technology for cost-effectively combatting corrosion and its safety, environmental, and economic consequences. As infrastructure ages and corrosion threats grow globally, MMO anodes will continue seeing expanded use and evolution.
