Simplified Installation
Many MMO electrodes are designed to facilitate their installation, such as anodes with pre-attached stirrups and flexible forms. Their easygoing installation, especially in tough access points or during constrained timelines, improves the projects and operations' efficiencies.
MMO electrode finds numerous applications in various industries. Here are some of them:
Marine Industry
The marine industry uses MMO electrodes predominantly in offshore oil and gas platforms, piers, ships, and underwater pipelines. They shield such structures from corrosion caused by saltwater, which is exceedingly aggressive to metals. They help maintain structural integrity and minimize expensive repairs in the marine environment.
Chemical and Petrochemical Plants
In chemical and petrochemical plants, structures such as storage tanks, vessels, and piping incur exposure to corrosive chemicals. Here, mixed metal oxide electrodes provide cathodic protection to these assets, thus extending their service life. They enable uninterrupted operations while increasing safety standards.
Ground Storage Tanks and Pipelines
These electrodes prevent corrosion in underground storage tanks and pipelines, which necessitate cathodic protection due to the corrosive nature of the soil. They promise that these systems have reliable protection while reducing the probability of leaks or failures. This is especially critical in industries dealing with hazardous fluids or gases.
Concrete Structures
MMO electrodes find wide utilization in providing cathodic protection for rebar in reinforced concrete structures. They installed either during construction or retrofitted into existing structures preserve bridges, parking garages, and buildings from corrosion. This maintains them in a sound condition and dramatically minimizes repair costs.
Renewable Energy Systems
These electrodes are employed in wind turbines and solar energy systems, which are frequently exposed to harsh environmental elements. They guarantee the metallic components of these systems are safeguarded from corrosion. This aids in increasing the longevity and dependability of renewable energy generation systems.
Industrial Facilities
Manufacturing and industrial facilities use these electrodes to protect piping systems, cooling towers, and other metallic structures from corrosion, which is caused by chemical exposure and moisture. They help reduce maintenance requirements while increasing operational efficacy.
Here are some things buyers can consider when choosing these electrodes:
Structure Type
Buzz applies electrodes for a type of structure, be it a pipeline, concrete, or marine. Their choice will depend on whether they are protecting a buried structure, an above-ground one, or an underwater installation. For example, ribbon anodes are ideal for concrete protection, while stirrup anodes suit pipelines.
Environment
The operating environment plays a huge role in electrode choice. Buyer should consider the corrosively level of the surrounding environment, like soil type for underground structures or water quality for marine applications. If the environment is too corrosive, they should go for electrodes with thicker MMO coating.
Current requirement
Buyers should ensure they go for electrodes with current output that will match their protection needs. To achieve effective cathodic protection, there should be a balance between current requirement and electrode size.
Installation
Since these electrodes will be installed in challenging conditions, buyers should consider how easy it will be to install them. They should settle for electrodes with pre-fabricated features such as stirrups or flexible designs that will simplify the installation process.
Compliance
Buyers should ensure they settle for these electrodes if there are any industry or regulatory standards since they will ensure the cathodic over-protection systems meet all the necessary requirements for performance and safety. In cases where there are both local and international standards, they should meet both of them.
Maintenance
Buyers should consider the maintenance requirements of these electrodes. The good thing is that MMO electrodes come with low maintenance requirements. They should also consider systems that will allow easy access to the electrodes in case maintenance is required.
MMO canister anodes mainly consist of a titanium core that has been electroplated with a mixed metal oxide coating. This titanium core offers immense structural strength and durability, while the mixed metal oxide coating is a resistant corrosion and lifespan extenderman. It is worth noting that the whole process makes them highly effective for cathodic protection in corrosive environments.
The amazing thing about these electrodes is that they are artificially created using a titanium layer that is electroplated with mixed metal oxides. Then, through electrochemical polarization, the cathodic protection current is generated. This current, in a practical sense, protects adjacent metal structures from corrosion.
Usually, the lifespan of these electrodes will depend on environmental conditions, current demand, and the quality of installation. However, on average, these electrodes will last anywhere between 20 to 30 years. In extremely corrosive environments, their lifespan can be reduced to 10 years. Luckily, it is possible to enhance their durability by ensuring optimum current output.
Apart from the initial installation, these electrodes don't require a buyer any form of maintenance. They are designed to be maintenance-free. They will keep providing cathodic protection without the need for periodic inspections. The electrodes will be built using durable materials that will inormally require little wear and tear to sustain them.
The first advantage that these electrodes come with is durability. For instance, they are manufactured using a titanium core. This makes them way more durable than zinc anodes. On top of that, they are also corrosion-resistant. While zinc anodes will have to be replaced frequently. These electrodes are designed to be long-lasting. They also offer lower maintenance costs.
