What is MMO Canister Anode

The MMO Canister Anode is a high-performance anode solution designed for various corrosion protection applications. It is manufactured by TJNE, a leading provider of MMO anode products. With strong technical expertise, comprehensive after-sales service, complete certification and testing reports, fast delivery, and secure packaging, TJNE is your reliable partner.

The Mixed metal oxide Canister Anode is a cylindrical anode made from a titanium substrate coated with a mixed metal oxide (MMO) catalyst. It is specifically designed to provide efficient and long-term corrosion protection in various environments.

Working Principle

The Mmo Canister Anode operates based on the principle of impressed current cathodic protection (ICCP). It utilizes the electrochemical reactions between the MMO catalyst and the surrounding electrolyte to generate a protective current that counteracts corrosion on metallic structures.

Chemical Performance

The mixed metal oxide catalyst on the Mixed metal oxide Canister Anode provides excellent chemical stability and catalytic activity, ensuring a long lifespan and high corrosion protection efficiency. It has superior resistance to chlorine and other aggressive substances commonly found in corrosive environments.

Application

It finds applications in various industries, including:

Mixed metal oxide (MMO) canister anodes have become an important cathodic protection technology to mitigate corrosion across industrial infrastructure sectors like oil/gas, marine transport, chemical facilities, and municipal assets.

Oil and gas

A major application is safeguarding buried pipelines in the oil and gas industry. It is buried adjacent to underground pipelines and provides protective current flows that counter pipeline corrosion from soil elements. This sustains pipeline integrity and prevents leaks or failures.

Marine structures

In marine settings, It is fastened to the submerged sections of ships, offshore rigs, and port structures to generate cathodic protection current to protect against seawater corrosion damage to propellers, rudders, mooring devices, and other underwater assets.

Above-ground storage tanks

For above-ground storage tanks containing corrosive substances like brine or acids, Mixed metal oxide canister anodes attached to tank surfaces neutralize external corrosion by supplying protective current to shielded areas. This maintains tank integrity and prevents environmental contamination.

Water treatment facilities

At water and wastewater plants, It is installed in clarifiers, sludge collectors, and pipelines to provide corrosion protection for buried steel assets vulnerable to corrosion from moisture and microbial activity. This prevents asset degradation and the leaching of contaminants.

Reinforced concrete structures

In reinforced concrete structures like piers, pilings, and bridges, Mixed metal oxide canister anodes embedded during construction deliver a protective current that reinforces steel rebar from corrosion promoted by chloride penetration. This prevents costly structural repairs.

With its robust design and mounting versatility, It offers flexible integration for corrosion protection across key infrastructure. As assets age worldwide, MMO canisters will see expanded usage to combat corrosion threats in critical marine and onshore applications.
