Products Description
MMO linear anodes, also known as mixed metal oxide linear anodes or flexible anodes, are specifically designed to provide cathodic protection, especially where a low current, evenly distributed system is required. 12 These anodes are used in cathodic protection systems to prevent corrosion of metal surfaces in structures such as pipelines, storage tanks, and other underground or underwater metal structures.
In addition, the design of the MMO linear anode effectively eliminates interference from nearby structures and stray currents. This property not only increases its effectiveness in mitigating corrosion, but also makes it a reliable choice for a variety of applications. Its design embodies a balanced combination of practicality and performance, making it a noteworthy solution in the anti-corrosion sector.

Products Composition
Composition
MMO (Mixed Metal Oxide) Linear Anode is a technologically advanced component designed for optimal performance in a variety of applications. Crafted with precision and an understanding of electrochemical processes, it features a combination of materials that enhance its functionality, durability and resistance to challenging environments. Here are the key elements that make up its composition:
Core:
The core of it is a core made of high-quality titanium wire. The core is carefully coated with a catalyst mixture derived from mixed metal oxides, the main components being iridium and tantalum oxides.
Coating:
MMO coatings are characterized by their unique dual functionality. On the one hand, it contains electrocatalytic conductive elements that act as catalysts to drive the fundamental reactions that generate electricity. On the other hand, it is embedded with a massive oxide that acts as a protective shield, ensuring that the base material remains corrosion-resistant.
Acid-resistant fabric:
This special fabric is designed to provide an extra layer of protection against acidic environments. Its unique composition ensures that MMO linear anodes are protected from the potentially corrosive effects of acids, thereby extending their service life.
Protective braid:
A protective braid surrounds the anode to provide mechanical protection. This strong braid protects the anode from external wear and tear, making it more durable and resistant to external forces.
Coke Breeze:
Coke Breeze plays a key role as backfill material. It not only enhances the conductivity of the anode but also helps distribute the current evenly. This ensures efficient operation and reduces potential hot spots.
