Composition and Design of MMO Tubular String Anodes
Core Materials and Construction
The MMO Tubular String Anode is meticulously crafted to deliver superior performance in challenging environments. At its core, the anode utilizes a titanium substrate, specifically ASTM B-265 Grade 1 titanium, known for its exceptional corrosion resistance and durability. This base material forms the tubular structure, typically with a wall thickness of 0.9mm, providing a robust foundation for the anode.
The distinguishing feature of the MMO Tubular String Anode lies in its coating system. The titanium substrate is coated with a layer of Mixed Metal Oxides, often a combination of ruthenium-iridium or iridium-tantalum oxides. This coating is applied through advanced processes such as electrodeposition, thermal decomposition, or plasma spraying, ensuring a uniform and adherent layer that maximizes the anode's electrochemical properties.
Customizable Dimensions and Specifications
One of the key advantages of the MMO Tubular String Anode is its adaptability to various project requirements. The standard specifications often include a diameter of 25mm and a length of 1000mm, but these dimensions can be customized to suit specific applications. This flexibility allows for optimal integration into diverse protection systems, whether for deep well anodes, bridge cathodic protection, or other specialized uses.
The anode's customizability extends to its electrical components as well. It typically comes equipped with a high-quality cable, often a 16mm² XLPE/PVC single-core cable with a length of 8 meters. This cable ensures efficient power transmission and easy integration into existing cathodic protection systems.
Performance Characteristics
The MMO Tubular String Anode is engineered to deliver exceptional performance over an extended period. With a standard output current of 8A and a design life of 20 years (which can be customized), these anodes offer a reliable and long-lasting solution for corrosion protection. The combination of the titanium substrate and the MMO coating results in an anode that can withstand harsh environments while maintaining its electrochemical efficiency.
The coating system plays a crucial role in the anode's performance. The mixed metal oxides provide a catalytic surface that facilitates efficient electron transfer, reducing the energy required for electrochemical reactions. This efficiency translates to lower operational costs and improved overall system performance for MMO Tubular String Anode OEM products.
