UCORR® High Efficiency Cast Iron Anode (Torus Anode)

Conventional cast iron anodes utilized in Impressed Current Cathodic Protection (ICCP) anode groundbeds are typically cylindrical (solid or hollow). These anodes are manufactured in various sizes such as 2”x60” and 3”x60”, with 3”x60” being the most commonly used.

Anode current capacity is directly related to surface area in contact with electrolyte. Therefore, increased anode surface area yields increased anode current output. The only ways to increase the surface area of a cylindrical anode are to increase the diameter and/or length. However, increasing anode diameter/length will increase the cost of production as more alloy materials are required. Consequently, transportation and installation costs will increase dramatically as the size and weight of the final product increases.

Another way to increase the anode current capacity is to increase the surface area in contact with the electrolyte by redesigning the anode shape. The surface area of Ucorr® High Efficiency Cast Iron (HECI) Anode is much greater than conventional anodes due to its innovative shape. Additionally, new casting methods are utilized which eliminate production defects of HECI anodes in the foundry process.

The Ucorr® HECI anodes have successfully been installed and tested in numerous projects. References are available upon request.
