Aluminum Anodes For Harbor


About product

Aluminum Anodes are widely recognized as the most prevalent and effective solution for the cathodic protection of harbors. These sacrificial anodes, also referred to as galvanic anodes, are specifically designed to mitigate corrosion and extend the lifespan of harbor structures. The most commonly used material for these anodes is aluminum alloy, which exhibits an impressive electrochemical capacity of approximately 2500 Ah/kg, depending on the specific composition and production method.

Product Detail

Harbor anodes typically have a current output capacity ranging from 2 to 3 A each, operating at a driving voltage between 0.25 and 0.3 V. To ensure comprehensive protection, sacrificial anodes are evenly distributed across the structures to be safeguarded and mounted with continuous, persistent metallic contact. This strategic placement facilitates the efficient flow of protective currents, effectively preventing corrosion and maintaining the structural integrity of harbor installations. With a typical design lifespan of 20 to 30 years, aluminum anodes provide long-term corrosion protection, reducing maintenance requirements and associated costs while ensuring the durability and longevity of harbor infrastructure.

The use of aluminum anodes in harbors underscores their reliability, efficiency, and durability in combating corrosion. By employing these anodes, harbor authorities can effectively safeguard their structures against the corrosive effects of the marine environment, ensuring the continued functionality and safety of these critical maritime facilities for years to come.
