Product Detail

Marine Zinc Anodes – Zinc Anode For Ship Hull

Marine zinc hull anodes are specifically designed to provide effective corrosion protection for ship hulls. These marine zinc anodes serve as sacrificial components that are strategically attached to the hull surface.

The purpose of the hull anodes is to sacrifice themselves through corrosion instead of the ship’s hull. This sacrificial action helps prevent the hull from corroding in the harsh marine environment. As the marine zinc anodes corrode, they release electrons into the surrounding water, creating a cathodic protection mechanism.

The Features Of Zinc Bolt-on Hull Anodes

  • Small Autolysis: The bolt-on type marine anodes exhibit minimal self-consumption (autolysis) during the corrosion process. This means that the anodes maintain their shape and integrity for an extended period, ensuring consistent and effective corrosion protection.
  • High Current Efficiency: Marine zinc anodes have a high current efficiency, meaning they effectively release electrons into the surrounding seawater during the corrosion process. This efficient current transfer enhances their protective capabilities.
  • Excellent Self-Regulating Property: The hull anodes possess a self-regulating property, meaning they adjust their corrosion rate according to the environmental conditions and the level of protection required. This ensures optimal and balanced corrosion protection without the risk of over protection.
  • Long Protection Period: These marine anodes offer a long protection period, typically lasting for 20 to 30 years or even longer, depending on the specific conditions. This extended lifespan reduces the frequency of anode replacement and maintenance, providing cost savings and convenience.
  • No “Over Protection” Phenomenon: Marine zinc anodes are designed to prevent the occurrence of “over protection.” Over protection can happen when anodes release excessive amounts of electrons, leading to damage or accelerated corrosion of the protected structure. The self-regulating property of these anodes helps maintain a balanced and controlled corrosion rate, avoiding such issues.
