Cathodic Protection Anodes: Your Ultimate Corrosion Defense Solution

Understanding Cathodic Protection (CP)

Cathodic Protection (CP) is an electrochemical technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. This is achieved by supplying an external current to the metal structure, effectively stopping the natural corrosion process. CP anodes are the critical component that sacrifices itself or provides the necessary current to protect the target structure.

Key Types of Cathodic Protection Anodes We Offer

1. Sacrificial (Galvanic) Anodes

Sacrificial anodes are made from metals with a more negative electrochemical potential than the structure they protect (e.g., Zinc, Aluminum, Magnesium). They corrode preferentially, sacrificing themselves to protect the target metal. This system is simple, passive, and requires no external power source.

• Zinc Anodes: Ideal for marine environments (seawater) and buried structures with low resistivity.

• Aluminum Anodes: Used primarily in seawater and brackish water due to their high current capacity and efficiency.

• Magnesium Anodes: Best suited for buried pipelines and structures in high-resistivity soil.

2. Impressed Current Cathodic Protection (ICCP) Anodes

ICCP systems use an external DC power source (rectifier) to drive current through an inert anode to the structure being protected. This allows for greater control over the protective current and is suitable for large, complex structures or high-resistivity environments.

• Mixed Metal Oxide (MMO) Anodes: Highly durable, low consumption rate, and versatile for various environments (soil, water, concrete).

• High Silicon Cast Iron (HSCI) Anodes: Cost-effective for buried applications and freshwater.

• Platinum/Niobium Anodes: Used in specialized applications requiring high current density and long life.
