ICCP is an active corrosion control method that uses an external DC power source (rectifier) to drive a protective current from an inert anode to the structure being protected. This system is highly controllable and adaptable, making it the preferred choice for large-scale, complex, or high-resistivity environments where sacrificial anodes are impractical.
Anodes: Inert materials (like MMO, High Silicon Cast Iron) that introduce the protective current into the electrolyte.
Rectifier: Converts AC power to the required DC current, allowing for precise control of the protective output.
Cables and Connections: Insulated wiring to connect the rectifier to the anodes and the structure.
Reference Electrodes: Used to monitor the potential of the protected structure to ensure adequate protection levels.
The rectifier allows for precise adjustment of the protective current to compensate for changing environmental conditions (e.g., seasonal changes in soil resistivity).
ICCP systems can deliver high current outputs, making them ideal for protecting extensive assets like long pipelines, large storage tanks, and offshore platforms.
ICCP anodes, particularly MMO anodes, are made from highly durable, low-consumption materials, offering service lives often exceeding 20 years.
The high driving voltage from the rectifier allows the system to overcome challenges posed by high soil or water resistivity, where sacrificial anodes would fail.
We specialize in various ICCP anode materials and configurations to suit diverse applications, with Mixed Metal Oxide (MMO) anodes being the most versatile and popular choice.
| Anode Type | Core Material | Primary Application | Key Feature |
|---|---|---|---|
| MMO Tubular Anodes | Titanium Substrate with MMO Coating | Deep well groundbeds, water tanks, marine structures | High current output, low consumption rate, long life. |
| MMO Ribbon Anodes | Titanium Substrate with MMO Coating | Reinforced concrete, internal pipe protection | Flexible, uniform current distribution. |
| MMO Canister Anodes | MMO Anode in a Steel Canister with Coke Backfill | Shallow and deep groundbeds | Easy installation, pre-packaged for optimal performance. |
| High Silicon Cast Iron (HSCI) | Fe-Si Alloy | Conventional groundbeds, freshwater | Cost-effective, robust material. |
