High-performance magnesium anode from KIG Tech for pipeline & offshore cathodic protection.
Magnesium anodes are the preferred sacrificial anode for protecting buried pipelines, storage tanks and offshore structures in high-resistivity soils. As part of a complete cathodic protection system, they deliver a highly negative driving potential that forces the protected steel to become the cathode of the electrochemical cell.
When coupled to a steel structure, the magnesium unit corrodes in place of the protected metal. Unlike an ICCP system that relies on an external power source, passive magnesium, zinc anode and aluminum anode units operate without electricity, making them ideal for remote or maintenance-light installations.
| Parameter | Typical Value |
|---|---|
| Driving potential | -1.55 V vs CSE |
| Efficiency | 50 percent |
| Typical alloy | AZ63 / High Potential |
| Soil resistivity | Greater than 1000 ohm-cm |
| Service life | 10 to 20 years |
For higher current demand, pair these anodes with an MMO anode or an ICCP system. Our FRP pultrusion and fiberglass grating structures are frequently specified for the same marine and chemical environments where corrosion control is critical.
