Product Description
High Potential Magnesium Sacrificial Anode for High Resistivity Dry Sandy Soil
This high potential magnesium sacrificial anode is specifically engineered to deliver dependable cathodic protection in high resistivity soil environments including dry, sandy, and rocky terrains. With an open circuit potential of -1.70 to -1.75V (vs Cu/CuSO4), magnesium anodes provide the highest driving voltage among sacrificial anode materials, making them the ideal choice for soil conditions where zinc and aluminum anodes cannot generate sufficient protective current.
Why Magnesium Excels in High Resistivity Dry Sandy Soil
- Highest Driving Voltage: Magnesium generates 1.70-1.75V driving potential, 30-40% higher than zinc anodes, ensuring effective protection even in soils exceeding 5,000 ohm·cm resistivity
- Superior Current Output: In dry sandy soils with limited moisture and electrolyte conductivity, magnesium anodes maintain stable current output levels, preventing corrosion where passive anode materials become ineffective
- Low Polarization Rate: Magnesium anodes resist passivation and maintain active discharge even in sandy and rocky soils with poor electrolyte contact
- Proven Track Record: Extensively deployed in desert pipeline projects, mountainous rocky terrain, and arid region storage tank farms with consistent long-term protection results
Soil Resistivity Application Guide
| Soil Resistivity Range | Recommended Anode | Expected Performance |
|---|---|---|
| <1,000 ohm·cm | Zinc or Aluminum | Standard protection |
| 1,000-3,000 ohm·cm | Magnesium (AZ63) | Good protection |
| 3,000-10,000 ohm·cm | High Potential Magnesium | Optimal protection (dry/sandy/rocky soil) |
| >10,000 ohm·cm | Impressed Current System | Consider alternative |
