โšก Professional Cathodic Protection Solutions

Magnesium Anodes

Magnesium anodes for cathodic protection projects where a higher driving voltage is required in medium to high resistivity soil.

PRODUCT OVERVIEW

Electrochemical Performance

Magnesium anodes provide a high driving voltage compared with common sacrificial anode materials, making them suitable for many soil-side cathodic protection applications.

๐Ÿ”‹ Standard Potential (H-1)

Manufactured in accordance with ASTM B843-AZ63B standard, containing 90% magnesium, 6% aluminum and 3% zinc. Ideal for soil conditions where resistivity is under 3,000 ฮฉยทcm with driving potential of -1.55 volts.

โšก High Potential (HP)

Manufactured from high-purity magnesium according to ASTM B843-M1C alloy references. Open circuit potential can reach approximately -1.7 volts, depending on material and test conditions, supporting applications in high-resistivity environments.

APPLICATIONS

Versatile Solutions

Typical Applications of Magnesium Sacrificial Anodes across multiple industries and environments.

๐Ÿ—๏ธ Underground Pipeline Protection

For protecting underground pipelines in soils with medium to high resistivity. Standard potential anodes are commonly used in lower resistivity soils, while high potential anodes are commonly selected for higher resistivity environments.

๐Ÿ›ข๏ธ Storage Tank Bottom Protection

Installed beneath above-ground storage tank bottoms to prevent corrosion, suitable for both new construction and retrofit projects. High potential anodes provide enhanced protection in challenging soil conditions.

๐Ÿšฟ Water Heater & Tank Protection

Internal protection for water heaters, boilers, and water tanks. Magnesium anodes provide effective galvanic protection in freshwater applications.

๐Ÿ”Œ Buried Cable Protection

Corrosion prevention of metallic sheaths for buried cables in various soil conditions. The high driving voltage of magnesium makes it effective even in challenging environments.

โ›ฐ๏ธ High-Resistivity Soil Applications

Particularly effective in sandy, rocky, or mountainous areas where soil resistivity exceeds 2,000 ฮฉยทcm. High potential magnesium anodes deliver superior performance in these challenging conditions.

โšก Grounding System Protection

Protection of grounding rods, anchor bolts, and valve boxes. Magnesium anodes provide reliable long-term protection for critical infrastructure components.

๐ŸŒŠ Specialized Marine Applications

While primarily designed for soil applications, certain magnesium formulations can be used in specific marine environments where galvanic protection is required.
