Magnesium Anodes are engineered to deliver highly efficient sacrificial corrosion protection for steel structures used in cathodic protection systems. Known for their high driving potential, they provide reliable and long-lasting protection in low-resistivity soils, freshwater, and underground environments.

Installation Steps
- Determine the required anode size and type based on soil resistivity and structure protection needs.
- Excavate a pit or trench at the specified distance from the structure to be protected.
- Prepare a backfill mixture (typically gypsum, bentonite, and sodium sulfate) if using packaged anodes.
- Place the magnesium anode in the trench or pit, ensuring the lead wire is positioned toward the structure.
- Connect the anode lead wire to the structure using approved welding or mechanical connection methods.
- Verify electrical continuity and measure the open-circuit potential before backfilling.
- Backfill carefully with native soil or prepared backfill, compacting gently to ensure good soil contact.
- Test the system after installation to confirm proper cathodic protection performance.
Common Applications
- The magnesium anodes are implied where there is the soft water or moderate hard water.
- When there is no sulphur present in the water.
- When there is need of maximum corrosion protection in standard residential setups.
- Water Pipelines: Provides cathodic protection for underground steel and ductile iron pipelines
- Storage Tanks: Ideal for protecting buried and above-ground steel storage tanks from corrosion
- Oil & Gas Industry: Used to safeguard steel pipelines, fittings, and buried infrastructure
- Residential & Commercial Plumbing: Prevents corrosion in water heaters and metal plumbing
systems
- Marine Structures: Helps protect docks, piers, and submerged metal components in
low-conductivity waters
