♦ Specifications
High Potential Magnesium anode is used as a sacrificial anode in cathodic protection. Magnesium has the highest driving voltage of all the materials used for sacrificial anodes. if it is placed within a system that uses large amounts water, it attracts the corrosion away from other components.
Our magnesium anode all manufactured and tested according to latest international standards, such as ASTM B843 and ASTM G97,It’s available from both M1C( high Potential)or AZ63B(standard Potential)magnesium anode.
♦ Application :
High Potential Magnesium anode fight corrosion effectively and economically, and are commonly used in marine environments, soil environment,etc..They protect a variety of steel structures in salt, brackish and fresh water, including: Buried Oil gas Pipelines, Storage tanks, Boats, Ballast tanks, Bulkheads, Pilings, Heat exchangers, etc.
² Boats ² Ballast tanks ² Bulkheads ² Water storage tanks
² Pilings ² Pipelines ² Heat exchangers
Magnesium anodes corrode much more easily than the materials they are protecting, drawing the corrosion away from equipment.
