ASTM Sacrificial High Potential Magnesium Anode Pre Packaged
Pre Packaged ASTM Sacrificial High Potential Magnesium Anode
♦ Specifications
High Potential HP Magnesium anode are made from high-purity magnesium, they could produce a higher driving voltage than conventional magnesium anodes, so high potential magnesium anodes are suited for structures buried in soils with resistivities in excess of 2,000 ohm/cm.
We adopt special technology, the anodes have superior electrochemical properties, in practical experience, the actual measured driving potential is between -1.8V to -1.85V, thus provide most powerful protection to the targeted structure. The anodes are consumpted uniformly, thereof the anodes have a longer working life.
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 HP 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.
Magnesium anodes corrode much more easily than the materials they are protecting, drawing the corrosion away from equipment.
