Sacrificial Anode Protection For Vessel

ASTM Sacrificial Magnesium Anode for Vessel / Marine / Ships / Drill Rigs

ASTM G-97 Magnesium Anode

Product Introduction:

Magnesium anodes are used in such systems, most commonly to protect underground gas, oil and water pipelines.
Magnesium anodes come in two alloys. H-1 or AZ-63 is 90% magnesium, 6% aluminum and 3% zinc. The zinc and aluminum lowers the cost of the anode but it also lowers the driving potential to about -1.55 volts referenced to a copper sulfate electrode. It will perform well in corrosive soil if the tank is well coated and will last longer than the high potential alloy. The other alloy is 99% pure magnesium. It is called a "high potential" anode as its open circuit potential is as high as -1.80 volts. It works better than the H-1 alloy anode in dry or resistant earth or where more current is needed because of a poorly coated tank. The higher potential forces more current to flow than would from an H-1 alloy anode. It costs more per pound but in many cases it is worth the extra cost.

Specifications:

High Potential (HP) Cast Magnesium anode is the best choice for CP systems in high resistivity soil since it is made from the high purity magnesium which provides higher electrochemical and efficiency.
