High Purity Magnesium Sacrifical Anode For Corrosion Protection
Introduction:
Magnesium alloy sacrificial anode is the use of magnesium with a negative potential, which is lower than that of steel, and is used in oil pipelines, natural gas pipelines, underground oil tanks, oil platforms, water heaters, etc.
Magnesium alloy sacrificial anode features: good protection performance, easy installation, automatic operation after installation, no maintenance, no external current, low engineering cost, easy replacement, etc. Magnesium alloy anode is an ideal cathodic protection method.

Applications:
Magnesium alloy sacrificial anode is an ideal sacrificial anode material, suitable for soil and fresh water media, because of its negative potential, which is lower than that of steel, with extremely high electrochemical performance, uniform anode consumption, long life and large power generation per unit mass. Cathodic protection of metal structures, used in oil pipelines, natural gas pipelines, underground oil tanks, oil platforms, water heaters, etc.
