3S3 High Purity Magnesium Anodes Sacrificial Anode Metal Mg 1.36kg

S Type Long Lasting High Potential Magnesium Anode For Cathodic Protection
 
Introduction:

In the actual use process, the actually measured working potential is between -1.8v and -1.85v, so it can provide effective protection for the target structure. High potential magnesium anodes are recommended in soils with a resistivity greater than 8000ohm.cm.

How magnesium anodes work:

Magnesium anodes protect steel through sacrificial electrochemistry. Magnesium is negatively charged relative to steel. When the magnesium rod is connected to the steel tank by electrical conductors, the steel tank is then filled with water, and an electric current will continuously flow through the water between the magnesium rod and any exposed steel areas on the wall. The circuit is completed back to the magnesium rod through the water tank. This protective current is generated by magnesium releasing ions, which can lead to corrosion in the anode area. This type of galvanic protection is called "sacrificial"; the magnesium rod (anode) corrodes rather than the can (anode). This principle of electrolytic corrosion control is called "cathodic protection".

Application:

Magnesium anode is the use of magnesium negative potential, its potential is lower than steel, can be used to protect onshore pipelines and other buried structures, such as oil pipelines, natural gas pipelines, underground oil tanks, oil platforms, water heaters, and for the protection of fresh water ships in the environment.
