If you replaced the magnesium anode
rod with a similar one, the problem has recurred.
A current through the earth can be easily produced by galvanic action from the energy of corrosion of a magnesium anode
Therefore, contact of magnesium with any other metal in the presence of an electrolyte can lead to attack of the magnesium, the severity depending on the ratio of the areas of the magnesium anode
and the dissimilar cathode (a low ratio means worse corrosion).
The magnesium anode
system was diligently monitored and depleted anodes were diligently replaced.
The latest electric water heaters contain built-in magnesium anode
rod descaling devices, which solves descaling problems.
Six-Year Warranty: The XR90 includes a patented magnesium anode
rod with a special resistor to protect the tank from rust.
This is done by installing a replacement magnesium anode
and connecting it to the gas line.
The PowerMag 1000 system, which is simple to install and easy to use, enables full control over low maintenance sacrificial magnesium anode
systems with no "over voltage" issues.
The voltage difference of the zinc or magnesium anode
and the pipe causes current to flow through the electrolyte and return through the metallic portion of the circuit.
Tenders are invited for Supply, Installation And Commissioning Of Magnesium Anodes
For Protection Of Hot Spots In Mainline Under Bkpl, Barauni Jurisdiction
The company offers same day shipping, low prices and the largest selection of Mil-Spec quality zinc, aluminum and magnesium anodes
The electrolyte is saltwater (ocean water can also be used) acting with magnesium anodes
, and carbon cathodes to produce electricity.
