Product Description

Sacrificial magnesium anode manufacturer

magnesium anodes come in all shapes and sizes. The magnesium in a packaged anode weighs from 1 pound to 50 pounds. The most commonly used anode in worldwide is a 17 pound anode. With 28 pounds of powdered backfill packed around the magnesium, a packaged 17 pound anode weighs about 45 pounds. It comes with 10 feet or 15 feet of #12, insulated solid copper wire. The backfill consists of 75% powdered gypsum, 20% powdered bentonite clay and 5% sodium sulfate. This mixture is a low cost, nonhazardous, electrically conductive earth backfill. 

A cotton bag holds the backfill around the inner metal bar. It decomposes over time in the ground. The anode is shipped in an outer disposable, plastic or paper bag to protect it from rain or snow. It is recommended that 5 gallons of water be poured on the anode after it is placed in the earth to wet the backfill. This lowers the resistance between the magnesium and the earth causing more electric current to flow. This provides more protective current than would be possible in dry soil.



Hp Magnesium anodes are produced in a variety of shapes and sizes for use in anti-corrosion protection of such projects are oil pipelines, gas pipelines, water supply pipes and drain-pipes, underground cables, chemical plants, communication, harbors, watercrafts and reservoir strobe.

Q. What do Magnesium sacrificial anodes do?

A. Magnesium anode is used in the technical method of electrochemistry cathode protection. theory is from that connect with the protected metal body ,with the exhausting and dissolving of negative metal material or alloy ,protective curer body will be protected from corrosion . Mg anode can produce higher quality potential power, is ideal sacrificial materials.
