Product description

Magnesium Anode Bag 4KG/9lbs 1.7V, INCL 32 feet of 8 AWG red XLPE/PVC cable

With the right amount of anodes, you can provide complete cathodic protection to your underground installation. Done correctly, this will provide immunity to corrosion for tanks, piping, sheet pilings, etc. Meaning that your underground object doesn't need to be changed because of corrosion for many years to come. 

For underground tanks, there are rules and regulations that require cathodic protection for underground tanks. Please refer to (USTs) Laws and Regulations on the United States Environmental Protection Agency's website.

  • Net weight: 4KG / 9lbs
  • Gross weight: 9KG / 20lbs
  • Cable: AWG 8, insulated copper wire. Can easily be shortened to desired length
  • Type: High Potential, 1.7V
  • Cast: cast to meet the American Society for Testing Materials (ASTM)Standard B843

Of all available anode materials, magnesium is the one that has the highest driven voltage. Because of this,
Magnesium anodes are used advantageously in soil and water with high resistivity.
Normally, there are two unique qualities being used: standard potential (1.5V) and high potential (1.7V).
When the anodes are intended for land installation, they are delivered as standard
with a backfill mix of bentonite, as well as 32ft long red XLPE / PVC 8 AWG cable.
The cable connection is embedded in epoxy.

  • Protect your underground propane tank
  • Includes canvas bag, metal particle filling, and wire to connect to the tank
  • Bare weight 9lbs, with surrounding filling 20lbs

Application recommendations
Anodes made from magnesium can protect underground tanks under most soil conditions. The High potential alloy is very effective. Based on conservative design assumptions, the table below provides recommendations for various tank sizes. This chart covers soil conditions up to 10,000 ohm-centimeter resistivity. Resistivities higher than 10,000 ohm-centimeter represent very dry soils. Verification of soil resistivity can be performed through soil analysis. If there is no effective external coating on the tank or soil resistivity exceeds 10,000 ohm-cm, contact us for design recommendations.
