Product description

Magnesium Anode Bag 17lb/45lb 1.7V, INCL 32 ft. of 8 gauge 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. 

  • Net weight: 7.7 KG / 17lb
  • Gross weight: 20 KG / 45lb
  • Material: Magnesium
  • Cable: AWG 8, insulated copper wire. Can easily be shortened to desired length
  • Type: High Potential, 1.7V, M1C
  • Cast specs: 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 different qualities being used: standard potential (1.5V) and high potential (1.7V).
When the anodes are designated for underground installation, we delivered them 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 for extra long durability and current discharge reasons. 

Our Magnesium anode bag for underground tanks:

  • Protects your underground propane tank from corrosion (cathodic protection)
  • Includes canvas bag, metal particle filling, and connection wire
  • 1 bag for 500 gallon tank, 2 bags for 1000 gallon tank
  • Bare weight 17lbs, with surrounding filling 40lbs

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 parched 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.

  • Q: How long does an anode bag last?

A: With optimal use, our anode bags can last for up to 5 years. However, the life expectancy may vary depending on environmental conditions, including the aggressiveness of the soil or the water in which they are placed. Regular inspections can help to assess the condition of the anode bag and the remaining service life.

Q: How to install an anode bag for a propane container?

  • A: Installation of an anode bag for a propane container involves several steps. First and foremost, the area around the container should be cleared. The anode bag is then placed in a hole excavated near the container. It is then connected to the container with a special cable, which ensures that the connection is firm and secure. The hole is then filled again, which ensures that the anode bag remains in contact with the surrounding soil.

Q: What are anode bags used for?

  • S: Anod bags are used for cathode protection. They protect various metal structures such as propane containers, underground pipes, buried steel resources, bridges, pier and fire posts against corrosion. By producing a small electric current, anode bags counteract the corrosive electrical activity that leads to rust and degradation.

Q: What is an anode bag?

  • A: An anode bag is a type of sacrifice anode used for cathode protection. It is a bag filled with a reactive metal, usually magnesium, which is connected to a metal structure to protect it from corrosion. When placed in the soil or water near the structure, it produces a protective electrical current that prevents the metal from corroding.
