Quality Substrate Material
Our magnesium ribbon anode is produced using high-purity magnesium, conforming to ASTM B843 – M1C standards.
High Current Output
This extruded magnesium ribbon anode has an increased surface area-to-mass ratio. With a high driving potential of -1.7V to -1.75V (CSE), it can generate more current than their cast magnesium counterparts. Generally, the current output is three to seven times greater than that found with cast anodes of the same weight.
|Open Circuit Potential (-V)||1.7 – 1.75|
|Close Circuit Potential (-V)||1.58 – 1.62|
|Current Density||Soil: 3 mA/ft. (10 mA/m) / Freshwater: 0.9 mA/ft. (3 mA/m)|
|Current Capacity||500A.h/lbs (1100A.h/kg)|
|Current Efficiency||50% min.|
Remarks: Open/close circuit potential is with respect to a Saturated Calomel Reference Electrode.
Uniform Current Distribution
The magnesium ribbon anode is constructed with a solid galvanized steel core, which runs lengthwise through the anode to ensure efficient electrical discharge as current is evenly distributed along the length of the structure.
The magnesium ribbon anode is easy to bend and has a small footprint. It is mainly installed as a coil around the protected body, especially in cathodic protection for long-distance pipelines, crossing pipelines, large tanks or silos among other structures. It functions automatically after installation, so no frequent maintenance is required, and does not cause any harmful interference with the surrounding environment.
The magnesium ribbon anode is flat in shape, and our standard magnesium ribbon anode is manufactured in 3/4” by 3/8” flexible coils. A 0.135″ steel core wire is embedded in the length of anode and the ribbon anode weighs approximately 0.243 pounds per foot in length. The length can be adjusted upon request.
