A steel rope series magnesium alloy sacrifice anode was installed underground
The high potential magnesium anode manufactured by our company is made of high quality and high purity magnesium material, which conforms to ASTM97-98 standard. The anode has excellent electrochemical performance by using specific production process. In the process of cathodic protection, the anode consumption is uniform, so the service life is longer. In the actual use, the actual measured working potential is between -1.8V and -1.85V, so the protection effect on the target structure is more obvious. High potential magnesium anodes are recommended for soils with a resistivity greater than 8000 ω. Cm. Because it is cheaper than the high potential anode, it can reduce the cost and effectively prevent the hydrogen evolution reaction in the protected metal structure due to overprotection.
Magnesium alloy sacrificial anode A metal installation used for working in soil, fresh water, and seawater, with an anode to protect a trapezoidal, D-shaped, rod-shaped (cylindrical, rectangular) magnesium anode that is produced by extrusion. Chemical composition, electrochemical performance, steel core and other surface quality are in line with national standards.
