ASTM High Potential Magnesium Anode 14D2-1 Sacrificial Galvanic Mg
Long Lasting High Potential Magnesium Anode For Cathodic Protection
Introduction:
High-potential magnesium anodes are produced using high-quality high-purity magnesium, and the products comply with ASTM97-98 standards. With a specific process, they have excellent electrochemical performance. During the cathodic protection process, the anode is consumed evenly, so it has a longer service life.
In the actual use process, the actually measured working potential is between -1.8v and -1.85v, so it can provide effective protection for the target structure. High potential magnesium anodes are recommended in soils with a resistivity greater than 8000ohm.cm.

Advantage:
Cathodic protection technology is to use a metal or alloy whose potential is more negative than the metal to be protected to be electrically connected to the metal to be protected, and rely on the current generated by the continuous corrosion and dissolution of the metal with a negative potential to protect others.
A: The one-time investment cost is low, and there is basically no need to pay maintenance costs during operation
B: The utilization rate of the protection current is high, and no over-protection will occur
C: No interference effect on adjacent underground metal facilities, suitable for plant area and long-distance pipeline without power supply, as well as small-scale decentralized pipeline protection
D: It has the function of both grounding and protection
E: The construction technology is simple and usually does not require special professional maintenance and management.
Application:
Magnesium anode is the use of magnesium negative potential, its potential is lower than steel, can be used to protect onshore pipelines and other buried structures, such as oil pipelines, natural gas pipelines, underground oil tanks, oil platforms, water heaters, and for the protection of fresh water ships in the environment.
