HP Casting Magnesium Anode For Cathodic Protection

Product Detail

high potential casting magnesium anode


  Magnesium anode is the most common material used as sacrificial anode in cathodic protection system because of its higher driving voltage, easy installation and limited maintenance. It is typically used for buried transmission oil & gas pipelines, and also can be used to protect structures in fresh water. In addition to pipelines, magnesium anodes are often used to protect propane, water and chemical storage tanks, areas of ships and port facilities that are not in direct contact with sea water, power plants and irrigation systems.

  High Potential (HP) Cast Magnesium anode is the best choice for CP systems in high resistivity soil since it is made from the high purity magnesium which provides higher electrochemical and efficiency.

  

  The anode corrodes instead of the structure and must be replaced after a certain period of time that depends on the type of structure that is being protected, the size and grade of anodes that are used, and the corrosivity and resistivity of the surrounding soil.




Our Mg anodes all manufactured and tested according to latest international standards, such as ASTM B843 and ASTM G97, it is available from both M1C (high potential) or AZ63B (Std potential) alloy with annual capacity 8,000 metric tons.
High Potential (HP) Cast Magnesium anode is the best choice for CP systems in high resistivity soil since it is made from the high purity magnesium which provides higher electrochemical and efficiency.
