  • Suppliers for magnesium anode, water heater anode, mg

    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.

  • Galvanic anode

    A galvanic anode is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal structures from corrosion.. They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive electrochemical potential) than the metal of the structure.The difference in potential between the two metals means that the

  • SESCO Cathodic Protection and Corrosion Control CP

    The magnesium anode will corrode instead of the pipe; the magnesium alloy metal will be sacrificed to save the steel pipe. This is the purpose and the effect of cathodic protection. While magnesium anodes can be beneficial in slowing the rate of corrosion on a buried pipeline under ideal conditions, they do have their effective limitations.
