OEM ASTM ?Extruded Magnesium Anode Rod for ?waterboiler / heatexchanger / vapourater ? ?Extruded Magnesium Anode Rod for Water Heater Product Introduction:
?? ?Magnesium anodes are used in such systems, most commonly to protect underground gas, oil and water pipelines. ?

??

? ? 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.
Specifications:
Standard : ASTM G-97

Application:?
? ? The corrosion of metal in salt or fresh water or in soil can be prevented by the use of galvanic anodes in a cathodic protection system. ?Magnesium anodes are used in such systems, most commonly to protect underground gas, oil and water pipelines. ??
