usage

 

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.   

 

Production standard: 

Standard : ASTM G-97
