Factory supply ASTM B843 Industry Standard for M1C high potential magnesium anodes
1.Product information
• Item name: Magnesium sacrificial anode
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.
When the anode's cable is attached to a pipeline or other underground structure, a galvanic cell is created in which electrons flow from the anode to the structure, thereby protecting the structure.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.
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.
2.Application of sacrificial anode magnesium
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.
