Pipe design for cathodic protection magnesium anode. Zinc anode.

Magnesium anodes are suitable for oil pipelines in underground fresh water. Gas pipelines. Reservoir gates. Used in condenser equipment. Magnesium alloy anodes are commonly used in soils. Zinc alloy anodes are suitable for soils with low resistivity and moisture. Aluminum anodes generally have very low resistivity. Wet environment is more suitable for aluminum anode performance.
