Extruded Magnesium Anode Rod are mainly used in waterboiler,
heatexchanger, vapourater, boiler,etc.lt has pro-perty of
softingwater,de-dirtresidual,enlong the usinglife,span.
Adventages:
(1) Corrosion protection,
(2) protect water heater, water containers of steel structure,
(3) protect the gas pipeline in-home service polarization high
resistance electrolytes (soil and water in the steel structure)
