Extruded Magnesium Anode Rod for Water Heater

Magnesium Anode for tank cathodic protection. Application: water boiler, heat exchanger, vopourater, water container, etc.

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)
