Product introduction  

Magnesium alloy sacrifice anodes are produced according to the national standard GB/T17731-2004 "Magnesium alloy Sacrifice Anodes", and the anodes used for pipelines are also in line with SY/T0019-97 "Design Code for Cathodic Protection of Sacrifice Anodes for Buried Steel Pipelines".  

Our magnesium alloy sacrificial anodes are widely used in oil pipelines, natural gas, gas pipelines and storage tanks.  Ports, ships, submarine pipelines, drilling platforms;  Airport, parking lot, bridge, power plant, municipal construction, water treatment plant, petrochemical plant, smelter, gas station corrosion protection and water heater, heat exchanger, evaporator, boiler and other equipment.  

The product has the following characteristics:  

(1) Small specific gravity and negative potential.  

(2) The driving voltage for iron is high and the current efficiency is low.  

(3) Large generating capacity per unit mass and long service life.
