Magnesium alloy sacrifice anodes are supplied by our company with various specifications of magnesium alloy sacrifice anodes.

Magnesium anode: short for magnesium alloy sacrifice anode, also known as magnesium alloy anode, magnesium sacrifice anode. Used in cathodic protection system, it is an important equipment and material to prevent electrochemical corrosion.

Magnesium alloy sacrifice anode is widely used in oil pipeline, natural gas, gas pipeline and storage tank; 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 description

Common magnesium alloy sacrificial anode

Magnesium alloy sacrifice anodes are produced according to 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, 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.

High potential magnesium alloy sacrifice anode

The high potential magnesium anode developed and produced by our company is made of high quality and high purity magnesium material. The product conforms to ASTM97-98 standard. The anode has excellent electrochemical performance by using specific production process. In the process of cathodic protection, the anode consumption is uniform, so the service life is longer. In the actual use, the actual measured working potential is between -1.8V and -1.85V, so the protection effect on the target structure is more obvious. High potential magnesium anodes are recommended for soils with a resistivity greater than 8000 ω. Cm. Because it is cheaper than the high potential anode, it can reduce the cost and effectively prevent the hydrogen evolution reaction in the protected metal structure due to overprotection. 2.
