Product profile

  MAGNESIUM ANODE

1) Commodity:   Casting Magnesium Anode

2) Standard:  ASTM-97

GB/T 17731-2004 Magnesium sacrificial anode

SY/T 0019-97 Buried steel pipeline sacrificial anode catholic protection standard

3) Packing: Extrude rod mg anode is in wooden case, cast mg anode on wooden pallet wrapped with plastic

Standard exported package , suit for long time sea transport

4) Advantages and usages:

Magnesium anode is used in the technical method of electrochemistry cathode protection. theory is from that connect with the protected metal body ,with the exhausting and dissolving of negative metal material or alloy ,protective curer body  will be protected from corrosion . Mg anode can produce higher quality potential power, is ideal sacrificial materials.

Magnesium anode is used in ship equipment and building, port construction, sea project, underneath pipeline, petroleum chemical fields.

Extruded magnesium anode is mainly used in water boiler, heat exchanger, evaporimeter, and boiler and so on. It has properties of softing water, de-dirt residual ,en-longing the working life of container.
