Description:
A magnesium anode is used as a sacrificial anode in cathodic protection. This magnesium sacrificial anode has high chemical activity, its electrode potential is rather negative, and the driving voltage is quite high.
Advantage:
1.Anode assembly with cable, backfill, epoxy resin seal and packaged in a cotton bag.
2. Recyclable and easily decomposable materials.
3.Environmentally safe. Harmful elements in backfill lower than specified allowable limits.
Application:
Magnesium anodes are effective and affordable for Anticorrosion of buried pipeline buried pipeline, onshore platform, huge boiler and steel structures in salt and fresh water, Including: Hulls of ships and various other boats
Water storage tanks
Piers, docks, and wharfs
Pipelines
Heat exchangers
