Magnetite anodes for impressed current cathodic protection
Magnetite anodes for impressed current cathodic protection, when constructed according to the design by Paul Bergsoee and Son A.B., overcome certain inherent disadvantages of magnetite (magnetic iron oxide) to afford low consumption at high current loads. More than 30,000 Bera Magnetite anodes have been put into operation. The anode is cast as an open cylinder with one end closed, approximately 800 mm (32 in.) long and 60 mm (2.4 in.) dia, with 40 mm (1.6 in.) ID. The inside is plated with copper, a copper plate is attached to the copper layer, and the anode cable is soldered to the plate, after which the anode is filled with a plastic compound to make the connection watertight. On the basis of official tests by the Danish Corrosion Center, a limit of 15 amp/anode (115 amp/sq m or 10.7 amp/sq ft) is recommended for maximum anode life. Magnetite anodes, suitable for application in soils, in fresh water, or in sea water, protect sheet steel piling in harbors, floating docks, municipal water towers, and a high-voltage d-c transmission cable laid in brackish water between the Swedish mainland and the Isle of Goetland.
