In an electrolyzer system having metallic supply and discharge piping subjected to shunt currents, the improvement which comprises a removable target electrode in the section of said piping subjected to said shunt currents, said target electrode having a lower overvoltage than the metallic piping being protected and comprising a valve metal having a ruthenium oxide coating.
In an electrolyzer system having metallic supply and discharge piping subjected to shunt currents, the improvement which comprises a target electrode frictionally held in the section of said piping subjected to said shunt currents, said target electrode comprising a removable member consisting of a metal substrate having a ruthenium oxide coating, whereby said target electrode reduces corrosion resulting from shunt currents.
In an electrolyzer system having metallic supply and discharge piping subjected to shunt currents, the improvement which comprises a cylindrically shaped removable target electrode frictionally held in the section of said piping subjected to said shunt currents and conductively attached to said piping, said target electrode having a conductive coating and a lower overvoltage than the metallic piping being protected.
