METHOD OF ANODIC GROUNDING OF METALLIC TANK Russian patent published in 2011 - IPC C23F13/00 

FIELD: electricity.

SUBSTANCE: method involves drilling of horizontal inclined well the inlet and outlet of which is located beyond berm of the tank or tanks, assembly of protective cartridge of tubes, assembly of electrodes of anodic grounding to garland or garlands with calculation of location of each of them under separate tank, pulling of garland or garlands to protective cartridge, pulling of assembled cartridge in the well; at that, on both ends of protective cartridge polymer connection pipes are led out to ground surface; space between connection pipe and cartridge is plugged; cable lines are taken out to instrumentation station to which cable line is supplied from "+" terminal of station of cathodic protection, and to housing of each tank there connected is cable line from "-" terminal of station of cathodic protection; at that, first, protective cartridge is used as electrode of anodic grounding, and then, as it is dissolved, electrodes of anodic grounding are connected.
