Piping internal electrolytic corrosion protection system - uses removable anode rod inserted at angle into piping corrosion

摘要

The protection device prevents electrolytic internal corrosion in sections of piping carrying aq. liquids that are not cathodically protected and that are connected by an insulating connection to a pipe section that has cathodic external protection. A rod-shaped anode is in the region of the insulating connection and a voltage is applied to it that is more positive than the inner potential of the externally-unprotected piping section. Specifically the anode is fixed into an anode support made of nonconducting material which can move with the help of a spindle in a tubular support at an angle to the main pipe which has at least two guides. The tubular support is connected via a flange to a reducing piece.
