Abstract

The present invention falls into the field of systems for protection against the corrosion of the internal surfaces of boilers and similar apparatus. An electrode (11) runs across the entire length of a support (1). The watertight seal between the support (1) and a tank (15) is guaranteed by an O-ring (7). The sealing action against water between the support (1) and the rod (10) of the electrode (11) is achieved by at least one washer (9) positioned in the thickness of the body of the support (1). The support (1) is reversible and can be mounted either from inside or outside the tank to be protected.
