Cathodic Protection Wells Service
The cathodic protection is a technique to prevent electrochemical corrosion that is applied to metal structures in contact with environments with electrical conductivity. Consists essentially in making circular current between an electrode, the anode, and the surface of the structure to be protected, said cathode. This lowers the current electrical potential of the metal surface, to break up the corrosion.
The technique of cathodic protection officially borned in England in 1824, states in America a century later, and finally throughout the world since the 1960's, 1970.
In Italy, the cathodic protection was applied initially to protect the lead sheathing of telephone cables, around 1930, and to protect oil pipelines, gas pipelines, aqueducts and structures susceptible to corrosion.
Well deep Cathodic
Ital Sonda over the years has performed countless working on the formation of such dispersori by creating vertical drilling depth usually included between 80 and 120 meters and a diameter of between 13 and 20 centimeters from the insertion of the armature and the anode backfill all 'inside of the shaft, leaving a space of at least 40 meters between the top of dispersore and the soil surface.
The realization of deep wells into the implementation needs to offer many advantages, in particular the need for spaces, better distribution of current protection, lower electrical interference.
