Special features of the influence of corrosive elements on the localization of the processes of destroying the metal with the pipe laying in the soil

Abstract

In the article the basic forms of the corrosive elements of those functioning on the underground metallic conduits are examined and their influence on the degree of localization of the electrochemical corrosion of metal is revealed. It is established that as a result interaction of the macros-pair of those located outside and inside the conduit is possible the intensification “external” corrosion of conduit due to “the internal” and directly opposite phenomenon.
