Investigation of processes occurring at cathodically protectedunderground installations: Experimental study of pH alteration and mathematical modeling of oxygen transport in soil
Original language description
A detailed analysis of the complex processes occurring at the surface of cathodically protected under-ground metal installations is presented. In the first part an alteration of soil pH in vicinity of cathodicallypolarized buried specimen of carbon-steel pipe is investigated experimentally. In the second part a sta-tionary two-phase oxygen transport to a defect in the protective coating of an underground pipe is studiedby mathematical modeling and protection current solely given by oxygen reduction are calculated. Thisinformation is crucial to an evaluation of subsequent processes taking place at a protected metal surface,which is part of a follow-up study.
