ABSTRACT
Corrosion behavior of the Cu pipe system has been investigated by long term experiment. The two identical experimental systems were made and fulfilled by the solution of 3 % NaCl. The work medium in the first system was flowing eight hour in day and in the second the medium was stagnant. The systems were subjected eight hour in day to temperature of 80°C. After eleven month the experiment was finished and the corrosion attack and character of corrosion products in the systems have been investigated by light and SEM microscopy, EIS tests and visually too.
