CORROSION OF CARBON STEEL ST3 UNDER EXPLOITATION OF HYDROTECHNICAL UTILITIES BUILTS ON THE KURA AND ARAS RIVERS

Abstract

There was studied a corrosion of carbon steel St 3 under field conditions of the exploitation of hydrotechnical utilities on the Kura and Aras rivers. Afterlong-term (12 months) experiments we obtained the data confirming that steel corrosion in waters of these rivers occurs by electrochemical mechanism and has cyclic character, that is to say depending on the seasons either increases or
decreases. Maximum rate of corrosion under atmospheric conditionsis observed in winter. Such dependence is also observed in aqueous sphere.
