Abstract: This work has been executed within the complex program of the NAN of Ukraine “Problems of a resource and safety of operation, structures, buildings and machines (RESURS)”. The urgency of the subject-matter is conditioned by a lot of equipment and apparatuses which has been long used in oil-refining and chemical industries under a corrosive medium. A large part of this equipment has its scheduled resource exhausted or is about to it. The purpose of this research was to find out ways to estimate degrees of steels 09G2S and 20 degradation after a continuous service at oil-refining and chemical enterprises. The task of the work is determination of electrochemical descriptions sensitive to degradation changes of a metal and tendencies in their change. While researching there were used standard methods which are used at electrochemical and metalоgraphic experiments.

Keywords: electrochemical corrosion, degrade steel, initial steel, potential of corrosion, metallography, chloride sodium.

Pages: 115-122.
