Conference on Corrosion and Cavitation Protection of Hydropower-plant Structures and Equipment

Abstract

The first All-Union Scientific-Engineering Conference on Corrosion and Cavitation Protection of Hydropower-PLant Structures and Equipment was held in Leningrad in October. 1974. Nearly 250 delegates from 88 organizations participated, including representatives from many hydroelectric power star/ons and research organizations. Over 70 papers and communications were presented at the plenary sessions a~d at the meetings of three sections. After an introductory address by M. F. Sldadnev. Director of the B. E. Vedeneev All-Union Scientific-P.esearch Institute of Hydraulic Engineering (VNIIG) at the plenary session, the following papers were presented: The outlook in hydraulic engineering construction and problems in corrosion and cavitation protection, by L. I. Kudoyarov, Main Directorate of the Scientific-Research and Design Institute (Glavniiproekt), and Yu. U. ~del' (VNIIG)~ scientificproblems in corrosion and cavitation protection, by Ya. IVL Kolotyrkin and Go NL Florianovich, L. Ya. Karpov Physicochemical Institute, N. P. Rozanov, Magnitogorsk Mining and Ivletallurgical Institute (MGMI). and YUo Uo ~del'; and anti-corrosion measures under operational conditions and during flac design of components, by A. F. Dmirrukl-Rn. State Trust for Organization and Rationalization of Regional Electric Power PLants and Networks (ORGRI~S), E. P. Shtern, Leningrad Directorate of the Power Economy (Lsndnergo), and M. N. Fedorov, Special Design Bureau of the Moscow State Institute of Steel Construction for Hydraulic Structures (SKB Mosgidtrostal,). At the concluding plenary session, G. O. I~vit (VNllG) presented a paper on methods for determining an engineering-economic basis for protective measures. The proceedings of the section on corrosion and electrochemical protection were chaired by V. V. Krasnoyarskii Institute of Physical Chemistry (I FKh) of the Academy of Sciences of the USSR. Questions on the prediction of corrosion of iron in fresh waters were discussed by V. M. Kadek, Z.. F. Oshis and D. V. VitoLa, the G. Plekhanov Institute of Inorganic Chemistry (INKh) of the Academy of Sciences of the Latvian SSR, Yu. N. Noginov (VNllG), V. V. Kuznetsov, and L. V. Verzhbitskaya, Penn University. A paper was presented by T. I. Malyshev (VNIIG)which summarized the work during 1967-74 on the preliminary classification of the fresh waters in the USSR and their aggressive attack on carbon steels. An important, and in many cases also a determining, role in the development of corrosion in fresh waters is played by micro-organisms. The paper by M. A. Luchina (VNIIG), Yu. N. Norokh, and G. N. Emers, Dnepropetrovsk University. demonstrated the rising scientific level of investigations into microbiological corrosion, and the broad range of full-scale items investigated.The surfaces of metalwork used in the equipment at hydropower plants are subjected, as a rule. to pitting corrosion, and a paper devoted to a study of its mechanism in fresh waters was presented by V. V. Kuznetsov, L.V.Verzhbitskaya, G. V. Hakleev, and V. F. Knyazeva, Perm Uni...
