MATERIALS OF THE XVI INTERNATIONAL SCIENTIFIC AND PRACTICAL CONFERENCE ★ March 30 - April 7, 2020
TECHNICAL SCIENCE
CORROSION RESISTANCE OF STRUCTURAL MATERIALS IN
RECYCLED WATER

Abstract. The article is devoted to the issues of corrosion control in recycled 
systems operating on high - salinity water. Attention is paid to the corrosion resistance 
of structural materials, in particular, ferrous metals used in recycling water supply 
systems. The main factors that affect the rate of corrosion and the conditions that 
determine the corrosion of equipment of circulating systems are given. The special 
influence of carbonate deposits and microorganisms, as well as the influence of 
temperature, flow rate and chemical composition on electrochemical corrosion was 
noted.
Keywords. Corrosion, corrosion resistance, structural material, recycled water, 
carbonate deposits, electrochemical corrosion, microbiological corrosion.
Much attention is paid to the issues of corrosion resistance of structural 
materials in recycled cooling water both in domestic [1] and in foreign literature [3].
The main structural materials of recycled water supply systems are ferrous 
metals. Individual parts of the equipment (shut-off equipment, pumps, heat exchangers, 
etc.) are made of alloys based on non-ferrous metals: brass, bronze, titanium. This 
explains the interest in the corrosive behavior of ferrous metals in circulating systems. 
It should be said that this process is extremely complex, depending on a large number 
of variables and their interactions [2]. The main factors influencing the corrosion rate 
of metals in recycling water, are its chemical composition, salinity, amount of 
dissolved gases, temperature, pH, fluid velocity, surface condition of the metal. 
However, as G. V. Akimov notes, the corrosive aggressiveness of water probably also 
depends on many unaccountable factors, including the presence of impurities in the 
water that are not determined by conventional chemical analysis.
