Role of Components Containing in Water on the Formation Corrosion - scale Deposits in Pipelines of Heating Systems

In this paper, we propose results of research on the establishment of presence of components in water of the southern cities of the Republic of Kazakhstan such as carbonate hardness, noncarbonate hardness and total hardness, content of free carbonic acid and impurities of different ions of iron (twoand three-valent), sulphate and chlorine ions, pH value. When the research course parameters of heat carrier (water): carbonate hardness, non-carbonate hardness, and the total hardness, content of free carbonic acid ions and HCO3 -, pH value, content of two and three valence iron ions, sulphate and chloride-ions in water were established, indicators of corrosion were calculatedby the value, which we concluded about the strength of corrosive effect on steel foundation of pipelines.
