FIELD: chemical compositions.
SUBSTANCE: invention relates to compositions of chemical agents for inhibiting corrosion and scale formation and can be used, in particular, in hot water pipe systems of thermal power plants. The inhibitor contains the following components in wt.%: sodium polymethacrylate 3-7; aminosulfonic acid 9-15; sodium metaphosphate 1.0-1.5; disodium metasilicate 0.03-0.1; the rest is water.
EFFECT: creation of a multifunctional corrosion inhibitor with combinations of components that provide effective corrosion inhibition of carbon steel, as well as the prevention of scale formation.
