FIELD: metallurgy.
SUBSTANCE: invention relates to compositions for corrosion inhibition and scales in heat-exchange equipment of low-carbon steel. Water-soluble corrosion inhibitor of metals contains, wt %: sodium tripolyphosphate 10.0-20.0; ethanolamine borate 80.0-90.0.
EFFECT: protection effectiveness increase against corrosion and scale, and also for protection against mechano-chemical wear of heat-exchange equipment made of ferrous metals.
