Abstract

The invention relates to the field of metal anticorrosion protection in water and can be used for inhibiting corrosion in closed steel pipeline systems.According to the invention, the use of α-ketoglutaric acid aminoguanizone is claimed as an inhibitor of steel corrosion in water, in a concentration of 0.05…1.00 g/l.
