FIELD: metallurgy.
SUBSTANCE: invention refers to protection of metals from corrosion and can be implemented in machine engineering at etching, in power and food industries for acid cleaning of equipment and also at acid washing of wells. Inhibitor contains, wt %: 5-nitrosalycylalsulphathiazole 29.0-23.3; 3-dodecylbenzimidazole iodide 9.6-19.5; polyethylene-polyamine 61.3-57.1.
EFFECT: upgraded efficiency of protecting steel, titanium and aluminium from corrosion and also increased inhibition of hydrogen pick-up.
