FIELD: corrosion protection.
SUBSTANCE: invention relates to the protection of metals from corrosion, namely, to corrosion inhibitors for hydraulic testing of equipment. The corrosion inhibitor consists of, wt. %: a nitrogen-containing base 10-30, a heterocyclic nitrogen-containing compound 20-40 and an aromatic carboxylic acid salt 30-65.
EFFECT: invention increases the effectiveness of corrosion protection for hydro-testing of equipment made of ferrous and non-ferrous metals for a long time.
