Beschreibung
Zusammenfassung:	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.4 cl, 2 tbl Изобретение относится к защите металлов от коррозии, а именно, к ингибиторам коррозии для гидроиспытаний оборудования. Ингибитор коррозии состоит, мас.%: азотсодержащее основание 10-30, гетероциклическое азотсодержащее соединение 20-40 и соль ароматической карбоновой кислоты 30-65. Изобретение повышает эффективность защиты от коррозии для гидроиспытаний оборудования из черных и цветных металлов при продолжительном времени. 3 з.п. ф-лы, 2 табл.
