Abstract
Изобретение относится к области защиты металлов от коррозии в воде и может быть использовано для ингибирования коррозии в замкнутых системах стальных трубопроводов.Согласно изобретению, способ защиты стали от коррозии в воде состоит в раздельном или совместном введении в водную среду, контактирующую со стальными поверхностями, адипиновой кислоты и α-кетоглутаровой кислоты, соответственно в концентрациях 0,025…0,75 г/л и 0,05…0,75 г/л.Технический результат изобретения состоит в снижении скорости коррозии до 40 раз.
