Abstract
Изобретение относится к области защиты металлов от коррозии в воде и может быть использовано для ингибирования коррозии в замкнутых системах стальных трубопроводов.Способ защиты стали от коррозии в воде состоит в совместном или последовательном введении в водную среду, контактирующую с поверхностями стали, аминогуанизона пировиноградной кислоты и фурацилина, соответственно в концентрациях 0,05...1,5 и 0,05...0,2 г/л.Технический результат состоит в значительном снижении коррозионных потерь и равномерном подавлении коррозии во времени.
