Abstract
Изобретение относится к защите 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 во введении в коррозионную среду 50-150 мг/л бороглюконата кальция и 50-150 мг/л пирофосфата натрия.Технический результат изобретения состоит в снижении скорости коррозии стали в воде.
