Beschreibung
Zusammenfassung:	The invention relates to the protection of metals against corrosion in water and can be used to inhibit corrosion in closed steel pipeline systems.According to the invention, the use of sodium pyruvate as an inhibitor of steel corrosion in water, at a concentration of 0.05...1.00 g/l is claimed. Invenţia se referă la domeniul protecţiei anticorozive a metalelor în apă şi poate fi utilizată pentru inhibarea coroziunii în sistemele de conducte închise din oţel.Conform invenţiei, se revendică aplicarea piruvatului de sodiu în calitate de inhibitor de coroziune a oţelului în apă, la o concentraţie de 0,05...1,00 g/l. Изобретение относится к области защиты металлов от коррозии в воде и может быть использовано для ингибирования коррозии в замкнутых системах стальных трубопроводов.Согласно изобретению, заявляется применение пирувата натрия в качестве ингибитора коррозии стали в воде при концентрации 0,05...1,00 г/л.
