Method for inhibiting corrosion in cooling systems and compositions therefor, containing a nitrite corrosion inhibitor and bromosulfamate

摘要: The method of adding to a nitrite corrosion inhibitor composition an effective amount bromosulfamate which is stable with respect the and provides biocide, bactericide fungicide. using this component utilized at about 0.1 10 ppm (residual) optimum 0.2 bromosulfamate. comprises reacting together sodium bromide (NaBr), hypochlorite (NaOCl) or chlorine, sulfamate (NaSO3 NH2) sulfamic acid, product "fresh" in treating solution.
