摘要：
The experimental results on purifying of cupronickel condenser tubes by means of porous rubber pellets impregnated by ferrosulfate have been discussed. The conditions of forming the protective anticorrosion film on these tubes at their purifying by porous rubber pellets and the dosage of ferrosulfate into a cooling water have been studied. The content of iron in a cooling water has been defined before and in the period of the inhibitor intake. The analysis of the composition of precipitations on tubes has been carried out. The process of making the reliable protective film on working tubes has been worked out by means of the periodical passage of porous pellets impregnated by the inhibitor solution with the concentration Fe=2.5 g/l and pH=2.
