| Abstract: | The causes of corrosion in the circulating water system at Langfang plant have been studied by means of rotary coupon corrosion tests,linear polarization,water quality research,X-ray diffraction(XRD) and scanning electron microscope(SEM).The results demonstrated that the corrosion of steel carbon in the circulating water system was caused mainly by the electrochemical corrosion of dissolved oxygen in the water.The main reason of corrosion was that the added water in recycling circulating water systems was t... |
