Synergistic Effect of Tubing Defects and Microbes on Corrosion of Stainless Steel Pipes in Condenser

Combining the distribution regularity and morphological features of waterside corrosion parts on stainless steel tubes of the condenser in a power plant, the sediments on the corrosion parts and tubing components near corrosion holes of inwall were analyzed by chemical analysis, SEM and EDS. The results showed that tubing defects and microbes had synergistic effect on the formation of pitting corrosion. Some preventive measures were proposed to ensure the stainless steel condenser running stably.
