Abstract
Before being put to use, a new condenser of 600 MW unit was found corrosion leakage of a large number of 304L stainless steel tubes during the water leakage test. Through field investigation, sampling, chemical composition and mechanical properties test, metallographic analysis, corrosion area surface morphology and micro area component analysis, corrosion reasons were analyzed. The main reason for corrosion is improper installation. Stainless steel tubes were polluted by rain, soil, welding slag during the installation process. Carbon steel members cut the tubes when wore tubes, and was placed in such condition for a too long time. Moreover, the electric current occurred in repair welding with water may accelerate pitting holes.
