摘要
对开裂的条形浮阀塔盘的综合分析。结果表明 ,H2 S与HCl同时存在的电化学体系对 30 0系列不锈钢将会产生协同效应的严重腐蚀 ,引起腐蚀的主要杂质的是HCl,而H2
The cracked rectangular float valve tray has been analyzed and the result shows that H 2S and HCl existing in the electrochemistry system simultaneously have corroded 300 series stainless steel seriously. The corrosion was caused by HCl, and it was accelerated by H 2S.
