摘要: 分析表明炼油厂催化裂化装置再生器取热盘管失效的主要原因是腐蚀疲劳。本文就该实际工程条件下,对1Cr18Ni9Ti及1Cr25Ni20两类奥氏体不锈钢在高温含微量氯离子水中的腐蚀疲劳现象及成因进行了讨论。改善汽水流动条件可显著延长盘管的使用寿命。
Abstract:Heat coils made of austenitic stainless steels were installed in fluidized bed of an actifier of catalytic cracker installation in an oil refinery unit. Steam—water mixture circulated within the coils with high pressure. Corrosion fatigue failure occurred in the coils in about 40 days after commissioning of the unit. In the present paper, corrosion fatigue phenomenon of austenitic stainless steels in high temperature,high pressure water was discussed in the real engineering condition. It was indicated that the lifetime of the coils could be largely increased by improving the steamwater flow condition.
