催化裂化装置烟道管件故障失效分析

Failure Analysis of Catalytic Cracking Unit Flue Pipe

催化裂化装置的烟气管线工作温度高,烟气组分又比较复杂,这就造成了烟气管线管件失效形式是多种多样的。通过解决历年来生产中出现多次故障失效问题,分析是应力腐蚀与管件受限造成了失效,并针对性提出今后改进措施与建议。

FCC unit flue gas pipeline high working temperature, gas composition and more complex, created a flue gas line pipe failure form, was varied. By addressing the fault failure occurred more than once over the years, analysis was limited stress corrosion and fittings caused by the failure, and the measures and suggestions for future improvements were puts forward.
