裂解汽油加氢反应器泡罩开裂原因分析

摘要

根据腐蚀检查情况,从材料、工艺、腐蚀机理等方面综合考虑,对泡罩进行了失效分析,包括开裂泡罩和未开裂泡罩的宏观检查,开裂泡罩的材质组成分析、材料金相组织检测、铁素体含量检测以及扫描电镜观察等,最后给出了防止泡罩开裂的建议和措施.%Though visual inspection,material composition test,fracture microstructure analysis,ferrite content detection,micro hardness test,fracture morphology analysis in SEM,etc.,the failure cause of the bubble cap cracking in hydrogenation unit reactor was discussed,and the advice of preventing the cracking in bubble cap was put forward.
