摘要
本文通过对烷基化装置中蒙乃尔材料失效实例分析发现：构件的失效方式有腐蚀失效、机械失效两种。并对现场修复工艺进行了探讨，认为根据不同的使用条件和要求采用不同的焊接材料、工艺规范参数、焊后处理手段，严格清理和保护，能获得较为理想的修复质量。并列举了烷基化装置常见失效修复的实例，对实际修复工作和蒙乃尔材料的焊接都有重要的指导意义。
Through the analyses of failure cases of wionel in alkylation devices, it is discovered in this paper that there are two kinds of failure patterns of Monel, which are corrosion failure and mechanical one. For various service conditions and requirements, satisfication repairing qualities can be gained by using corresponding welding materials, welding parameters, post weld treatment methods and strict clean and protection processes. Several repairing cases for Monel failures in alkylation devices were given out and they are useful to both repairing and welding of Monel.
