摘要

在石油石化行业中存在大量需要进行保温的管道/设备设施。但是，在实际运行过程中，这些保温结构可能会出现不少问题，导致保温结构失效、保温层下腐蚀，给生产带来了安全隐患。总结了石油石化行业中造成保温结构失效的原因、保温结构失效的评价方法和保温结构寿命评估技术。同时也总结了目前应用于石油石化行业中保温层下腐蚀的检测技术，以及对保温层下腐蚀防护的一些方法，希望对解决石油石化行业保温层下腐蚀提供一定的参考。

Abstract

There are a large number of pipelines/equipment and facilities need to be thermally insulated in the petroleum and petrochemical industry. However, in the practical operation, many problems may appear in the thermal insulation structures, such as thermal insulation structure failure and corrosion under the thermal insulation which could bring safety risks to the production. In this work, the causes and evaluation methods of thermal insulation structure failure as well as the life evaluation mehtods of thermal insulation structure in the above - mentioned industry were summarized. Meanwhile, the detection method of corrosion under the thermal insulation layer in such industry as well as some corresponding anticorrosion methods were reviewed, with the expectation of providing certain guidance for solving the corrosion problem under the thermal insulation layer in the petroleum and petrochemical industry.

Key words： thermal insulation structure failure; corrosion under thermal insulation layer; petroleum and petrochemical industry; detection technology; corrosion and protection
