摘要
某公司220万吨/年连续重整装置重整反应器进出口高温油气管道2017年定期检验时多处直管及弯头发生表面球化及微裂纹现象,为确定该批管道是否可以继续安全使用。在分析该批管道损伤模式的基础上,对损伤最严重的管道进行取样,分析了其金相组织、常温力学性能、高温力学性能、高温持久性能。
During the regular inspection of the high temperature oil and gas pipelines at the inlet and outlet of the reforming reactor of a 2.2 million ton continuous reforming unit of a company in 2017,the surface spheroidization and microcracks occurred on many straight pipes and elbows.In order to determine whether pipelines can continue to be used safely.Based on the analysis of the damage mode of pipelines,the most seriously damaged pipelines were sampled,and their metallographic structure,mechanical properties at room temperature,mechanical properties at high temperature and high temperature durability were analyzed.
