摘　　要：蒸汽是工业生产中常用的一种介质,其热量经常被用来进行各种生产活动。近几年蒸汽管道事故频繁发生,蒸汽管道的安全必须引起注意。TSG D7005—2018《压力管道定期检验规则——工业管道》中明确要求对某些情况进行应力分析,用以评估管道的安全性能。以某工厂蒸汽管道为例,利用CAESARⅡ软件对管道建立模型,计算管道各节点受力及位移情况,并用ASME B31.3-2016《工艺管道》进行校核,依据计算结果制定有针对性的检验方案,对工业管道的定期检验提供有效的数据支撑。Steam is a commonly used medium in industrial production,and its heat is often used for various production activities.In recent years,steam pipeline accidents have occurred frequently,and the safety of steam pipelines must be paid attention to.In TSG D7005—2018"Periodic inspection regulation for industrial pressure piping",stress analysis is explicitly required in some cases to evaluate the safety performance of pipelines.Taking a steam pipeline in a factory as an example,this paper uses CAESAR II software to establish a model for the pipeline,calculates the stress and displacement of each node of the pipeline,and checks it with ASME B31.3-2016"Process piping".Based on the calculation results,a targeted inspection scheme is formulated to provide effective data support for the periodic inspection of industrial pipelines.
