摘要
管道是工业生产的命脉,由于管道长期承受温度、压力、载荷的影响而容易发生各种失效。管道的敷设方式包含架空以及埋地两种,管道的应力分析评价属于管道定期检验安全评估中的一项重要工作,由于这两种敷设方式管道的受力条件具有明显不同,因此必须对埋地管道和架空管道的标准适用性进行详细的研究。通过利用CAESARⅡ软件建立模型,并采用ASME B31.3-2014《工艺管道》和ASME B31.4-2016《液态烃和其他液体管线输送系统》分别对架空管道和埋地管道进行校核,计算管道的整体应力水平,为工业管道的定期检验提供有力的技术支撑。
Pipeline is the lifeblood of industrial production.Due to the long-term influence of temperature,pressure and load on the pipeline,various failures are prone to occur.Pipeline laying methods include overhead and buried.Pipeline stress analysis and evaluation is an important work in the safety assessment of pipeline periodic inspection.Because the stress conditions of the two laying methods are obviously different,the standard applicability of buried and overhead pipelines must be studied in detail.In this paper,CAESAR Ⅱ software is used to establish the model,ASME B31.3-2014 "Process Piping" is used to check the overhead pipeline,and ASME B31.4-2016 "Pipeline Transportation Systems for Liquids and Slurries" is used to check the buried pipeline respectively.The overall stress level of the pipeline is calculated,which provides strong technical support for the periodic inspection of industrial pipelines.
