摘　　要：长输油气管道一般均采用埋地敷设,敷设在地下的管道容易因受到第三方破坏、腐蚀,以及一些不利地质条件的影响而产生破坏。当管道通过天然或者人工障碍物时一般采用穿越方式,穿越管道受力复杂,一旦发生泄漏爆炸,危害极大。利用CAESARⅡ软件对穿越管道进行应力分析,并用ASME B31.4-2016进行校核,计算管道的应力水平,为管道的定期检验提供有力的数据支撑,同时改进现有外防腐层检测仪器,对管道的防腐层进行检测,保证管道的安全。Long-distance oil and gas pipelines are generally laid underground,which is vulnerable to third-party damage,corrosion,and some adverse geological conditions.When the pipeline passes through natural or artificial obstacles,the crossing mode is generally adopted,and the force of crossing pipeline is complex.Once a leakage and explosion accident occurs,it will cause great harm.In this paper,CAESAR II software is used to carry out stress analysis through pipelines,and ASME B31.4-2016 is used to check the stress level of pipelines,which provides strong data support for regular inspection of pipelines.At the same time,the existing external anti-corrosion layer detection instruments are improved to detect the anti-corrosion layer of pipelines and ensure the safety of pipelines.
