Abstract

Pipeline is the main way of oil and gas transportation; however, pipelines easily produce internal corrosion under the laying environment, transmission medium, and other factors and even lead to an explosion accident. The cause and process inversion of pipeline explosions is important in the failure analysis of oil and gas pipelines. This study examines the impact of explosions on the physicochemical properties of steel pipelines, focusing on the general mechanisms of pipeline failure in oil and gas transportation. Based on a case study of a pipeline burst caused by corrosion in a mountainous area, the influence of the law of shock load on the physical and chemical properties of pipelines is analyzed. The physicochemical properties of the residual samples are tested and analyzed to validate the failure analysis results. Finite element simulation is employed to reproduce the pipeline burst failure process, and the results are consistent with the field data. The findings provide insights into the failure mechanisms of oil and gas pipelines, offering guidance for the safe operation and maintenance of such pipelines in various environments.

爆炸对钢管管道理化性能影响机理分析

管道是油气运输的主要方式；然而，管道在敷设环境、输送介质等因素的作用下，容易产生内部腐蚀，甚至导致爆炸事故。管道爆炸的原因和过程反演是油气管道失效分析的重要内容。本研究考察了爆炸对钢管管道物理化学性能的影响，重点研究了油气运输中管道失效的一般机制。以某山区管道腐蚀爆震为例，分析了冲击载荷变化规律对管道理化性能的影响。对残余试样的物理化学性质进行了测试和分析，以验证失效分析的结果。采用有限元模拟方法再现了管道爆破破坏过程，结果与现场数据吻合较好。研究结果对油气管道失效机理有深入的认识，为各种环境下油气管道的安全运行和维护提供指导。
