含体积型缺陷管道的剩余强度评价
|
摘要
由于管道输送介质易燃、易爆等特点,管道一旦失效,发生泄漏,输送介质将迅速扩散,遇到火源就会剧烈燃烧,甚至爆炸,其后果是灾难性的。为了防止管道意外事故的发生,采取适当的方法对含体积型缺陷管道的剩余强度作出评价。基于含体积型缺陷管道的受力情况,应用ABAQUS有限元分析软件模拟缺陷管道的力学行为,计算含体积型缺陷管道的失效压力,分析缺陷长度、缺陷深度以及缺陷宽度与失效压力的关系,得出管道允许存在的最大缺陷尺寸。依据该尺寸对含体积型缺陷管道作出继续使用、降压、修复、更换等方案选择,以此保证油气管道的输送安全。
Due to pipelines' medium of transportation is flammable and explosive,or its other characteristics,once the pipeline exist failure,leakage occurs,the rapid diffusion transport medium,encountered the fire will be intense burning,or even an explosion,the consequences are disastrous.In order to prevent the pipeline accidents,adopt appropriate methods to assess the residual strength of the pipe with volumetric type flaw.The force of the pipe with volumetric type flaw based on mechanical behavior,finite element analysis software ABAQUS was applied to simulate defects in pipes,calculating the failure pressure body containing product defect analysis of pipeline,defect length,defect depth and defect width and failure pressure,the maximum allowable flaw size of pipe.According to the size of the pipe with volumetric type flaw to continue to use,buck,repair,replacement scheme selection,in order to ensure the safe transportation of oil and gas pipeline.
