摘 要:管道在油气运输中占有重要作用,随着管道服役年限的增长,管道易产生各种形式的缺陷。结合现场工况,采用ANSYS仿真软件建立无损天然气管道和含内腐蚀条形缺陷管道,通过对比压力校核和应力校核条件,验证仿真模型的准确性。建立的线性回归模型对不同内压下的缺陷管道最大应力值进行回归分析。随后针对缺陷管道提出一种智慧套筒修复技术,建立缺陷管道套筒修复模型,研究不同环氧层厚度对管道缺陷处补强效果的影响,确定了最优的环氧层厚度,并进行了实验和现场验证。通过智慧套筒监测系统对管道缺陷处进行了实时应变监测,基于采集到的实时应变数据证实了管道缺陷补强的有效性,为管道缺陷修复及修复后的效果评价提供了切实可行的应用方法。Pipeline plays an important role in oil and gas transportation.With the increase of service life of pipeline,it is easy to produce various forms of defects.Combined with the field conditions,ANSYS simulation software was used to built a non-destructive natural gas pipeline and a pipeline with internal corrosion defects.By compared the pressure check and stress check conditions,the accuracy of the simulation model was verified.The linear regression model was established to analyze the maximum stress value of the defective pipe under different internal pressure.Subsequently,a smart sleeve repair technology was proposed for the defective pipeline,and a sleeve repair model was established for the defective pipeline.The influence of different epoxy layer thickness on the reinforcing effect of the defective pipeline was studied,the optimal epoxy layer thickness was determined,and experiments and field verification were carried out.The smart sleeve monitoring system was used for real-time strain monitoring of pipeline defects.Based on the collected real-time strain data,the effectiveness of pipeline defect reinforcement was confirmed,which provided a practical application method for the repair of pipeline defects and the evaluation of the effect after repair.
