摘要
Φ1016油气管道是我国现有建成的大口径、高压、大排量、高强钢的主要干线管道,其安全隐患日益突出,尤其是环焊缝问题。本文作为国家“十三五”重点研发计划项目的研究成果之一,针对此类问题开展了三维漏磁/动磁检测方法研究,并在完成原型机实验及牵拉场测试基础上,开展了工业现场示范。该工业示范经过初步检测数据分析及开挖验证,验证结果符合实际工程需要。
Φ1016 oil and gas pipelines are the main trunk lines constructed and operated in China in recent years,with the feature of large diameter,high pressure,high flow rate and high-strength steel.The potential safety hazards of this pipeline are getting more and more prominent as well,especially the girth welds problems.As one of the research findings of"National Key Research and Development Project in the 13th Five-Year Plan",this paper discusses the method of 3D MFL/dynamic magnet in-line inspection tool,the sample machine of this type of inspection tool,how it performs during the pull-through test,and the subsequent on-site industrial demonstration.Based on the preliminary test data analysis and verification dig,the industrial demonstration practice turned out to be a conforming one as the inspection results have met the actual engineering needs.
