摘要
论述了基于局部椭圆变形的长输管道,在无法实施局部换管的特定条件下如何实施内检测工作的应用实践.通过对漏磁检测设备的连接臂、皮碗法兰和探头进行改造,提升了检测设备在3D(内径)弯管处的通过能力,实现了不发生卡球事故的安全目标.通过对现场实测数据和内检测报告数据的分析比对,验证了内检测数据量化精度达到Rosen公司标准.为今后在长输管道局部椭圆变形及其他变形的特定条件下,实施内检测工作积累了实践经验,为类似管道的内检测、技术管理和安全运营提供了一定的借鉴作用.
Abstract
The application practice of how to carry out internal inspection of long distance pipeline with local elliptic deformation under the specific condition that local pipe change cannot be carried out was discussed.Through the modification of the connecting arm,the cup flange and the probe of the magnetic flux leakage(MFL)testing equipment,the passing ability of the testing equipment at the 3D(inner diameter)bend were improved,and the safety goal of no stuck pigging accident was realized.Through the field measurement analysis and comparison of the internal detection data,it was verified that the quantization accuracy of the internal detection data reached the Rosen standard.The practical experience was accumulated for carrying out internal inspection work under the specific conditions of local elliptic deformation and other deformation of long-distance pipeline in the future,and provided a certain reference for the internal inspection,technical management and safe operation of similar pipelines.
