基于三轴漏磁内检测技术的管道特征识别

摘要

漏磁内检测器最早用来探测由于腐蚀导致的金属损失.随着内检测器设计、传感器和电子技术的进步,漏磁内检测器的探测、识别能力显著提高,可以识别、有时甚至可以确定多种类型的管道缺陷和特征的尺寸.简要介绍了漏磁内检测的原理,分析了目前工业上使用的最先进的高分辨率三轴漏磁内检测器的特征,重点探讨了如何使用三轴漏磁内检测数据识别管道异常特征和管道结构特征.%Magnetic Flux Leakage( MFL) in-line inspection tools was developed to detect metal loss resulted from corrosion in the early days.With the development of tool design, sensors, and electronics, MFL tools can identify and sometimes size many types of pipeline defects and features.This paper briefly introduced the principle of MFL in-line inspection, then analyzed the advantages of advanced high-resolution axial magnetizing MFL tools with Tri-Axial sensor technology, and discussed how to identify pipeline anomalies and pipeline structure features using the Tri-Axial MFL data.
