Magnetic leakage testing for short-circuit small diameter pipes

  • 摘要: 建立了小径管缺陷漏磁检测的三维有限元模型,得到缺陷漏磁场的空间分布特性。通过改变缺陷的深度和宽度,研究了腐蚀缺陷对漏磁检测信号的影响,研发了短接小径管的漏磁检测装置,在规格(外径×壁厚)为φ27 mm×3.5 mm小径管内壁加工了人工腐蚀坑缺陷,并对模拟缺陷进行检测。结果表明:漏磁检测技术可以实现短接小径管腐蚀缺陷的快速扫描检测。
    Abstract: In this paper, the magnetic flux leakage detection technology is used to study the short-circuit small-diameter tube detection technology. A three-dimensional finite element model of small-diameter tube defect magnetic flux leakage detection is established, and the spatial distribution characteristics of the leakage magnetic field are obtained. By changing the influencing factors such as depth and width of defects, the influence of corrosion defect parameters on the leakage magnetic field signal is studied, and the spatial distribution characteristics of the leakage magnetic field are found. A short-circuit small-diameter tube magnetic flux leakage detecting device was developed, and the inner diameter of the small-diameter tube with a size of φ27 mm×3.5 mm was artificially simulated and the test was performed. The experimental results show that the magnetic flux leakage detection technology can realize the detection of short-circuit small diameter pipes.
