| Abstract: | The fundamental principle and purpose of nondestructive testing by magnetic flux leakage (MFL) applied to the pipeline erosion detection is introduced. The collective project, system composition and working procession of pipeline detection equipment are stated in detail. The hardware design is analyzed. The large inspection data are collected by database. This paper describes the factors disturbing the MFL signal, and presents the methods of eliminating the interferential factors by filter and digital smooth. The interpolation of radial basis function is used to compensate MFL signals and describes the pipe detection. The estimation model and method of detection parameters are presented. Detection inspection and signal processing are intelligent and effective in practice. |
