| Abstract: | A portable magnetic flux leakage testing device for field inspection of the pipelines in use has been developed by combining computer, electromechanical control, signal processing and magnetic flux leakage testing. Experimental data show that the device is of high sensitivity, high efficiency and low cost. The defects in both the inside and outside walls of a pipeline can be detected out by scanning only once from the outside and it has wide application prospects in the fields of metallurgy, petrochemical industry, water supply and city warming facilities. |
