Magnetic flux leakage inspection function: detecting internal

and external surface defects of steel pipes.

Compliance with standards: API Standard of American Petroleum Institute

Technical features:

1. The steel pipe advances in a straight line and the transverse defects adopt the passing type and the longitudinal defects adopt the rotary type;

2. The magnetic flux leakage detection system has the functions of automatically recording, counting, querying and analyzing the detection results;

3. DSP signal digitization processing technology, to solve the independent processing of each channel signal, the transmitted signal to noise ratio is high.

4. Ensure that the vertical rotation detection mechanism of the equipment runs reliably all year round, eliminating the problem of spark interference and contact wear.

5. Solve the contradiction between the tangent point of the steel tube arc surface and the non-replacement plane probe on the algorithm.

6. Accurate differentiation of internal injury and outer injury by the detection chart.

7. The ability to detect cracks, inclusions, folds, blowholes, pits and other defects with high sensitivity.

8. Each channel parameter can be adjusted independently;

9. The equipment can be a reliable and stable operation all year round, good repeatability;

10. Automatic charging, automatic detection, automatic sorting, automatic defect identification.
