Rod Tube Rotary Eddy Current Flaw Detector ET 15406590 Performance 


Testing Standard:GB/T 11260-2008 round steel eddy current testing method, GB/T 7735-2004 steel tube eddy  

Current testing method 

Longitudinal artificial injury:0.10(depth)×0.10(width)×20mm(length)

Tube end conditions:


  • deburring at both ends, cross-sectional deformation equal to less than the diameter tolerance 

  • Straightness tolerance: tangential direction up to 1.5mm/m and not exceeding the total length of the workpiece 

  • Diameter tolerance and ovality: reference DIN standard 


Rotating flaw detection system technical performance index


(1)The eddy current flaw detector can accurately, reliably and stably record, alarm and mark the defects of the finished steel pipe.

(2)Detection speed:<60m/min

(3)Detection of end -end tail dead zone:

    50mm signal to noise ratio: ≥ 10dB

    Sample miss rate: 0%

    Sample stick false positive rate: ≤2%

    Stability: ≤1dB after 2 hours

    Marking accuracy: ±30mm

    Poor circumferential sensitivity: ≤1dB

(4)100% coverage detection, the instrument sets the upper and lower boundaries, exceeding or lower than the automatic alarm record;

(5)Flaw detection machine operation mode: fully automatic, complete electronic control system, testing equipment, auxiliary control.


The high-speed rotation detection system has the following important features:


  • Precision positioning and drive mechanism technology in tube rod inspection;

  • Adopting the rotation of the probe and straight forward of the tube rod, the speed is fast, the noise is small, reliable, and the sensitivity is high;

  • Multi-channel noise suppression technology;

  • Detecting steel rods of different diameters without changing the probe, can continuously and accurately adjust the gap between the steel rod and the eddy current probe;

  • The signal adopts high-speed DSP signal processing mode, and each channel signal is processed independently, and the transmitted signal-to-noise ratio is high;

  • Wireless transmission technology, no sparks:

  • Has a high service life and a small longitude detection blind zone;

  • Do not replace the probe rotation detection technology;

  • The equipment can operate stably all year-round.
