Phased array ultrasonic automatic testing equipment for the seamless pipe (phased array testing system for small diameter seamless pipe)
It is applied to the automatic testing of high value-added medium and small diameter pipes and bars, to detect the longitudinal and transverse directions of the steel pipe except the blind zone; to detect the delamination defects of the steel pipe except the blind zone; to monitor the wall thickness of the steel pipe except the blind zone. Use electronic scanning to replace mechanical actions, reduce disturbance factors in the detection process, improve detection stability and accuracy, and fully replace various methods of conventional ultrasonic detection.
The steel pipe advances in a straight line, and multi-piece phased array probes are circled in the circumferential direction, using electronic scanning to proceed the high-density sound beam incidence on the circumferential direction. For various standards, multiple focusing laws can be configured.

1.The sensitivity of each channel is automatically calibrated through the software, so that the reflected wave of each channel for the same defect reaches a consistent height
2.Real-time C scan to achieve precise location of defects in two directions
3.S scan arranges all channels with the same function together by the color of the waveform, which is convenient for debugging and selecting the location with the highest reflected wave
4.Instantly display the quantity of genuine products and rejects on the screen of flaw detector.

Technical key points
Fully phased array technology for ultrasonic testing of seamless pipes and bars. The annular concave-array probe can cover the seamless pipes and bars with full circumferential sound beams. The use of electronic sound beam rotation instead of mechanical sound beam rotation can greatly improve system stability and equipment life.
Phased array imaging detection can have B scan, D scan, S scan and C scan at the same time, and can build three-dimensional graphics and display defect images through modeling.
Easy to operate
Cooperating with electronic angle deflection, the angle is adjusted by software, and it is easy to change specifications and debug, fully meet the detection standards of seamless pipe and bar, reduce mechanical design requirements, reduce debugging time, and improve production efficiency.
The phased array can perform dynamic focusing of the sound beam, the focus depth is continuously adjustable, flexible and convenient, and the sensitivity and resolution are greatly improved.
