Detection process
The steel pipe advances in a straight line, and the multi-piece phased array probe is circled in the circumferential direction, and using electronic scanning to proceed the high-density sound beam incidence on the circumferential direction. A variety of focusing laws can be configured. Such as 0° longitudinal wave (partitionable) for core detection, and subsurface transverse wave detection (two-way).
Detection standard
GB/T 4162-2008《Ultrasonic testing method for forged steel bars》
GB/T8361-2008《Ultrasonic flaw detection method for cold drawn round steel surface》
System software（functional description and interface display）
Phased Array Bar 1
Phased Array Bar 2
1. The software automatically calibrates the quality of the chip
2. The software realizes angle compensation, which can effectively eliminate the problems caused by inconsistent sensitivity between chips
3.The software’s implementation of the TCG function can effectively solve the attenuation caused by excessive scope
4. After the sample pipe calibration is completed, the relevant parameters can be stored in the industrial computer for use when the same specification is tested next time.
The form of mechanical structure
The bar is conveyed in a straight line, and the probe rotates around the bar circumferentially for flaw detection.
Technical key points
Simple structure
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 service life.
Visualization
Phased array imaging inspection 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 seamless pipe and bar detection standards, reduce mechanical design requirements, reduce debugging time, and improve production efficiency.
More flexible
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.
