Offline Ultrasonic UT Testing equipment is suitable for automatic detection of various tubes and bar defects testing. The principle of ultrasonic flaw detection is that the ultrasonic wave enters the tube rod after water coupling, and the incident wave propagates. When there is a defect in the tube,the ultrasonic reflection will be caused. The ultrasonic instrument will report the ultrasonic reflected signals to the real-time alarm after the amplified signal processing, and realize the automatic detection of the defect.

Wireless Transmission Pipe Ultrasonic Flaw Detector Introduction
Rotating probe configuration
1. Probe configuration on the spindle section 1
A total of 3 probe adjustment frames are placed on section 1 at 120°apart. Each of the adjustment frames is equipped with a 2-channel combined ultrasonic line focusing longitudinal probe to detect longitudinal defects of the steel tube in a clockwise direction.
Detection of defects: Vertical and vertical defects in the steel pipe are detected in a clockwise direction.
Center frequency: 5.0MHz±10%
Coupling method: water immersion method
Quantity: 3 sets of probes, each consisting of 2 wafers. These 3 sets of probes are evenly distributed in the circumferential direction of the workpiece, spaced 120° apart, on the same section. A total of 6 channels of water immersion probes.
2.Probe configuration on the main shaft section2
A total 3 probe adjustment frames are placed on section2, separated by120°, and a 2-channel combined ultrasonic line focusing longitudinal probe is arranged on each adjustment frame to detect longitudinal defects of the steel pipe counterclockwise.
Detection of defects: counter-clockwise detection of longitudinal defects inside and outside the steel pipe.
the center frequency: 5.0MHz ± 10%
coupling method: water immersion method
Quantity: 3 sets of probes, each consisting of 2 wafers. These 2 sets of probes are evenly distributed in the circumferential direction of the workpiece, spaced 120° apart, on the same section. A total of 6 channels of water immersion probes.
