Wireless Transmission Pipe Ultrasonic Flaw Detector

The ultrasonic pipe testing equipmentsystem is suitable for the automatic detection of various internal and external defects of steel pipes. The principle of ultrasonic flaw detection is that after the ultrasonic wave is coupled into the steel pipe through water, the incident propagation will cause ultrasonic reflection when there is a defect in the pipe. The ultrasonic instrument will alarm the ultrasonic reflected signal after realizing the signal to realize the automatic detection of the defect; Transmission ultrasonic pipe testing equipmentis currently the advanced detection equipment in China.

Wireless Transmission Pipe Ultrasonic Flaw Detector Introduction

Rotating probe configuration

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.

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.
