Seamless steel pipe wall thickness detection method

The ultrasonic thickness measurement method adopts high-performance, low-power microprocessor technology, and based on the principle of ultrasonic measurement, it can measure the thickness of seamless steel pipes, and can measure the sound speed of materials.

Measurement principle

The ultrasonic thickness measurement method is that the ultrasonic pulse generated by the probe passes through the couplant to reach the measured object, part of the ultrasonic signal is reflected by the bottom surface of the object, the probe receives the echo reflected by the bottom surface of the measured object, and accurately calculates the round-trip time of the ultrasonic wave, and press Calculate the thickness value with the formula, and then display the calculation result.

H=(v×t)/2

In the formula:

H-measure thickness;

v-material sound speed;

t - The propagation time of the ultrasonic wave in the test piece for one round trip.
