Ultrasonic thickness measurement
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 the speed of sound 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 where:
H-measure thickness;
v-material sound speed;
t - The propagation time of the ultrasonic wave in the test piece for one round trip.
We are familiar with the use of seamless steel pipes for the transportation of fluids used in daily life such as natural gas and water. In addition to these common and familiar natural gas and water transportation, seamless steel pipes are also widely used to transport oil, gas and certain solid materials. The pipeline transportation realized by the seamless steel pipe facilitates people's modern life and greatly reduces the transportation cost of natural resources.
With the growth of time, the probability of steel pipe damage is also very high. At this time, the role of seamless steel pipe comes into play. Seamless steel pipe is the main pipeline used to transport liquids today. Compared with ordinary steel pipes, its strength is higher, its corrosion resistance is stronger, and its service life is increased by more than ten times.
In addition to being the choice for liquid conveying steel pipes, seamless steel pipes are also the main material for making drive shafts on automobiles. After all, the strength of the seamless steel pipe is very high, and the transmission shaft produced will not be easily deformed, which can fully ensure the safety of driving. It can be seen that the help that seamless steel pipes bring to our lives is also very large.
