Ultrasonic testing of steel pipes
Ultrasonic testing is a widely used technique for evaluating the structural integrity of steel pipes in various industries. The use of ultrasonic waves to assess the quality and defects in steel pipes is based on the principles of sound reflection, attenuation, and transmission.
We apply an electrical pulse to the probe and vibrate the piezoelectric chip in the probe to produce ultrasonic waves. Ultrasonic waves transmit at a certain speed in steel pipes. When defects appear, some of the sound waves are reflected back, while the other part continues to propagate forward. The sound waves reflected by the defects are received by the probe, and then converted into electrical pulses through the piezoelectric chip of the probe. After being amplified by the instrument, they are displayed on the fluorescent screen of the instrument.
Ultrasonic testing can inspect defects such as cracks, corrosion, and voids in steel pipes. These defects can cause the sound waves to scatter or be absorbed, which can be detected and analyzed to identify the location and severity of the defect.
