Ultrasonic Pipe Wall Thickness Gauge

By utilizing the property of ultrasonic waves propagating and reflecting within materials, a probe emits high-frequency sound waves into the pipeline, receives the echoes, and calculates the round-trip time of the sound waves. Combined with the sound velocity of the material, the wall thickness of the pipeline is determined. This method is used to detect pipeline corrosion and wear and is applied in regular inspections in industries such as chemical and petroleum.
Selection
Select the appropriate sound velocity setting based on the material of the pipe being tested. Determine the probe size and type by considering the pipe diameter and curvature. Use the corresponding couplant according to the temperature range. Check whether the instrument's measurement range covers the expected thickness. Verify that the data storage and transmission functions meet the recording requirements.
