Hypothesis
A new method for determining the initial excitation load of the acoustic field is proposed to improve the accuracy of ultrasonic internal inspection of pipelines.
Conclusion
The new method significantly improves the accuracy of wall thickness inversion during ultrasonic internal inspection of pipelines.
Supporting Evidence
- The new method incorporates the focusing effect of the curved surface of pipelines on ultrasonic signals.
- Comparisons with actual wall thickness showed improved accuracy using the new method.
- The study lays the groundwork for a digital platform for ultrasonic internal detectors.
Takeaway
This study found a better way to measure how ultrasonic signals work in pipelines, which helps to find problems like cracks more accurately.
Methodology
Finite element models were established for both new and old methods using COMSOL software to analyze the initial acoustic field distribution and electrical signal characteristics.
Limitations
The study may not account for all real-world conditions affecting ultrasonic signal propagation.
