PIPELINE CRACK DETECTION |
| 摘要 |
A method includes emitting an ultrasonic signal into a test specimen from a transducer, receiving a first reflected ultrasonic signal from the test specimen, wherein the first reflected ultrasonic signal is reflected from a feature in the test specimen and the first reflected ultrasonic signal is internally reflected within the test specimen three times prior to being received, and determining a threshold depth of the feature in the test specimen based on receiving the first reflected ultrasonic signal. |
