Pipeline inspection for cracks and corrosion through intelligent inline tools relies on ultrasonic probes, demanding a 100% first-run success rate to minimize costs. These probes face harsh environmental conditions within pipelines, necessitating utmost stability for optimal functionality. Material selection and rigorous testing during development contribute to achieving high stability, yet not every application is anticipated. Conducting individual tests, considering factors like medium, pressure, and temperature, becomes crucial to assess inspection feasibility beforehand. The text outlines this testing process, detailing realistic conditions the ultrasonic probes encounter. Criteria for evaluating probe stability and integrity are elucidated, with practical examples. This approach ensures effective ultrasonic inspection while maintaining cost efficiency.
