Ultrasonic Wall Thickness Echo Tracking
Ultrasonic wall thickness echo tracking precisely measures the remaining wall thickness of pipelines via echo time-of-flight. Used for in-service inspections to detect erosion or corrosion.
Physicochemical mechanism of action
Ultrasonic wall thickness echo tracking uses ultrasonic waves that are reflected at the pipe wall. The echo's travel time is measured and converted into wall thickness. This allows precise wall thickness detection.
Metallurgical relevance & risks during welding
If handled incorrectly, this process can lead to inaccurate measurements, resulting in inspection errors and potential safety risks in the pipe network. It is essential that the ultrasonic device is correctly calibrated and the pipes are clean.
Workshop practice & instructions
Use a high-resolution ultrasonic device with high frequency. Make sure the pipe is clean and free of dirt layers. Measure the echo travel time at several points along the pipe and compare the results with the specific standard values for the material type and pressure system.
