Ultrasonic Wall Thickness Mapping
Ultrasonic wall thickness mapping is an automated testing method that checks corrosion and remaining wall thickness of pipes and vessels. It produces detailed thickness images.
Physicochemical mechanism of action
Ultrasonic wall thickness mapping uses ultrasonic waves that travel through the material and reflect off the surfaces. The time it takes for the waves to return is measured and converted into wall thickness.
Metallurgical relevance & risks during welding
This method is particularly important for pipes and vessels under pressure, since corrosion and wall thinning affect safety and service life. Incorrect interpretation or technical issues can lead to inaccurate results, posing operational risks.
Workshop practice & instructions
Use high-quality ultrasonic devices with high resolution. Make sure the pipe or vessel is clean and dry. Perform the inspection in a quiet environment to minimize interference. Carefully document all steps and results.
