What diameter of pipes can an ultrasonic thickness gauge measure?
Thread Content
May I ask, what diameter DN of pipes can an ultrasonic thickness gauge measure? Is the wall thickness measurement of DN32 pipes accurate?
The error for wall thicknesses over 1 mm can be kept below 5%
Sure, for small pipe diameters, it’s better to use smaller probes
Check the thickness gauge and probe parameters.
The probe requires a certain degree of curvature; if the tube is too thin, the curvature becomes too large and it’s not possible to position it properly
UT thickness measurement can fully meet the precision requirements, but when measuring very small diameters, conventional probes may not achieve good coupling, leading to errors; military tube thickness gauges are equipped with specialized probes to address this coupling issue. DN32 is no problem.
