Temperature Effect on UT

Dear Friends,
What is effects of high temperature on sound velocity in matrials .for example in thickness measuring of c.steels on 500 oC what is the changing of actual thickness which detected by UT?
Regards

Re: Temperature Effect on UT
Sound velocity in all engineering materials decreases with temperature. In common steel alloys, the velocity decreases approximately 1% per 55 degrees Celcius. Thus, if you do not compensate for this change, your thickness readings at elevated temperature will be too high.

We have an application note on the subject of high temperature testing that you may find useful. Please see the link below.

you can elevate the temperature of your calibration block to 500oC and UT thickness readings will be accurate

mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
