METHOD OF ACOUSTIC INVESTIGATION OF PHYSICAL-MECHANICAL PROPERTIES OF MATERIALS

摘要

The invention relates to nondestructive monitoring means and methods and can be used in particular for ultrasonic inspection of pipelines pipes. The aim of the invention is to provide the possibility of controlling the material with a critical degree of saturation with hydrogen sulfide. For this use the heater 1 is subjected to local heating of the product 8. receives signals from the sensor 3, amplify them, and measured the unit 5. The measured number of the acoustic emission signals is compared with the value obtained when heating a reference sample having a critical degree of saturation with hydrogen sulfide. The method allows to automate the process of evaluating the quality of oil pipes. yl 2
