Non-destructive ultrasonic investigation of the structure state of steam pipelines

Ivanova Y. , Partalin T. , Tabakova B.


The main purpose of the work is to study the dependence of the ultrasonic wave parameters on the structure state in tubes of boilers at thermo-electric power station. The changes of the velocity, spectra and attenuation of ultrasonic surface waves are caused by degradation of the structure and can be used for residual life estimation of the equipment.
