Estimation of the sensitivity of acoustic reflectometry to flaws in heat-exchange pipes

Аннотация

A novel approach to calculating the acoustic tract in the method of acoustic reflectometry is suggested for inspection of heat-exchange pipes. Results of modeling and analysis of the acoustic tract are presented. The sensitivity of acoustic reflectometry to flaws in the form of through holes and deposits against the background of acoustic noises due to permissible deviations in the thickness of the pipe wall is estimated.
