METHOD OF DETECTING DEFECTS OF MAIN PIPELINES BY THE METHOD OF ACOUSTIC TOMOGRAPHY Russian patent published in 2019 - IPC G01N29/14 

Abstract RU 2681424 C1

FIELD: defectoscopy.

SUBSTANCE: using: for non-destructive testing and detection of defects in trunk pipelines in their complex stress state. Summary of Invention thing is carry out the primary conversion of acoustic oscillations with the use of binary sign analogue-stochastic quantization. At the moments of changing the sign of the result of a binary sign analogue-stochastic quantization, digital sample codes are formed, which determine the mutual correlation function for positive and negative delay values, fix the delay time for the maximum value of the mutual correlation function and determine the location of the defect in the controlled section of the pipeline.

EFFECT: making it possible to simplify the process of locating the defect.
