Abstract
Способ определения местоположения негерметичности стенки трубы на участке магистрального трубопровода, основанный на последовательной регистрации следующих за возникновением негерметичности импульса давления и изменения спектра акустических шумов среды, заполняющей трубопровод, в области его высокочастотных компонент, отличающийся тем, что регистрируют дополнительную высокочастотную компоненту спектра акустических шумов, вызванную нарушением герметичности стенки магистрального трубопровода, после возникновения последовательности однократного скачка амплитуды вибраций металла трубы и следующего за ним однократного импульса избыточного давления в среде, заполняющей трубопровод.A method for determining the location of a pipe wall leak in a section of a main pipeline, based on the sequential registration of a pressure pulse following leakage and a change in the acoustic noise spectrum of the medium filling the pipeline in the region of its high-frequency components, characterized in that an additional high-frequency component of the acoustic noise spectrum is recorded, caused by violation of the tightness of the wall of the main pipeline, after the occurrence of the follower a single jump in the amplitude of vibration of the pipe metal and the subsequent single pulse of excess pressure in the medium filling the pipeline.
