Способ относится к газо- и нефтедобыче и транспортировке, в частности к методам неразрушающего контроля трубопроводов при их испытаниях и в условиях эксплуатации. С помощью установленных на поршневом элементе, расположенном в трубопроводе в текучей среде, преобразователей излучают прямой сигнал, принимают и регистрируют сигналы, отраженные от внутренней и внешней поверхностей трубопровода, а также от поверхности дефектов, образовавшихся в трубопроводе. Излучение и прием осуществляют дважды, например один раз для давления текучей среды перед поршнем, второй раз для давления текучей среды за поршнем, по разнице сигналов выявляют дефекты и определяют их параметры. Способ обеспечивает повышенную точность определения дефектов трубопроводов.The method relates to gas and oil production and transportation, in particular to methods of non-destructive testing of pipelines during their testing and under operating conditions. Using transducers installed on a piston element located in a pipeline in a fluid medium, they emit a direct signal, receive and record signals reflected from the internal and external surfaces of the pipeline, as well as from the surface of defects formed in the pipeline. Radiation and reception are carried out twice, for example once for the pressure of the fluid in front of the piston, a second time for the pressure of the fluid behind the piston, defects are detected by the difference of signals and their parameters are determined. The method provides improved accuracy in detecting pipeline defects.
