Acoustic Waves Propagation in Pipelines

A. V. Zhukov, A. N. Kuzmin

The article deals with questions of experimental survey of acoustic emission waves propagating effects in pipelines with liquid medium. It is found that the wave packet from an acoustic emission elementary source is a combination of Lamb’s elastic waves in pipeline material and longitudinal waves in liquid. The features of the resulting wave packet are studied. The necessity of revising existing methodological regulations for main oil-products pipelines AE testing is substantiated for the purpose of reliability and accuracy increase of critical AE source coordinates determination.
