The technology of acoustic testing of pumping and compression pipes with use of torsional waves is described; the technology is based on waveguide effects of a multiple reflection method. Formulas for an acoustic tract when employing the multiple reflection method are offered. The main informative parameters of the method are presented, they are: ratios of reflection from a defect for the 1st and nth reflections; attenuation ratio; torsional wave velocity. Statistical data of rejected pipes distribution based on informative parameters aggregation are given; the data have been obtained during industrial usage of acoustic flaw detector ADNKT at pipes maintenance. Possibilities are shown for defects location of various types in pumping and compression pipes both new and used.
