Results of testing a technique for evaluating damages on the inner surface of austenitic-steel pipe samples by the spectral acoustic method with the use of an acoustic phased antenna array are provided. It is shown that accumulated damages can be revealed in the surface layer at a level of 10% of exhausting the resource of an article made of 12Kh18N10T steel.
