- Abstract
The paper presents the results of development of portable means for diagnostics of products and structural elements by the parameters of elastic waves of different nature. Structures of multichannel acoustic-emission and magnetoacoustic diagnostic systems were developed. System realization in the form of stacked block structures was substantiated. Design of a mobile device for moving the put-on magnet of the magnetoacoustic system is proposed. System and information software for magnetoacoustic and multichannel acoustic-emission portable systems was developed. A procedure is proposed for evaluation of the stressed state of ferromagnetic structural elements by the parameters of the signal of magnetoelastic acoustic emission. Procedures for controlling the metrological characteristics of the developed systems were elaborated. Acoustic emission and magnetoacoustic inspection of pressure vessels and pipeline sections and equipment of oil and gas complex of Ukraine in Lviv and Ivano-Frankivsk regions was performed. 11 Ref., 6 Fig. [ABSTRACT FROM AUTHOR]
