It is established by calculation that in the regimes of the cleaning of the steel tubes of diameter 56 x 3 and 76 x 3 mm, for example, by the electrohydroimpulse (EHI) technique with discharge in the liquid - and particularly in the continuous deposit layer of thickness 5-8 mm - the amplitude of the pressure in the discharge channel is several times the ultimate compressive strength of the strong deposits (sigma_(com) > 40 MPa). The governing role in the deposit fracturing process is that of the pressure pulse of the primary electric discharge in the channel in the deposit layer. There are three tube segments that are characteristic for the EHI cleaning process and two regions of crack formation ahead of the fracturing front. We examine the reasons for the appearance of the fracturing process, the cracks in the deposits, and the appearance and the propagation of the primary and reflected fracture fronts.
