At the moment, reserves of low-viscosity oil fields are beginning to deplete, and therefore the need for the production of high-viscosity, heavy and bituminous oils is increasing. The difficulty lies in the fact that their transportation from production sites to consumption sites is difficult due to the high viscosity of oil. Currently, the thermal method is widely used to reduce the viscosity of high-viscosity oils. One of the promising and environmentally friendly methods of reducing oil viscosity is the method of using ultrasonic treatment. This paper will investigate the effectiveness of ultrasonic exposure versus thermal exposure to reduce oil viscosity.

The problems of modeling the fracture process under conditions of plastic restructuring of the material structure, the transformation of the strength state of the material of plastically deformable workpieces into the state of the product material, the acoustic emission assessment, which determines the defectiveness of the final product of the predisposition of the workpiece defects to development during the rolling process, are considered.

The ways of increasing the reliability and service life of industrial facilities are considered. The types of hardening technologies and methods of their control are analyzed. An approach that makes it possible to evaluate the quality of hardening technologies based on the registration of acoustic emission (AE) is described. The results of experimental research on the quality of three types of strengthening technologies are presented and the effectiveness of the proposed approach is shown. The obtained results can be used to assess hardening technologies at real facilities in a non-destructive way.
