Experimental studies of wave processes in the pipeline system

Introduction. In order to conduct a qualitative and quantitative analysis of wave processes, as well as to verify the effectiveness of the modern complex, a number of field tests were conducted. These experimental studies were carried out both in controlled laboratory conditions and directly within the production facilities of the real sector of the economy.

Materials and methods. Laboratory tests were carried out on the basis of the Kurgan Centre for Testing, Certification and Standardization of Pipeline Fittings (ANO “KCISS”), an autonomous non-commercial organization in Kurgan, Kurgan region, established to provide services in the field of conformity assessment and quality assurance of equipment, products and technologies, including for nuclear energy facilities, petrochemical, oil and gas production, processing plants and other hazardous industrial facilities and productions, as well as general industrial facilities and productions, including the implementation of measures to improve data security objects. In accordance with clause 7 of the Decision of “Rosenergoatom Concern” dated 26.06.2019 No. R 1.2.2.06.001.0435–2019 “The modernization of the second and third channels of the industrial water system of responsible consumers of Group A of Power unit No. 4 of Kalinin NPP” and clause 6.10 of the terms of license No. GN-03-101-4122 from 10/20/2021. Pressure pulsation values were measured using the developed wave process monitoring system in the process water pipeline systems of responsible consumers of Group “A” 4VF of power unit No. 4 of Kalinin NPP during the transition period of operation associated with the automatic step-by-step start-up of NPP safety equipment.

Results. The results show that, according to the experiments conducted using the developed monitoring system for wave processes, pressure changes in the pipeline system have a high-frequency character, which corresponds to the nature of wave processes.

Conclusions. Experiments under conditions of various non-stationary modes in the diagnosed pipelines have clearly demonstrated the operability of the proposed monitoring system for wave processes in the pipeline system.
