This article examines the transformation of tubing repair processes through the transition to stationary workshop facilities equipped with automated and robotic cleaning systems. The inefficiency of traditional manual and chemical methods is demonstrated, particularly under severe clogging, which lead to localized thread damage, inconsistent surface quality, and uncontrolled waste generation. The structure of the technological line is presented, including the following modules: input control, comprehensive diagnostics, positioning, hydraulic, plasma and ultrasonic cleaning, drying, non-destructive testing, thread restoration and hydraulic tests. The key element is the introduction of a digital twin and a unified automated process control system, providing end-to-end accounting, adaptive control of processing parameters and cycle forecasting. Based on a review of leading manufacturers’ equipment and analysis of industrial pilot trials, implementation, and commercial operation across the Western Siberian and Volga-Ural regions (2022–2026), significant technological and economic efficiencies are confirmed: throughput increases by 45–65 %, cleaning time is halved, water and reagents consumption is reduced by 40-50 %, and the share of scrap decreases by 70-80 %. Particular attention is paid to environmental safety through the use of closed water recycling circuits and minimizing the presence of personnel in the hazardous area. Recommendations for modular design, selection of proven solutions, AI integration, and workforce training are provided to guide future industry development.
