Recently, the independently developed welded hollow sucker rod by Tuha Petroleum Exploration and Development Command Machinery Factory has successfully passed the identification process conducted by Tuha Oilfield and has officially entered mass production. Since last year, the factory has been conducting in-depth technical research on the structural design and manufacturing process of hollow sucker rods, building upon its existing production line for welded solid sucker rods. Based on the outcomes of this research, the factory has completely upgraded its original production facilities, integrating advanced equipment such as the American Leitai dual-color infrared penetrating temperature measurement system. This modernization has enabled the production of hollow sucker rods with precise quenching and tempering temperature control, reliable friction welding quality, and significantly improved production efficiency. The new production line not only meets industry standards but also fills a critical gap in the western region's manufacturing capabilities for hollow sucker rods. With this achievement, the factory is now well-positioned to meet growing market demands while enhancing its competitive edge in the oilfield equipment sector.
