Recently, the welded hollow sucker rod independently developed by the Machinery Factory of Tuha Petroleum Exploration and Development Command 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 the existing production line for welded solid sucker rods. Based on these research outcomes, the factory has completely renovated its original production line, incorporating advanced equipment such as the American Leitai two-color infrared penetrating temperature measuring instrument. This 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 newly established production line has effectively filled the gap in the manufacturing of hollow sucker rods in the western region, marking a major technological breakthrough for the local oilfield industry. This development not only enhances the competitiveness of the factory but also supports the sustainable development of oil extraction operations in the area.
