    Hot-expanded steel pipe refers to a steel pipe with relatively low density but strong shrinkage, and a waste pipe finishing rolling process in which the diameter of the pipe is enlarged by the cross-rolling method or the drawing method. In a relatively short period of time, thickening steel pipes can produce non-standard and special types of seamless pipes, with low cost and high production efficiency, which is the development trend of the international pipe rolling field.
    The two-step push pipe expander used in the hot expanded steel pipe integrates the taper die expanding technology, the digital intermediate frequency induction heating technology, and the hydraulic technology in one machine. With its reasonable technology, lower energy consumption, lower construction investment, and good The high product quality, wide range of raw materials and product specification applicability, flexible and variable low-input production batch adaptability, replace the traditional pull-and-draw expansion technology of the steel pipe industry.
