China's First! Taiyuan Heavy Industry's Another Pipe-Rolling 'Magic Weapon'
October 29,2026
In the early hours today, while the autumn city was still asleep, a steel plant user's production site in Shanxi was brightly lit and bustling. Amid waves of cheers, a large-diameter seamless steel pipe rolled out red-hot, marking the successful hot commissioning of the Φ273 dual-side-out continuous rolling pipe mill independently developed by Taiyuan Heavy Industry.
This red-hot Φ273 mill is the second set of the same type of continuous rolling pipe mill the company has supplied to this user. Not long ago, its "sibling" equipment—China's first Φ180 dual-side-out continuous rolling pipe mill—passed its hot test and has now been running stably at the user's site for over a month. One successful hot test validates the performance of a single mill; two production lines in place validate a complete, reliable technical solution. From the Φ180 mill to the Φ273 mill, Taiyuan Heavy Industry has successfully broken through foreign technology barriers, giving high-end seamless steel pipe equipment a self-controlled "China solution." At the hot test site, the user exclaimed with heartfelt admiration: "Taiyuan Heavy Industry is amazing!"
Behind the user's recognition lies Taiyuan Heavy Industry's technical excellence. The Φ273 mill's R&D team broke through the large-expansion piercing process requirements and developed a 350-pass system, achieving a maximum finished pipe outer diameter of 325 mm rolling capability, successfully meeting the user's rolling needs for large-diameter seamless steel pipes. In addition, the equipment is equipped with the company's self-developed intelligent process model system, linking the full-process coordination of piercing, continuous rolling and sizing, enabling automatic process optimization and automatic equipment fault diagnosis to support the user's intelligent production.
Behind the user's recognition also lies Taiyuan Heavy Industry's speed of delivery. For the user, an earlier production line connection means an earlier grasp of the market window. The Φ273 mill was approved, landed and fully connected within the same year; the company team turned a full year's calendar into a single work order—R&D, design, manufacturing, commissioning... passing the baton seamlessly, link by link, using "high speed + high quality" "Taiyuan Heavy Industry efficiency" to support the user in seizing the initiative in the high-end seamless steel pipe market.
Through each innovation breakthrough, what Taiyuan Heavy Industry delivers is the confidence to help users win the future, and an answer sheet of heavyweight equipment that leads industry upgrading through technological innovation!
