Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development in Chemical Engineering Equipment】A continuously updated summary post – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On November 1, 2025, China’s steel industry reached a historic moment. China’s first and also the world’s largest 530 Assel skew rolling tube production line was officially put into operation at Shandong Guangfu Group. This news shocked the entire industry. China’s first 530 Assel skew rolling tube production line was officially put into operation, marking a significant advancement in the country’s high-end equipment manufacturing sector as well as its leadership in global seamless steel tube production. The research and development of this production line was carried out with great effort by Taiyuan Heavy Machinery Group. Its commissioning not only marks significant progress in China’s high-end equipment manufacturing industry, but it also signifies that we have achieved self-sufficiency in the field of large-diameter, thick-walled seamless steel pipes. This allows us to break free from dependence on others and truly become a leader in global seamless steel pipe production. Well, these top-quality seamless steel pipes have always had to be imported; not only are they expensive, but the procurement process is also time-consuming, and there is even a risk of supply disruptions. However, we now possess independent production capabilities, which not only enable rapid response but also significantly improve product quality. Known as the world’s largest and China’s first of its kind production line, its core competitiveness lies not merely in the breakthrough in size, but rather in a comprehensive set of innovative technologies that we have developed independently. The adoption of a dual-closed-loop and dual-circuit hydraulic coordination control system has significantly improved the efficiency and quality of steel pipe production. Firstly, this production line innovatively employs a dual-closed-loop and dual-circuit hydraulic coordination control system. This system is akin to equipping the rolling mill with sharp visual and neural reflex mechanisms; one of the closed-loop systems enables precise control over the position of the rollers, while the other adjusts the rolling force in real time. This precise coordination achieves a response time on the order of milliseconds, significantly reducing deformation issues of the steel pipe during finishing. Compared to traditional processes, this system can release pressure rapidly, thereby ensuring consistent quality of the entire steel pipe throughout the production process.
The achievements of Taiyuan Heavy Machinery Group: As a pioneer in the manufacturing of heavy machinery in New China, Taiyuan Heavy Machinery Group has set over 500 records, both in China and around the world. From the world’s largest 5600mm straightening machine, to the globally first +305 piercing machine, and now the M530 skew rolling tube mill, they continue to explore and break new ground at the boundaries of equipment manufacturing. Taizhong Group continues to make breakthroughs in the field of equipment manufacturing; user feedback confirms its achievements, ensuring the safety and stability of the industrial chain. The genuine feedback from our client companies has further strengthened our confidence; their satisfaction and recognition are the best proof of Tai Chong Group’s unremitting efforts. This not only highlights the company’s outstanding achievements but also ensures the safety and stability of the industrial chain. ◉ The status and impact of key materials: Achieving self-sufficiency in key materials has enabled steady development in the fields of energy, infrastructure, and defense. Perhaps you don’t come into direct contact with this 530-millimeter steel pipe in your daily life, but it silently supports infrastructure such as power grids, oil and gas pipelines, and offshore platforms, bringing tangible convenience and safety to your life. The self-sufficient 530 steel pipes ensure progress in the fields of energy, infrastructure, and defense, bringing convenience and safety to daily life. The power of Chinese manufacturing lies in these unassuming corners, quietly supporting the prosperity and stability of **.
