China's Largest! Taiyuan Heavy Machinery's 2800mm Straight-Seam Welded Pipe Mi
October 23,2026
Advancing its transformation in an orderly, tailored manner to cultivate new quality productive forces, Taiyuan Heavy Machinery recently put its domestically developed, China-largest 2800mm straight-seam welded pipe mill into successful operation at a customer site, another achievement in the company's deep commitment to advanced manufacturing and the cultivation of new quality productive forces.
Straight-seam welded pipe is a key basic material for energy transmission and major engineering construction, often called the main artery of energy and material transport. During the 15th Five-Year Plan period, China will accelerate the building of six major networks, including interconnected underground pipeline networks, driving sustained growth in demand for large-diameter straight-seam welded pipe. As the core equipment of the production line, the mill's maximum specification and weld quality directly determine the maximum diameter, pressure-bearing performance and overall quality of the finished pipe. Targeting the industry's frontier needs, Taiyuan Heavy Machinery delivered a hard-core answer through full-force breakthroughs and independent innovation.
As the largest domestically developed straight-seam welded pipe mill, the equipment can produce pipes with diameters from 600 to 2800mm, helping customers manufacture more efficient transport products and effectively boosting their global market competitiveness in the ultra-large-diameter pipe segment. Abandoning the traditional ring-frame design, it optimizes the frame structure for simpler manufacturing and on-site installation, sharply shortening the production cycle and maximizing delivery efficiency. Its intelligent automatic seam-centering system enables full-process intelligent alignment, reducing manual deviation and ensuring consistent pipe quality. Under dual-carbon goals, high-end equipment must both produce well and save energy: the mill is equipped with high-efficiency energy-saving motors that cut power consumption by up to 25% versus traditional models, achieving both efficient production and environmental protection.
A nation's heavy machinery is defined not only by its scale but by its strength. Metallurgical equipment has long been a hallmark of Taiyuan Heavy Machinery, from its sustained leadership in straightening equipment, to self-reliant seamless steel pipe systems, to extreme breakthroughs in large-diameter straight-seam pipe equipment. Every step reinforces homegrown, controllable industrial confidence and strengthens the backbone of advanced manufacturing.
Again and again setting records and pushing limits, Taiyuan Heavy Machinery is always on the move!
