Taiyuan Heavy Machinery Group (太原重型机械集团有限公司, abbreviated 太重) announced on 21 October that its self-developed 2,800 mm straight-seam welded pipe machine had recently been successfully put into production at a customer's site, according to IT Home. CLS and Jiemian reported the same news from the company, calling it the largest such machine in China. [ 1 , 2 , 3 ]
IT Home, citing the company's official introduction, said the machine can make straight-seam welded pipe of 600 to 2,800 mm in diameter. Jiemian gave the same range and said the machine helps the customer make products with higher transport efficiency and improves its global competitiveness in extra-large-diameter welded pipe. [ 1 , 3 ]
IT Home described straight-seam welded pipe as a key material for energy transport and major construction, calling it the main artery of energy and materials transport. It said China will speed up building six networks during the 15th Five-Year Plan period, including interconnected underground pipe networks, and that demand for large-diameter straight-seam pipe keeps rising. It added that the pipe machine's size limit and welding quality directly determine the maximum diameter, pressure resistance and overall quality of the finished pipe. [ 1 ]
CLS reported that the commissioning raises the domestic size limit for straight-seam welded pipe machines and strengthens domestic equipment in this field. It said this helps secure equipment supply and keep costs controllable for oil and gas pipeline construction, and lowers reliance on foreign equipment for key machinery. The documents do not name the customer or the site. [ 2 ]
Why it matters
CLS said the commissioning raises the domestic size limit for such machines and helps secure equipment supply for oil and gas pipeline building while reducing reliance on foreign equipment. IT Home linked demand for large-diameter pipe to China's planned expansion of pipe networks. These points come from the company's announcement and outlet commentary.
