Multiple automated pipe production lines at Jiangsu Dejing Pipeline Systems Technology Co Ltd commenced trial operations recently within the Qingshan (Jingjiang) Stainless Steel Deep Processing Industrial Park located within the Jingjiang Economic and Technological Development Zone in Taizhou.
"These large-diameter pipe production lines are independently developed by our company, achieving industry-leading levels of automation," said Mo Peiming, General Manager of the Dejing Pipeline.
With a total investment of 1 billion yuan ($140.17 million), its high-quality stainless steel pipe production project is designed with an annual capacity of 100,000 metric tons. It represents China's largest intelligent stainless steel pipe facility, capable of producing pipes ranging from 6 to 820 millimeters in diameter.
In the workshop, several precision laser welding production lines operate at high efficiency, achieving welding speeds five to eight times faster than conventional methods. The fastest line can produce a 50mm-diameter pipe with 2.5mm wall thickness in just two minutes.
The company primarily supplies high-performance, corrosion-resistant, and pressure-tolerant steel pipes for petroleum, chemical, power, as well as water and gas transmission applications, where welding quality and stability are particularly critical.
"Each pipe undergoes comprehensive examination after production, using radiographic testing methods to ensure precise inspection of weld seams and guarantee product quality," said Mo.
Dejing Pipeline is currently advancing equipment installation and debugging, with all production lines expected to be fully operational by year-end.
