4220 Large-Diameter Spiral Welded Pipe Mill Finished Installing in China

29 Jul,2025


This 4220 large-diameter spiral welded pipe production line was just finished installing in Jiangsu,China.  This production line utilizes advanced spiral welding technology, enabling the efficient production of large-diameter welded pipes with diameters up to 4220mm. This not only significantly improves production efficiency but also achieves a qualitative leap in pipe quality.

Equipment Specifications:

Plate Width: 500-1550mm 
Pipe Outer Diameter: Φ508-4220mm 
Wall Thickness:8-25 mm  

Workshop Site:

These large-diameter welded pipes are widely used in the construction of long-distance pipelines for oil and natural gas, as well as in large-scale water conservancy and bridge infrastructure projects. Their superior welding performance and strong pressure resistance will provide safer and more reliable support for various engineering projects. In addition, the production line boasts a high level of intelligence. An integrated control system achieves automated and precise management of the production process, effectively reducing energy consumption and labor costs, demonstrating the strong momentum of China's manufacturing industry's transformation towards intelligence and green development. With the official operation of the 4220 large-diameter spiral welded pipe production line, it is expected to further promote the rapid development of China's pipe manufacturing industry and add new luster to "Made in China".
