At the beginning of 2026, the industry witnessed a milestone achievement. The world's first 2.8-meter diameter (DN2800) ultra-large diameter ductile iron pipe has been successfully applied in the Jiulongjiang Water Diversion Project in Zhangzhou, Fujian Province — a key national project under the "14th Five-Year Plan."
Advantages and disadvantages of ductile iron pipes lined with cement compared to other pipes! The main components of ductile iron pipes include carbon, silicon, manganese, sulfur, phosphorus, and magnesium. They comply with the standards GB/T13295-2003 and ISO2531/2003, and feature excellent corrosion resistance, good ductility, and superior sealing. They are easy to install and are mainly used for water supply, gas transmission, and oil transportation in municipal, industrial, and mining enterprises.
