Ductile iron pipe is mainly used in water supply, drainage, sewage and other industries, with high strength, high elongation, impact resistance, corrosion resistance, good sealing and so on. ‌ In the water supply industry, ductile iron pipe is widely used because of its excellent performance, becoming the first choice of main parts. Its inner wall is lined with cement mortar, which improves the water transmission environment of the pipeline, increases the water supply capacity, and reduces the energy consumption. ‌

The production process of ductile iron pipe includes adding magnesium or rare earth magnesium combined with gold spheroidizing agent before pouring to spheroidize graphite, thereby reducing stress concentration and improving the strength and elongation of the pipe. The installation is simple and fast, and the internal and external pressure is better after installation, and the tightness and corrosion resistance are excellent.

In addition, ductile iron pipe has a higher cost performance compared with PE pipe. Although the installation time of PE pipe may be shorter, the ductile iron pipe can achieve greater runoff under the same specification conditions, and the tightness and corrosion resistance after installation are better.
