1. Centrifugal ductile iron pipes combine the ductility, high strength, and pressure resistance of steel with the corrosion resistance of gray cast iron.

2. The elongation can reach over 10%. Centrifugal ductile iron pipes have a tensile strength greater than 420MPa and a pressure resistance of over 4MPa, making them particularly suitable for high-pressure, high-deformation-resistant pipeline systems for water supply, gas transmission, and oil transportation.

3. Ductile iron pipes, supplemented with防腐 measures such as zinc spray and painting, exhibit excellent corrosion resistance and a long service life.

4. The installation process is straightforward and convenient, with cost-effective construction costs.

5. High Reliability: Centrifugal ductile iron pipes have excellent pressure-bearing capacity and a certain degree of elongation. Seamless square tubes also feature flexible joints, allowing for an axial offset of 3-5 degrees without any medium leakage or penetration, demonstrating strong seismic resistance and prevention against subsidence beneath the foundation.
