DUCTILE IRON PIPE

Ductile iron pipes, made from ductile iron material, are known for their core characteristics of high strength, excellent corrosion resistance, and easy installation. Ductile iron is produced by adding a suitable amount of nodulizing agent during the casting process, which transforms the graphite in the iron into spherical shapes, significantly enhancing the mechanical properties of cast iron.

The main advantages of ductile iron pipes are:

1. High Strength: Ductile iron is much stronger than gray cast iron, with a tensile strength exceeding 420 MPa, making it suitable for high-pressure applications.
2. Excellent Corrosion Resistance: Ductile iron pipes outperform steel pipes in terms of corrosion resistance, with a service life of over 50 years and resistance to various corrosive environments.
3. Easy Installation: Ductile iron pipes have flexible joints that simplify installation, reduce construction time, and save on costs.
4. Cost-Effective: Despite their initial higher cost compared to gray cast iron pipes, ductile iron pipes offer superior long-term cost-effectiveness due to their extended service life and low maintenance requirements.

Ductile iron pipes are widely used in urban water supply, drainage systems, natural gas transmission, and other applications, playing a vital role in modern urban infrastructure.
