Ductile iron pipes are widely used in many fields, mainly including water supply, drainage, gas transmission, industrial applications, agricultural irrigation, roads and transportation facilities, etc.

1. In water supply systems, ductile iron pipes are widely used due to their high strength, corrosion resistance and good sealing performance. Its inner wall is smooth, which reduces water flow resistance and ensures water safety and cleanliness. In addition, ductile iron pipes adopt flexible interface design, good sealing performance, reduce leakage and seepage, and meet drinking water hygiene standards.

2. In drainage and sewage systems, ductile iron pipes can withstand corrosive substances in sewage and ensure smooth discharge and treatment of sewage. It has strong chemical corrosion resistance, can withstand high pressure, and keep the pipeline stable. The interface design is convenient for maintenance, reducing maintenance time and cost.

3. In gas transmission systems, ductile iron pipes are widely used due to their sealing and deformation resistance. Due to its strong material and strong seismic resistance, it can remain stable under complex geological conditions and ensure the safety of gas transmission.

4. In the industrial field, ductile iron pipes are used to transport various industrial fluids and gases. It has strong corrosion resistance and wear resistance, can withstand high pressure and corrosive substances in industrial fluids, and ensure the continuity and stability of industrial production.

5. In the field of agricultural irrigation, ductile iron pipes are widely used due to their corrosion resistance, high strength and long life. It adapts to various soil and climatic conditions, ensures the stable operation of the irrigation system, reduces water waste and improves irrigation efficiency.

6. In road construction and transportation facilities, ductile iron pipes are used to construct drainage systems and other related facilities. It can withstand heavy loads and vibrations, is not easily damaged after long-term use, reduces maintenance costs, ensures unobstructed drainage systems for roads and transportation facilities, and improves driving safety.
