What are the advantages of ductile iron pipes?

In medium and low-pressure pipelines (typically used for pressures below 6MPa), Ductile Iron Pipes offer reliable operation, low failure rates, easy and quick construction and maintenance, and excellent corrosion resistance. The newly developed "Rock Shield" series pipelines are suitable for non-excavation construction and are widely used in pipeline projects across rivers, through roads, and under buildings. The "Saiyin" series pipelines, on the other hand, utilize a special zinc-aluminum alloy exterior spraying process to multiply the corrosion resistance of the pipes, making them widely applicable in construction in strongly corrosive soils.
