As the top choice for water supply and drainage pipes in modern infrastructure, high-performance ductile iron pipes are produced by centrifugal casting of molten iron with spheroidizing agents added. They combine mechanical properties similar to carbon steel with the corrosion resistance of cast iron, featuring high strength, toughness, corrosion resistance, wear resistance and easy installation. After rigorous annealing, their microstructure and mechanical properties are further optimized, enabling them to withstand ground settlement and harsh environments stably, with a long service life and low maintenance costs, and their convenient interfaces meet the needs of efficient municipal engineering construction.
