Ductile iron pipes refer to pipes made by high-speed centrifugal casting of cast iron with a diameter of 18 or above, after adding spheroidizing agents, using a centrifugal ductile iron machine. They are commonly referred to as ductile pipes, ductile iron pipes, and ductile iron pipes. Mainly used for the transportation of tap water, it is an ideal material for tap water pipelines.
