Definition and Overview of Ductile Iron

Ductile iron pipes, also known as nodular iron pipes, nodular cast iron pipes, or more commonly, centrifugal ductile iron pipes, are produced by adding nodulizing agents to molten cast iron and then casting it at high speed through a centrifugal ductile iron casting machine. They are abbreviated as DIP (Ductile Iron Pipe). With their superior performance, strong adaptability, and diverse product categories, centrifugal ductile iron pipes are widely used in various fields and have broad development prospects.

Ductile iron, a type of cast iron, is an alloy of iron, carbon, and silicon. In ductile iron, graphite exists in spherical form, generally ranging in size from grade 6 to 7. Quality standards require the nodularization grade of cast pipes to be controlled at grades 1 to 3 (nodularity ≥ 80%), which significantly improves the material's mechanical properties, giving it the essence of iron and the performance of steel. After annealing, the microstructure of centrifugal ductile iron pipes consists of ferrite with a small amount of pearlite. The proportion of pearlite in small-diameter pipes is generally not more than 20%, while that in large-diameter pipes is generally controlled at around 25%, further optimizing the mechanical properties, strength, toughness, and exhibiting excellent pressure resistance and ductility.
