Materials and Properties of Ductile Iron Pipes

Ductile iron pipe is a kind of cast iron pipe. In terms of quality, the spheroidization grade of cast iron pipe is required to be controlled as Grade 1-3 (spheroidization rate is 80%), so the mechanical finished ductile iron pipe warehouse of the material itself can be better improved, with the essence of iron and the properties of steel. The metallographic structure of the annealed ductile iron pipe is ferrite plus a small amount of pearlite, which has good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, and is mainly used for municipal, industrial and mining enterprises water supply, gas transmission, oil transmission, etc.
