What is ductile iron pipe?
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Execution standard GB/T13295-2003ISO2531/2003
Ductile iron pipe is a kind of cast iron pipe. In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the material have been better improved, with the nature of iron and the properties of steel. Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Ductile cast iron is defined using the above number 18 by adding nodulizer, after centrifugal ductile cast iron machine centrifugal cast pipe, ductile iron pipe (called [span]Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..
