Ductile Cast Iron Pipe:NBR,SBR,EPDM Rubber,DN 80 - 1600mm

Ductile cast iron pipe is first choice of water supply pipe,with very high cost-effective.From the installation time,Ductile cast iron pipe is more convenient and efficient to install than PE pipes compared with PE pipes.From the hydraulic performance, for ductile iron pipe specifications generally refers to the inner diameter,and PE pipe specifications generally refers to outer diameter,ductile pipe can realize a greater runoff under the same conditions of specifications.

Product Description

Ductile cast iron pipe is a kind of cast iron pipes, which is an alloy of iron,carbon and silicon. Graphite in ductile cast iron exists in the form of sphere.Generally graphite size is around 6-7 level. On quality require the nodulizing grade of cast iron pipe nodulizing grade to be 1-3 grade. So the mechanical properties of the material itself has been better improved, with the essence of an iron and the performance of a steel. Ductile cast iron pipe after annealing whoes microstructure is ferrite and a pinch of pearlite, which is provided with good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation,ect..
