Ductile Cast Iron Pipe

     Ductile cast iron pipe, is consist of iron/ carbon/ silicon alloy etc and among    them the carbon exists in the form of speroidal graphite.    Grey iron, is existed in the form of flake carbon which has the effect of    cutting the iron matrix and can lead brittle and easy to crack.    The speroidal graphite of ductile iron appear as small spheres and    eliminate the risk of crack propagation can lead tough to tensile.    Ductile iron pipes have the nature of iron and characters of steel.
