Specifications of ductile iron pipe

In the urban water supply project, the cost of the water supply pipeline accounts for a relatively large investment in the entire water supply project, accounting for 50-70% of the total cost of the entire water supply project. Therefore, choosing the right pipe and good construction quality is the fundamental guarantee for ensuring the safe operation of the urban water supply pipe network.

The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. A certain amount of spheroidal graphite is distributed on the ferrite and pearlite matrix. The proportion of ferrite and pearlite in the matrix is ​​different according to the nominal diameter and the elongation requirement. The proportion of pearlite in small diameter is small. Generally not more than 20%, the general control of large diameter is about 25%. Minimum tensile strength: 420/Mpa, minimum yield strength 300/Mpa, minimum elongation 7%.
