Ductile iron pipe is a kind of cast iron, the graphite in it is spherical, and the quality requirements are also very strict, because the mechanical properties of its material itself are relatively ideal, ductile iron pipe not only has the essence of iron, but also has Just performance.
In terms of use, cast iron pipes are not only widely used in building drainage and sewage treatment, but also in the treatment of industrial wastewater. It can be seen that it is used in larger pipes and is also suitable for areas with an earthquake intensity below 9 degrees. , and the ductile iron pipes are very excellent in terms of anti-corrosion performance and sealing effect, such as some municipal construction, as well as water and gasoline transportation in industrial and mining enterprises, are very good

It is mainly used for water supply, gas transmission and oil transportation in municipal, industrial and mining enterprises. A certain amount of spheroidal graphite is distributed on the ferrite and pearlite matrix. According to the different nominal diameter and requirements for elongation, the proportion of ferrite and pearlite in the matrix structure is different. The proportion of pearlite with small diameter is generally not more than 20%, and that of pearlite with large diameter is generally controlled at about 25%
