Ductile iron pipe water main component of carbon, silicon, manganese, sulfur, phosphorus and magnesium. On the ferrite and pearlite matrix distributed a certain number of spherical graphite, different caliber and in accordance with the requirements of the elongation of the nominal ratio of the matrix structure of ferrite and pearlite different, small-diameter ratio of pearlite generally not more than 20%, large diameter generally controlled at about 25%. Minimum tensile strength: 420 / Mpa, minimum yield strength 300 / Mpa, the minimum elongation of 7%. Ductile iron pipe performance standards GB / T13295-2008 ISO2531 / 2008.
