Ductile iron pipe

Ductile iron pipe is a new type of metal pipe, ductile iron pipe pressure resistance in more than 3MPa, pipe diameter 80 ~ 2000mm, the effective length of 4 ~ 6 m. With the corrosion resistance of cast iron pipe and steel pipe toughness and strength, but also has the advantages of impact resistance, vibration resistance, thin-walled and so on, is widely used in towns and cities in the water supply, drainage, gas transmission projects.

Ductile iron pipe production method is to magnesium or rare earth magnesium alloy spheroidal agent added to the iron water before pouring, so that graphite spheroidization, while adding a certain amount of ferrosilicon or calcium silicon alloy as a breeding agent to promote graphite precipitation spherical.

Features:
Ductile iron pipe is a kind of cast iron pipe. Quality requirements of cast iron pipe spheroidization grade control for 1-3 (spheroidization rate of “80%), and thus the mechanical properties of the material itself has been better improved, with the nature of iron, steel performance. Annealed ductile iron pipe, its metallurgical organization for ferrite plus a small amount of pearlite, good mechanical properties, excellent anti-corrosion properties, ductility, good sealing effect, easy to install, mainly used in municipal, industrial and mining enterprises for water supply, gas, oil and so on.
In the ferrite and pearlite matrix on the distribution of a certain number of spherical graphite, according to the nominal caliber and the different requirements of the elongation, the matrix organization of ferrite and pearlite in different proportions, the proportion of pearlite in the small diameter is generally not more than 20%, the general control of the large diameter of about 25%.
