The essence of cast iron steel pipe is ductile iron pipe, because ductile iron pipe has the essence of iron and the performance of steel, so it is called this. Graphite in ductile iron pipes exists in spherical form, and the size of general graphite is 6-7 grades. In terms of quality, it is required that the spheroidization level of cast iron pipes should be controlled at 1-3 levels, and the spheroidization rate should be ≥ 80%. Therefore, the mechanical properties of the material itself have been better improved, and it has the essence of iron and the performance of steel. After annealing, the metallographic structure of the ductile iron pipe is ferrite plus a small amount of pearlite, and the mechanical properties are good, so it is also called cast iron pipe.

Features: It has the essence of iron, the performance of steel, excellent anti-corrosion performance, good ductility, and easy installation. It is mainly used for water supply and gas transmission in municipal industrial and mining enterprises.
