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, it is called this. Graphite in ductile iron pipes is a spherical form, and the size of graphite is generally 6-7 grades. In terms of quality, it is required that the spheroidal grade of cast iron pipe is controlled to be 1-3, and the spheroidal rate is ≥80%, so the mechanical properties of the material itself have been better improved, with the essence of iron and the properties of steel. After annealing ductile iron pipe, its metallograph structure is ferrite and a small amount of pearlite, good mechanical properties, 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, easy installation, mainly used for water supply and gas transmission in municipal industrial and mining enterprises.
