Centrifugal ductile iron pipe
Product Introduction：
Stone black in ductile iron pipes exists in a spherical form, with a general size of 6-7 levels. In terms of quality, it is required that the spheroidization grade of cast iron pipes be controlled at level 1-3, with a spheroidization rate of 280%. Therefore, the mechanical properties of the material itself have been well improved, possessing the essence of iron and the properties of steel. After annealing, ductile iron pipes have a metallographic structure of ferrite with a small amount of pearlite and good mechanical properties, so they are also called cast iron steel pipes.
Characteristics: It has the essence of iron, the properties of steel, excellent anti-corrosion performance, good ductility, and easy installation. It is mainly used for water supply and gas transportation in municipal industrial and mining enterprises.
