Performance Of Ductile Iron Pipe

Ductile Iron is a metal that entered the market in 1955. It retains all the characteristics of cast iron, such as workability and rust resistance, as well as stronger endurance, lighter weight and robustness. Ductile iron pipes are increasingly favored by various other pipe materials, such as PVC, polyethylene, steel and concrete, and are used in countless water and wastewater systems today.

Ductile iron pipe is a kind of cast iron, which is an alloy of iron, carbon and silicon. The graphite in ductile iron is spherical. Generally the size of graphite is 6-7. The quality requires that the spheroidization level of the cast pipe be controlled within 1-3 (spheroidization rate ≥80%), so the material itself is mechanical, and the performance has been better improved, with the essence of iron and the performance of steel. The annealed ductile iron pipe has a metallographic structure of ferrite plus a small amount of pearlite, and has good mechanical properties. Ductile iron pipes are mainly called centrifugal ductile iron pipes. It has the essence of iron, the performance of steel, excellent anti-corrosion performance, good ductility, good sealing effect, and convenient installation. It is mainly used for water supply, gas transmission, and transportation in municipalities, industrial and mining enterprises. It is the first choice for water supply pipes, and it is cost-effective. Compared with PE pipes, ductile iron pipes are easier and faster to install than PE pipes in terms of installation time, and have better internal and external pressures after installation; from the perspective of airtightness and corrosion resistance, ductile iron pipes have better airtightness after installation, and various anti-corrosion methods can be used to improve the anti-corrosion performance; from the perspective of hydraulic performance, because the specification of ductile pipe generally refers to the inner diameter, the specification of PE pipe generally refers to the outer diameter. From the perspective of comprehensive installation and maintenance costs, ductile pipes have a more superior cost performance. The inner wall is sprayed with zinc, cement mortar and anticorrosive materials.
