Ductile Iron Cast Pipe is without any defects compare with tradition casting tech, which has many advantages particularly as follow:
(1) High density. In the "vertical upward casting" process, the melt iron of centre liquid column in center crystallizer is continuously feeding for volume shrinkage caused by condensation tube at outer circumference , which lead to be free of shrinkage porosity.
(2) High purity. When melt iron pouring, the mixed impurities such as gas, dross, sand grain which are lighter than melt iron could be eliminated at furnace mouth, its impossible to enter into the crystallizer through the channel, so the melt iron into the crystallizer is very pure.
(3) Strength with toughness. The cooling speed provided by continuous crystallizer is 30 times than sand casting and 5 times than centrifugal casting, and doesn't produce white iron, the eutectic cell volume of continuous cast iron is one eighth to one tenth compare with traditional cast iron. The density of graphite nodule in ductile iron can reach 300-700 pcs/mm2. Therefore, all reason above improve the strength and toughness of continuous cast iron.
(4) Free machining. The high speed cooling make the hardening phase (such as boride, steadite) not appear like reticular, massive or thick, but diffuse like fish bone and pane in shape, moreover, there are tiny graphite flakes inlaid hardening phase. It's free machining in BrinellHardness the range of 250-300HB. However, the Brinell Hardness of 250 is top limit to common metal materials.
(5) Uniform composition of tube wall. The convection mixing of liquid column caused by marching type drawing in crystallizer make the composition of tube wall well-distributed, and concentration gradient very little.
(6) High productivity. To the wall thickness of tube under 10mm, the speed of continuous casting is 1 meter/min, to the wall thickness of tube under 20mm, the speed of continuous casting is 0.5 meter/min, which is high efficiency that centrifugal or other casting tech couldn't reach.

- Q: What is the weight of ductile iron pipes compared to other materials?
- Compared to other commonly used materials in the construction industry, ductile iron pipes tend to be heavier. The weight of these pipes can vary depending on their specific size and dimensions, but they are usually heavier than materials like PVC, HDPE, and steel pipes. The primary reason for this increased weight is the dense nature of ductile iron, which grants it durability, strength, and resistance to corrosion. However, this weight also presents challenges in terms of transportation, installation, and handling, necessitating appropriate equipment and techniques for safe and efficient installation. Despite being heavier, ductile iron pipes offer numerous advantages in terms of longevity and performance in various applications.
- Q: Do ductile iron pipes require additional protection against external factors?
- Yes, ductile iron pipes do require additional protection against external factors. While ductile iron is known for its strength and durability, it is still susceptible to corrosion and other external threats that can lead to pipe failure. One of the main external factors that ductile iron pipes need protection from is corrosion. Corrosion can occur due to the presence of certain chemicals in soil or water, and it can weaken the pipe over time. To protect against corrosion, ductile iron pipes are often coated with an external protective layer such as polyethylene or zinc. This coating acts as a barrier between the pipe and the corrosive elements, extending the lifespan of the pipe. In addition to corrosion, ductile iron pipes may also require protection against physical damage. These pipes are typically buried underground, making them vulnerable to external forces such as heavy machinery, ground movement, or even vandalism. To safeguard against physical damage, ductile iron pipes can be encased in concrete or surrounded by a protective sleeve or casing. Furthermore, ductile iron pipes may need protection against soil conditions that could potentially cause pipe movement or shifting. In areas with unstable soil, additional measures such as proper bedding and backfilling techniques, as well as the use of anchoring devices, may be necessary to ensure the stability and integrity of the pipes. In summary, while ductile iron pipes are robust, they still require additional protection against external factors. This can include corrosion protection, physical damage prevention, and measures to address soil conditions. By implementing these protective measures, the lifespan and performance of ductile iron pipes can be significantly extended, ensuring the reliable conveyance of water and other fluids.
