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: How are ductile iron pipes protected against external soil loads?
- Ductile iron pipes are protected against external soil loads through a combination of proper installation techniques and the use of protective coatings. The pipes are installed in a manner that allows for adequate support and backfilling, which helps distribute the external soil loads evenly. Additionally, these pipes are often coated with materials such as epoxy or polyethylene to provide a barrier between the pipe and the surrounding soil, preventing corrosion and damage from external forces. This protective coating ensures the longevity and durability of ductile iron pipes in underground applications.
- Q: What is the expected fire resistance of ductile iron pipes?
- The expected fire resistance of ductile iron pipes can vary depending on several factors such as the thickness of the pipe walls, the quality of the installation, and the surrounding conditions. However, generally speaking, ductile iron pipes have a high fire resistance due to their durable and heat-resistant material composition. Ductile iron is made by adding a small amount of magnesium to cast iron, which enhances its strength and flexibility. This makes ductile iron pipes less susceptible to cracking or breaking under high temperatures compared to other materials like PVC or HDPE pipes. In terms of fire resistance, ductile iron pipes can withstand high temperatures for an extended period of time without significant structural damage. They have been tested and proven to maintain their integrity in fire conditions for up to 2-4 hours, depending on the specific pipe design and installation. It is important to note that while ductile iron pipes have a high fire resistance, they are not fireproof. In case of a fire, it is crucial to follow proper fire safety protocols and consult with professionals to ensure the safety of the system and surrounding infrastructure.
