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: Can ductile iron pipes be used in areas with high soil acidity?
- To ensure the durability and performance of ductile iron pipes in areas with high soil acidity, certain precautions should be taken. Ductile iron pipes are renowned for their strength, durability, and resistance to corrosion, making them suitable for various soil conditions, including those with high acidity. However, the presence of high soil acidity can still pose a potential risk to ductile iron pipes over time. Acidic soils can accelerate the corrosion process, leading to the degradation of the pipe material. To mitigate this risk, the following measures can be implemented: 1. Protective Coatings: Applying protective coatings, such as epoxy or polyethylene, to the outer surface of the pipes adds an extra layer of defense against soil acidity. These coatings act as a barrier, preventing direct contact between the pipe and the corrosive soil. 2. pH Adjustment: Adjusting the pH levels of the soil can help reduce its acidity. This can be achieved by incorporating lime or other neutralizing agents into the soil, creating a more favorable environment for the ductile iron pipes. 3. Cathodic Protection: Employing cathodic protection systems is an effective method to prevent corrosion in ductile iron pipes. This technique involves utilizing sacrificial anodes or impressed current systems to generate a protective electrical current that counteracts the corrosive effects of the soil. 4. Regular Inspections: Conducting periodic inspections is crucial to monitor the condition of the ductile iron pipes in high soil acidity areas. This enables early detection of any corrosion or degradation, facilitating timely repairs or replacements. By implementing these measures, ductile iron pipes can be effectively utilized in areas with high soil acidity, guaranteeing long-term performance and minimizing the risks associated with corrosive soils. However, it is advisable to consult experts or engineers familiar with local soil conditions and project requirements to determine the most suitable materials and protective measures.

- Q: Are ductile iron pipes suitable for underground applications?
- Indeed, underground applications are well-suited for ductile iron pipes. Renowned for their durability, strength, and resistance to corrosion, these pipes emerge as an excellent option for installations that lie beneath the surface. Their ability to withstand immense loads, ground shifts, and external pressure further solidifies their appropriateness for burial underground. Moreover, given the challenges associated with access and maintenance in underground scenarios, the fact that ductile iron pipes boast a lifespan of over 100 years becomes invaluable. In conclusion, the reliability and suitability of ductile iron pipes for underground applications are underscored by their robustness and longevity.
- Q: Can ductile iron pipes be used for wastewater treatment plants?
- Indeed, ductile iron pipes have proven to be a viable option for wastewater treatment plants. Renowned for their robustness and endurance, these pipes are well-suited to endure the challenging and corrosive conditions present in such facilities. They possess the ability to withstand elevated pressures and exhibit resistance against corrosion, which is crucial for effectively managing wastewater and the diverse range of chemicals utilized in the treatment procedure. Additionally, ductile iron pipes offer the advantage of being effortless to install and maintain, ensuring an extended period of service. Consequently, they are frequently utilized in wastewater treatment plants for the transportation and distribution of wastewater across the entirety of the establishment.
- Q: What is the weight of a typical ductile iron pipe?
- The weight of a typical ductile iron pipe can vary depending on its size and wall thickness. Generally, ductile iron pipes are available in sizes ranging from 3 inches to 64 inches in diameter. The weight of these pipes can range from a few pounds per foot for smaller sizes to several hundred pounds per foot for larger diameters. Wall thickness also plays a significant role in determining the weight of the pipe. Thicker walls will result in a heavier pipe. For instance, a 10-inch ductile iron pipe with a wall thickness of 0.25 inches may weigh around 26 pounds per foot, whereas a 24-inch ductile iron pipe with a wall thickness of 0.5 inches can weigh approximately 175 pounds per foot. It is important to consult specific manufacturer specifications or engineering references to determine the precise weight of a particular ductile iron pipe.
