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 pipe be used for potable water systems?
- Yes, ductile iron pipe can be used for potable water systems. Ductile iron is a type of cast iron that is known for its strength, durability, and ability to withstand high pressure. It is also corrosion-resistant, making it suitable for use in water distribution systems. Ductile iron pipe is commonly used in potable water systems due to its longevity and low maintenance requirements. Additionally, it is approved by various standards organizations, such as the American Water Works Association (AWWA), for use in potable water applications. However, it is important to ensure that the ductile iron pipe used for potable water systems is manufactured and installed according to the appropriate standards and regulations to ensure the safety and quality of the water supply.
- Q: Can ductile iron pipes be used for agricultural applications?
- Certainly, agricultural applications can make use of ductile iron pipes.

- Q: What are the different lining thickness options for ductile iron pipe?
- The specific application and project requirements typically dictate the various options for lining thickness in ductile iron pipes. Cement mortar lining, polyurethane lining, and polyethylene lining are among the most commonly used options. Cement mortar lining, which is widely employed in ductile iron pipes, involves the application of a layer of cement mortar on the inner surface of the pipe. This lining provides corrosion protection and enhances the hydraulic performance of the pipe. The thickness of cement mortar lining can vary from 3mm to 6mm. Polyurethane lining, another popular choice, is particularly suitable for applications requiring resistance to abrasion and chemical attack. It is usually applied using a spray or casting method, and the thickness can vary depending on project specifications. Typically, polyurethane linings range from 1mm to 4mm in thickness. Polyethylene lining, a relatively newer technology, is commonly used in applications where chemical corrosion resistance is crucial. The lining is applied using a rotational lining process, wherein a layer of molten polyethylene is evenly distributed on the internal surface of the pipe. The thickness of polyethylene lining can range from 2mm to 8mm, depending on project requirements. It is worth noting that the lining thickness can be tailored to meet specific project needs, including the corrosiveness of the transported fluid, operating conditions, and desired service life of the pipe. Consulting with a qualified engineer or pipe manufacturer is advisable to determine the most suitable lining thickness for a given application.
