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 are the typical surge anticipation measures for ductile iron pipe?
To mitigate potential damage caused by surges or water hammer in ductile iron pipe systems, various techniques can be employed. These measures aim to absorb or redirect sudden pressure changes, preventing pipe rupture or failure. Common surge anticipation measures for ductile iron pipe include: 1. Incorporating air chambers strategically along the pipeline to create a cushion of air that absorbs surge energy. As the pressure wave travels through the pipe, the air compresses, reducing the impact on the pipe and minimizing the risk of damage. 2. Connecting surge tanks, which act as storage reservoirs for excess pressure, to the pipeline. When a surge occurs, the surge tank absorbs the excess water volume, preventing damage to the pipe. The stored water is gradually released back into the system, stabilizing the pressure. 3. Installing surge relief valves in the pipeline to automatically release excess pressure during surge events. These valves open when the pressure exceeds a preset limit, allowing the surge to dissipate harmlessly. Surge relief valves can be adjusted to release the desired amount of pressure, ensuring the safety of the ductile iron pipe. 4. Utilizing water hammer arrestors, which are devices that absorb the shock generated by surges and water hammer. These devices consist of sealed chambers filled with a compressible gas or liquid that absorbs sudden pressure changes. By absorbing the energy, water hammer arrestors protect the ductile iron pipe from potential damage. 5. Using surge suppressors, devices that regulate the flow of water during surge events. Surge suppressors are designed to reduce the speed at which surges travel through the pipe, minimizing the impact on the system. These devices can be installed at critical points in the pipeline to prevent damage to the ductile iron pipe. To determine the most suitable surge anticipation measures for ductile iron pipe installations, it is important to consider the specific requirements of the pipeline system and consult experienced engineers or industry professionals.
