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.

Because of the special sealing structure design of the rubber sealing ring and the clamp hoop, the groove connecting piece has good sealing property, and the sealing property is enhanced correspondingly with the increase of the fluid pressure in the pipe.
- Q: How do ductile iron pipes handle water velocity?
- Due to their unique mechanical properties, ductile iron pipes are well-suited for managing water velocity. Ductile iron, being a highly durable and strong material, can endure high water velocities without significant damage or deformation. The inherent ductility of the pipe enables it to absorb the energy generated by the flowing water, effectively reducing the risk of pipe failure or bursting. This characteristic makes ductile iron pipes suitable for handling high-pressure water flow, making them an ideal choice in situations where water velocity is a concern. Furthermore, the smooth internal surface of ductile iron pipes promotes efficient water flow and minimizes friction losses. This smoothness reduces resistance encountered by the water as it moves through the pipe, allowing for higher water velocities without compromising the pipe's integrity. Moreover, ductile iron pipes can be manufactured in various sizes and thicknesses, providing customization options based on specific water velocity requirements.
