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: Do ductile iron pipes require cathodic protection?: Yes, ductile iron pipes require cathodic protection. Cathodic protection is a technique used to protect metallic structures from corrosion by making them the cathode of an electrochemical cell. Ductile iron pipes are susceptible to corrosion, especially in aggressive soil conditions or when in contact with water containing high levels of corrosive substances such as chlorides or sulfates. Cathodic protection helps prevent corrosion by applying a direct electrical current to the pipe, which counteracts the natural corrosion process. This method ensures the longevity and integrity of the ductile iron pipes, reducing the need for frequent repairs or replacements.

Q: Are ductile iron pipes suitable for use in cooling water systems?: Ductile iron pipes are indeed appropriate for utilization in cooling water systems. They exhibit remarkable strength and durability, rendering them impervious to the intense pressure and corrosive properties inherent in such systems. Furthermore, they possess the ability to withstand extreme fluctuations in temperature while delivering enduring performance. Additionally, ductile iron pipes exhibit commendable resistance to the proliferation of microorganisms, a crucial aspect in preserving the quality of the cooling water. Moreover, these pipes facilitate effortless installation and necessitate minimal maintenance, thereby constituting a cost-effective alternative for cooling water systems. In summary, ductile iron pipes represent a dependable and suitable choice for employment in cooling water systems.

Q: Can ductile iron pipes be used for underground sewage systems?: Underground sewage systems can utilize ductile iron pipes, which offer numerous advantages. Ductile iron is a form of cast iron that possesses improved flexibility and strength, making it suitable for a variety of applications, including sewage systems. The first advantage of ductile iron pipes for underground sewage systems is their exceptional resistance to corrosion. This is particularly important in sewage systems where moisture and chemicals can contribute to corrosion over time. By resisting corrosion, these pipes ensure long-term durability and reliability. Additionally, ductile iron pipes possess high tensile strength, enabling them to withstand the pressure and stress that occur in underground sewage systems. They are also capable of withstanding ground movements, such as soil settling or shifting, which can cause damage to pipes made from other materials.

Q: What are the different types of valves available for ductile iron pipe?: There are several different types of valves available for ductile iron pipe, each serving a specific purpose and function. Some of the most common types of valves used with ductile iron pipe include: 1. Gate Valves: These valves are used to either completely open or close the flow of fluid within the pipe. They have a gate-like mechanism that either blocks or allows the passage of fluid when the valve is either fully open or fully closed. 2. Butterfly Valves: Butterfly valves are quarter-turn valves that use a circular disc as the closing mechanism. When the valve is open, the disc is parallel to the flow, allowing for minimal pressure drop. When the valve is closed, the disc is perpendicular to the flow, completely stopping the fluid. 3. Ball Valves: Ball valves have a spherical disc with a hole in the middle, known as a ball. When the valve is open, the ball is positioned in such a way that it allows fluid to flow through the hole. When the valve is closed, the ball is rotated to block the flow. 4. Check Valves: Check valves are designed to allow fluid to flow in one direction only, preventing backflow. They have a flap or a disc that opens when the flow is in the correct direction, and closes to stop the flow when it tries to reverse. 5. Plug Valves: Plug valves have a cylindrical or conical plug with a hole through it that can be rotated to control the flow. When the valve is open, the hole aligns with the pipe, allowing fluid to pass through. When the valve is closed, the hole is perpendicular to the pipe, blocking the flow. 6. Pressure Reducing Valves: These valves are used to control and reduce the pressure of fluid flowing through the pipe. They have a mechanism that adjusts the flow area, allowing for pressure reduction. 7. Pressure Sustaining Valves: Pressure sustaining valves are used to maintain a specific pressure within the pipe. They automatically adjust the flow area to sustain the desired pressure level. 8. Air Release Valves: Air release valves are used to release air trapped within the pipe. They allow air to escape while preventing fluid from leaking out. These are just a few examples of the different types of valves available for ductile iron pipe. The choice of valve depends on the specific application, flow requirements, and desired functionality.
