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:How are ductile iron pipes restrained against axial thrust forces?: Axial thrust forces are effectively restrained in ductile iron pipes by utilizing both mechanical restraints and soil resistance. A commonly employed method involves the use of thrust blocks, which are concrete structures constructed at bends, tees, and other directional changes in the pipeline. These blocks are specifically designed to withstand axial forces and prevent any shifting or movement of the pipes caused by the pressure exerted by the flowing fluid. Furthermore, additional support and prevention of axial movement are achieved through the implementation of mechanical restraints, such as pipe restraints, thrust collars, and anchor blocks. Pipe restraints are devices installed around the pipe and connected to adjacent structures, such as walls or concrete collars, in order to prevent any sort of movement. Thrust collars, on the other hand, are utilized to absorb and distribute the thrust forces generated by the flowing fluid. These collars, typically made of ductile iron or steel, are securely fastened around the pipe to counteract axial movement. Moreover, soil resistance plays a crucial role in restraining axial thrust forces. The weight of the soil surrounding the pipe creates frictional resistance, which effectively counteracts the axial forces. In order to ensure effective soil resistance, it is vital to properly backfill the trench, compact the soil, and adequately embed the pipe in the soil. In conclusion, a comprehensive approach involving the use of mechanical restraints such as thrust blocks, pipe restraints, and thrust collars, along with the soil resistance provided by proper trench backfilling and compaction, is employed to restrain axial thrust forces in ductile iron pipes. This approach guarantees the secure placement of the pipes and their ability to withstand the axial forces exerted by the flowing fluid.

Q:Why does the cast iron pipe always run off when testing?: The pipeline is installed, straight section of each pipe will be added pier, concrete pipe, elbow, three links should also have concrete pier, specific installation method according to GB Atlas 03SS515, and the straight pipe to soil, pipeline interface will be exposed, easy to check.

Q:QT400-10 nodular cast iron requires hardness of HRC47~51. Why can't quench hardness be reached?: QT400-10 shall ensure sufficient pearlite in the casting state, at least half of the pearlite. This is done with the temperature, time, and water. But if it is big, the heart hardness will not go up.

Q:What are the different sizes available for ductile iron pipe?: Ductile iron pipes are available in a wide range of sizes to cater to various applications in the water and wastewater industry. The sizes of ductile iron pipes typically range from 3 inches to 64 inches in diameter. The most commonly used sizes include 4 inches, 6 inches, 8 inches, 10 inches, 12 inches, 16 inches, 20 inches, 24 inches, 30 inches, and 36 inches. However, ductile iron pipes can also be manufactured in larger sizes depending on specific project requirements. These different sizes allow for flexibility in designing and constructing water distribution systems, sewage networks, and other infrastructure projects. The selection of the appropriate size depends on factors such as the volume of flow, pressure requirements, and the distance the pipe needs to cover. It is worth mentioning that the size of a ductile iron pipe refers to its internal diameter, also known as the nominal bore. The actual outside diameter of the pipe may vary slightly depending on the manufacturer and the specific dimensions provided. When choosing a size for ductile iron pipes, it is essential to consider factors such as hydraulic capacity, installation requirements, and the compatibility with other pipeline components. Consulting with engineers and industry experts is advisable to ensure the correct size selection for each specific application.

Q:How long does the cast iron pipe of indoor direct buried sewage need to be examined?: UPVC, also called hard PVC, is an amorphous thermoplastic resin made by polymerization of vinyl chloride monomer, with certain additives (such as stabilizers, lubricants, fillers, etc.). In addition to additives, the method of blending with other resins is also applied to make it have obvious practical value. These resins are CPVC, PE, ABS, EVA, MBS and so on. UPVC has high melt viscosity and poor flowability. Even if the pressure and melt temperature are increased, the fluidity is not changed. In addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the molding temperature range is very narrow. It is a difficult material to be formed.

Q:How are ductile iron pipes installed?: Ductile iron pipes are typically installed using a variety of methods, including trenching or open-cut excavation, horizontal directional drilling, and pipe bursting. In the traditional trenching method, a trench is dug to the required depth and slope, and the pipe is then lowered into place and joined using mechanical or push-on joints. Horizontal directional drilling involves drilling a pilot hole and then pulling the pipe through it, while pipe bursting involves breaking the existing pipe and replacing it with a new ductile iron pipe.

Q:Can ductile iron pipes be used for geothermal systems?: Yes, ductile iron pipes can be used for geothermal systems. Ductile iron pipes have excellent strength and durability, making them suitable for handling the high temperatures and pressures typically encountered in geothermal systems. Their corrosion resistance and flexibility also make them a reliable choice for transporting geothermal fluid efficiently.

Q:What are the different methods for cutting ductile iron pipe?: There are several different methods for cutting ductile iron pipe, depending on the specific requirements and constraints of the project. Some common methods include: 1. Manual Cutting: This method involves using a handheld saw or grinder with an abrasive cutting wheel to cut through the ductile iron pipe. It is a simple and relatively inexpensive method, but it can be labor-intensive and time-consuming for larger pipe sizes. 2. Mechanical Cutting: Mechanical cutting methods involve using specialized machinery to cut through the ductile iron pipe. This can include bandsaws, pipe cutters, or hydraulic cutting machines. These machines can provide faster and more precise cuts, especially for larger pipe sizes. However, they can be more expensive and require skilled operators. 3. Torch Cutting: Torch cutting, also known as oxyfuel cutting, involves using a torch to heat the ductile iron pipe and then introducing a high-pressure oxygen stream to create a chemical reaction that cuts through the metal. This method is effective for cutting thick-walled ductile iron pipe, but it can generate a significant amount of heat and sparks, requiring proper safety precautions. 4. Plasma Arc Cutting: Plasma arc cutting utilizes a high-velocity jet of ionized gas (plasma) to melt and cut through the ductile iron pipe. This method is ideal for cutting through thick-walled pipes where precision and efficiency are required. However, it can be more expensive and may require specialized equipment and training. 5. Waterjet Cutting: Waterjet cutting uses a high-pressure jet of water mixed with an abrasive material to cut through the ductile iron pipe. This method is highly precise and does not generate heat or sparks, making it suitable for cutting in sensitive environments. However, it can be slower and more expensive compared to other cutting methods. It is important to consider factors such as pipe size, project requirements, budget, and safety when selecting the appropriate method for cutting ductile iron pipe. Consulting with professionals or experts in the field can help determine the most suitable method for a specific project.
