Q: QT400-10 nodular cast iron requires hardness of HRC47~51. Why can't quench hardness be reached?: Quenching temperature: when the silicon content of nodular cast iron is 2.0-3.0%, the quenching temperature is 860-900 DEG C, the silicon content is low, and the upper limit is taken when the lower limit is high.2. holding time: because of the consideration of diffusion graphite cast iron, alloy steel is therefore the holding time, holding time longer than carbon steel.3. oil quenching.

Q: Can ductile iron pipe be used for water treatment plants?: Yes, ductile iron pipe can be used for water treatment plants. Ductile iron pipes are known for their strength, durability, and corrosion resistance, making them suitable for transporting water and other fluids in various industrial applications, including water treatment plants.

Q: Are ductile iron pipes suitable for gravity sewer systems?: Yes, ductile iron pipes are suitable for gravity sewer systems. Ductile iron pipes have several properties that make them well-suited for this application. Firstly, ductile iron pipes have high tensile strength, which means they can withstand the weight of the soil and other loads placed on them in a gravity sewer system. This strength allows the pipes to resist deformation and maintain their structural integrity over time. Additionally, ductile iron pipes have excellent corrosion resistance. This is important in sewer systems as they are often exposed to harsh and corrosive environments. The corrosion resistance of ductile iron pipes ensures their long-term durability and reduces the need for maintenance and repairs. Furthermore, ductile iron pipes have a smooth internal surface, which allows for efficient flow of wastewater in gravity sewer systems. The smooth surface minimizes friction and prevents the accumulation of debris and sediment, reducing the risk of blockages and improving the overall performance of the system. Moreover, ductile iron pipes are highly resistant to damage from external forces such as ground movements or heavy traffic. This makes them a reliable choice for gravity sewer systems, where the pipes may be subjected to various external stresses. Overall, the combination of high tensile strength, corrosion resistance, smooth internal surface, and resistance to external forces makes ductile iron pipes a suitable and reliable choice for gravity sewer systems.

Q: Can ductile iron pipe be used for industrial process piping?: Indeed, industrial process piping can make use of ductile iron pipe. Renowned for its robustness, longevity, and ability to withstand corrosion, ductile iron pipe proves itself as an appropriate selection for diverse industrial functions. It boasts the capability to manage high-pressure systems and commonly finds application in sectors like water and wastewater treatment, oil and gas, chemical processing, and power generation. Moreover, ductile iron pipe offers ease of installation and an extensive lifespan, thus rendering it a cost-efficient choice for industrial process piping.

Q: Are ductile iron pipes available in different wall thicknesses?: Yes, ductile iron pipes are available in different wall thicknesses to accommodate various applications and requirements.

Q: Can ductile iron pipes be used in oil or gas transmission pipelines?: Ductile iron pipes are applicable for oil or gas transmission pipelines. They belong to the cast iron category and possess enhanced characteristics, including increased tensile strength and ductility. These properties make them suitable for various applications, including pipeline systems used in oil and gas transmission. The corrosion resistance of ductile iron pipes is exceptional, which is crucial for pipelines that transport oil or gas over long distances. This material exhibits a high resistance to external factors such as soil chemicals, moisture, and corrosive gases commonly found in the oil and gas industry. Moreover, ductile iron pipes can endure high pressures and temperatures, making them suitable for the demanding requirements of oil and gas transmission. Moreover, ductile iron pipes have excellent impact resistance, enabling them to absorb and withstand external forces such as ground movement or heavy loads. This durability ensures the integrity and longevity of the pipeline system, minimizing the risk of leaks or failures. In summary, ductile iron pipes provide a reliable and cost-effective solution for oil and gas transmission pipelines. Their robustness, corrosion resistance, and ability to withstand high pressures and temperatures make them a viable choice for this critical infrastructure.

Q: How much is the installation cost of the ductile iron tube?: Water supply pipe is the first choice, with high cost performance. Compared with the PE pipe, from the installation time, ductile pipe PE pipe installation is simple and rapid, and after the installation of internal and external pressure bearing better tightness and corrosion resistance; from the point of view, ductile pipe sealing better after installation, but also can improve the corrosion resistance through various anti-corrosion methods;

Q: What is the expected external protection system for ductile iron pipes?: The expected external protection system for ductile iron pipes typically includes a combination of coatings and cathodic protection. Coatings, such as fusion-bonded epoxy (FBE) or polyethylene, are applied to the external surface of the pipe to provide a barrier against corrosion and protect it from the surrounding environment. These coatings are highly resistant to moisture, chemicals, and abrasion, ensuring the longevity of the pipe. In addition to coatings, cathodic protection is often employed to further enhance the external protection of ductile iron pipes. Cathodic protection involves the use of sacrificial anodes or impressed current systems to create a protective electrical current that counteracts the corrosive effects on the pipe's surface. This technique helps prevent corrosion by ensuring that the ductile iron remains in a cathodic state, where it is less prone to degradation. The combination of coatings and cathodic protection provides a robust and comprehensive external protection system for ductile iron pipes. These measures effectively safeguard the pipes from corrosion, extending their service life and minimizing the need for costly repairs or replacements. Regular inspection and maintenance are also essential to ensure the ongoing effectiveness of the external protection system and to address any potential issues promptly.

Q: Can ductile iron pipes be repaired if they get damaged?: Yes, ductile iron pipes can be repaired if they get damaged. The repair process involves identifying the damaged portion of the pipe and assessing the severity of the damage. If the damage is minor, it can be repaired using various techniques such as welding or epoxy lining. For more extensive damage, sections of the pipe may need to be replaced. Pipe repair professionals have the expertise and equipment to identify and fix damaged ductile iron pipes, ensuring their continued functionality and longevity.

Q: Can ductile iron pipe be used for underground applications?: Indeed, underground applications can employ ductile iron pipe. Renowned for its robustness and endurance, ductile iron pipe proves to be well-suited for a multitude of underground uses, including water and sewage systems, gas pipelines, and irrigation systems. Its exceptional resistance to corrosion and external burdens renders it a dependable selection for underground installations, where sustained functionality and structural soundness are pivotal considerations. Moreover, ductile iron pipe's pliability enables it to endure ground shifting and settling sans fracturing or shattering, making it an apt choice for regions susceptible to seismic occurrences.
