5.FAQ:
We have organized several common questions for our clients，may help you sincerely：
1.Q: Why would you choose ductile iron pipe rather than other pipe materials?
A:The reasons are obvious for that not only ductile iron pipe possesses the inherent strength and flexibility of ductile iron, combined with proven corrosion protection systems, but also the cost savings can be achieved from design to installation and commissioning.
2.Q:Why can you guarantee the inner of pipes can’t be corroded?
A: High alumina cement mortar lining and sulphate-resistant cement mortar lining. These two special linings are applicable to inner anti-corrosion for sewage pipes, improving resistance to erosion of the sewage components.

Q:How does the white iron appear in the case of ductile iron?: If it is to solve the white cast, the casting can be annealed.To prevent a chill in the casting, it is important to know your entire casting process to find the cause and the solution.

Q:What is the external coating used in ductile iron pipes?: The external coating used in ductile iron pipes is typically made of a protective material such as zinc or asphalt. These coatings are applied to the surface of the pipe to provide corrosion resistance and protect the iron from the surrounding environment. Zinc coatings, such as hot-dip galvanizing, are commonly used due to their excellent corrosion resistance properties. Asphalt coatings, on the other hand, provide a durable and flexible barrier against corrosion and abrasion. The choice of coating depends on factors such as the intended application, environmental conditions, and the specific requirements of the project.

Q:Can ductile iron pipes be used for underground cooling water systems?: Yes, ductile iron pipes can be used for underground cooling water systems. Ductile iron is known for its strength, durability, and corrosion resistance, making it suitable for various applications, including underground installations. It can withstand the pressure and temperature requirements of cooling water systems, providing a reliable and long-lasting solution.

Q:What are the recommended bedding and backfill materials for ductile iron pipe?: The recommended bedding and backfill materials for ductile iron pipe typically include a layer of granular material, such as sand or pea gravel, for bedding and a layer of compacted soil or select backfill material for backfilling. This helps to distribute load and protect the pipe from external forces while maintaining stability and preventing damage.

Q:What is the maximum operating pressure for ductile iron pipes?: The maximum operating pressure of ductile iron pipes may vary based on factors like pipe diameter, wall thickness, and the specific usage. Nonetheless, typically, ductile iron pipes are engineered to endure pressures of up to 350 psi (pounds per square inch), and occasionally even higher. It is worth highlighting that to ascertain the precise maximum operating pressure for a specific ductile iron pipe system, one should refer to local regulations, engineering standards, and manufacturer specifications.

Q:How does ductile iron pipe perform in corrosive soils?: Due to its inherent corrosion resistance properties, ductile iron pipe demonstrates exceptional performance in corrosive soils. This is attributed to its unique composition of iron, carbon, and other elements that enhance its durability and resistance to corrosion. A key feature of ductile iron pipe is its protective lining, which is either cement mortar or a special epoxy coating. This lining acts as a barrier between the corrosive soil and the pipe, preventing direct contact and corrosion. Furthermore, compared to other materials like steel, ductile iron pipe exhibits higher resistance to external corrosion. It can withstand the chemical reactions caused by acidic or alkaline soils and remains unaffected by the corrosive elements present in the ground. This quality makes it an ideal choice for installation in highly corrosive soil areas. Moreover, ductile iron pipe has a long service life, further contributing to its performance in corrosive soils. Its durability and resistance to corrosion ensure that it can withstand the challenges posed by corrosive soils for several decades without significant degradation. In conclusion, ductile iron pipe excels in corrosive soils due to its protective lining, resistance to external corrosion, and long service life. Its ability to withstand the harsh conditions presented by corrosive soils makes it a reliable and durable choice for various applications such as water distribution, sewage systems, and industrial pipelines.

Q:Can ductile iron pipe be used for oil and gas pipelines?: Yes, ductile iron pipe can be used for oil and gas pipelines. Its high strength, durability, and corrosion resistance make it suitable for transporting oil and gas over long distances. Additionally, its flexibility and ability to withstand high pressures and temperatures make it a reliable choice for such applications.

Q:What are the typical applications for ductile iron pipes?: Ductile iron pipes are commonly used in various applications due to their unique properties and advantages. Some of the typical applications for ductile iron pipes include: 1.

These pipes are commonly used in underground sewer lines, sewer force mains, and wastewater treatment plants. 3. Industrial Applications: Ductile iron pipes find applications in various industrial sectors. They are commonly used for transporting different types of fluids, such as chemicals, slurries, and abrasive substances. Their strength, toughness, and resistance to external loads make them suitable for industrial pipelines, including those in power plants, refineries, and mining operations. 4. Irrigation Systems: Ductile iron pipes are frequently employed in irrigation systems for agriculture, landscaping, and golf courses. These pipes can withstand high water pressure and provide a reliable solution for transporting water over long distances. Their corrosion resistance ensures water quality is maintained, and their durability reduces the need for frequent maintenance. 5. Fire Protection Systems: Ductile iron pipes are widely used in fire protection systems, including sprinkler systems and fire hydrants. Their strength and ability to withstand high pressure make them suitable for delivering water rapidly in case of fire emergencies. These pipes are also resistant to heat, making them a reliable choice for fire protection applications. In summary, ductile iron pipes are versatile and widely used in various applications, including water supply systems, wastewater and sewage systems, industrial pipelines, irrigation systems, and fire protection systems. Their durability, corrosion resistance, and ability to withstand high pressure make them a preferred choice for these applications.

Q:Does the cast iron pipe for spheroidal graphite need corrosion protection when laying underground?: Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..

Q:Can ductile iron pipes be used for gravity sewer systems?: Certainly! Gravity sewer systems can utilize ductile iron pipes. Ductile iron pipes boast durability, strength, and corrosion resistance, making them appropriate for a range of purposes, such as sewer systems. These pipes possess remarkable tensile strength and can endure substantial pressure and heavy loads, which renders them well-suited for gravity sewer systems where wastewater naturally flows rather than requiring pumping. Moreover, ductile iron pipes boast an extended lifespan and necessitate minimal maintenance, thus proving to be a cost-efficient option for sewer infrastructure.
