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.

Renowned for their strength, durability, and flexibility, ductile iron pipes are an excellent choice for such purposes. They possess the capability to endure heavy loads, resist corrosion, and handle high flow rates, thus establishing them as a dependable option for culverts and storm sewers. Moreover, their extended lifespan and low maintenance needs further contribute to their appropriateness in these applications. Furthermore, ductile iron pipes can be easily installed and are available in various sizes and configurations to suit the specific requirements of culvert or storm sewer projects. In summary, ductile iron pipes have been extensively employed and proven to be an efficient and long-lasting solution for culvert or storm sewer applications.

Q: Can ductile iron pipes be used for railway bridges?: Yes, ductile iron pipes can be used for railway bridges. They are commonly used in bridge construction due to their high strength, durability, and resistance to corrosion. Additionally, ductile iron pipes can withstand heavy loads and provide excellent structural support, making them suitable for railway bridge applications.

Q: How does ductile iron pipe perform in areas with high soil contamination?: Ductile iron pipe performs exceptionally well in areas with high soil contamination due to its inherent strength, durability, and corrosion resistance properties. The material used in manufacturing ductile iron pipes is highly resistant to chemical attack, making it suitable for handling various types of contaminated soils, including those with high levels of acids, alkalis, and other corrosive substances. The corrosion resistance of ductile iron pipes is primarily attributed to their protective internal and external linings, which are designed to prevent contact between the pipe material and the surrounding soil or fluids. These linings act as a barrier, preventing the penetration of corrosive elements and reducing the risk of pipe degradation or failure. Additionally, ductile iron pipes can be further protected by applying external coatings or cathodic protection systems, which enhance their resistance to soil contamination and extend their service life. In areas with high soil contamination, ductile iron pipes offer significant advantages over other materials such as steel or concrete. Their high strength allows them to withstand the external loads imposed by the contaminated soil, reducing the risk of structural failure or deformation. Moreover, the inherent flexibility of ductile iron allows it to absorb ground movements or settlement without compromising its integrity, making it a reliable choice for areas prone to soil instability or shifting. Furthermore, ductile iron pipes have a smooth internal surface, which minimizes friction and helps maintain efficient flow rates even in the presence of contaminants. This characteristic is particularly important in areas with high soil contamination, where debris or sedimentation can accumulate and hinder fluid flow. The smooth bore of ductile iron pipes reduces the risk of clogging and ensures the continuous and reliable conveyance of fluids, even in challenging soil conditions. Overall, ductile iron pipe is a highly suitable choice for areas with high soil contamination. Its excellent corrosion resistance, strength, flexibility, and smooth internal surface make it a reliable and durable solution for conveying fluids in these challenging environments.

Q: Can ductile iron pipes be used in areas with high levels of organic matter in soil?: Yes, ductile iron pipes can be used in areas with high levels of organic matter in soil.
