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: What is the expected burst pressure of ductile iron pipes?: The expected burst pressure of ductile iron pipes can vary depending on various factors such as the pipe diameter, wall thickness, and the specific grade of ductile iron used. However, in general, ductile iron pipes typically have a burst pressure ranging from 350 to 700 psi (pounds per square inch).

Q: Can ductile iron pipes be used for industrial applications?: Yes, industrial applications can utilize ductile iron pipes. Ductile iron, a form of cast iron, possesses enhanced mechanical characteristics compared to traditional cast iron. These improvements include increased ductility and strength. Consequently, ductile iron pipes are highly appropriate for industrial applications that require durability, strength, and resistance to external forces. Industrial applications often necessitate the transportation of high-pressure water or fluids. Ductile iron pipes are specifically designed to endure such circumstances. Their exceptional tensile strength enables them to withstand deformation and fractures. This quality renders them optimal for managing heavy loads and enduring significant internal and external pressures. Moreover, ductile iron pipes exhibit exceptional resistance to corrosion, rendering them remarkably suitable for industrial applications that entail exposure to harsh chemicals or corrosive substances. The pipes' resistance to corrosion ensures a prolonged lifespan and decreases maintenance expenses associated with pipe replacements or repairs. Furthermore, ductile iron pipes are renowned for their adaptability and versatility.

To maintain the longevity and efficiency of the underground compressed air system, regular maintenance and inspection should also be carried out.

Q: What is the content of silicon in silicon molybdenum ductile iron?: Silicon molybdenum material, similar to the United States IDM5381, 5402 and other brands, engaged in automotive components (such as turbocharger parts), and other heat resistant parts have been exposed to high temperature

Q: How do ductile iron pipes handle concentrated loads?: Ductile iron pipes are specifically designed to handle concentrated loads effectively. Due to their unique composition and manufacturing process, they possess excellent strength and durability, making them highly resistant to cracking or breaking under heavy loads. One of the key characteristics of ductile iron pipes is their high tensile strength, which enables them to withstand concentrated loads without deformation. The pipes are made by adding small amounts of magnesium to cast iron during the production process, which transforms the brittle graphite flakes into nodular graphite. This modification significantly enhances the material's strength and ductility, allowing it to handle concentrated loads more effectively. Additionally, ductile iron pipes have a high modulus of elasticity, meaning they can deform elastically under a load and then return to their original shape once the load is removed. This property enables the pipes to distribute the concentrated load evenly along their entire length, minimizing stress concentrations and reducing the risk of fractures or failures. Furthermore, ductile iron pipes have a thick, robust wall thickness, providing them with exceptional structural integrity. This thickness allows the pipes to bear significant loads and withstand pressure variations without compromising their overall performance. In summary, ductile iron pipes are specifically engineered to handle concentrated loads due to their high tensile strength, elastic deformation capabilities, and thick wall thickness. These characteristics make them a reliable choice for various applications, including water and wastewater systems, as they can withstand significant external forces without compromising their structural integrity.
