Q: Can ductile iron pipes be used in areas with high soil acidity?: Yes, ductile iron pipes can be used in areas with high soil acidity. Ductile iron is highly resistant to corrosion, including the effects of soil acidity, making it a suitable choice for such environments.

Q: An urban infrastructure construction, water supply pipe is ductile iron pipe and PE pipe, thank you: From the tightness and corrosion resistance, ductile pipe sealing better after installation, but also can improve the corrosion resistance of corrosion protection through a variety of means; from the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve more runoff large; from the installation and maintenance cost, ductile pipe have more favorable price.

Q: What is the exterior anticorrosion of nodular cast iron pipes?: First clean the impurity on the surface of the pipe or fitting, and then sprayed zinc treatment (130g/m and asphalt paint coating fand) not less than 70 m

Q: How are leaks repaired in ductile iron pipe?: Leaks in ductile iron pipe are typically repaired by cleaning and preparing the area around the leak, applying a suitable sealant or epoxy, and then securely fastening a repair clamp over the affected area. This clamp provides a tight seal and prevents any further leakage.

Q: What's the function of the cement mortar lining of ductile iron pipes?: You may easily say that this statement is vague and there is no evidence that other manufacturers often do so when promoting other types of lining. However, in order to prove the truth of the above view, we have compiled sufficient examples to demonstrate the reliability of each of these statements from a scientific and logical point of view.We have stated each of these fields and other embedded systems as specious statements. There is only a reasonable conclusion that the cement mortar lining (CML) provides excellent protection for ductile iron pipes and steel tubes.Ductile iron pipe and steel pipe CML CML produces a synergistic effect of the incomparable.

Q: How is ductile iron pipe recycled?: Ductile iron pipe, a material known for its durability, is commonly used in infrastructure systems like water and wastewater pipelines. Rather than being disposed of in landfills, ductile iron pipe can be recycled when it reaches the end of its life cycle. The recycling process for ductile iron pipe begins by removing it from the ground. Typically, a trench is dug to access the pipe, which is then cut into smaller, manageable sections using specialized equipment. These sections are then transported to a recycling facility. At the recycling facility, the ductile iron pipe undergoes further processing to eliminate any contaminants. This involves removing any fittings or joints that may be attached to the pipe. Additionally, non-iron materials like rubber gaskets or coatings are separated and discarded. Once the pipe has been cleaned and prepared, it is usually crushed or shredded into smaller pieces. This increases the material's surface area, making it easier to melt down in the next stage of the recycling process. The crushed or shredded ductile iron pipe is then melted in a furnace at high temperatures, a process called smelting. Smelting converts the solid iron into a liquid state. During this process, impurities and any remaining non-iron materials rise to the surface and are removed. After smelting, the molten iron is poured into molds to create new products. These molds can produce various ductile iron products, including new pipes, fittings, valves, and manhole covers. The recycled ductile iron products possess the same qualities and durability as those made from virgin materials. Recycling ductile iron pipe not only reduces the need for new materials but also conserves energy and resources. The recycling process requires less energy compared to producing iron from raw materials, resulting in a lower carbon footprint. Furthermore, recycling ductile iron pipe helps minimize waste and promotes a circular economy by giving new life to a previously discarded material.

Q: What are the interface forms of ductile iron pipes? The best drawings are available. Thank you: T interface type sealing ring is a self sealing rubber ring, when the pipe internal pressure increases, the contact pressure between the seal and the pipe increases, T interface can not only allow the deflection angle of the axial displacement, and convenient for installation. When the T type interface is installed, the sealing of the rubber ring can be ensured as long as the socket is simply loaded into the socket and the rubber ring is pressed tightly. This kind of interface has the advantages of reliable sealing, good seismic resistance and corrosion resistance, and it is a better interface.

Q: Can ductile iron pipes be used for river crossings?: Ductile iron pipes are suitable for river crossings. With their strength and durability, they can endure the pressure and stress of being buried and crossed by a river. Ductile iron is widely used in water and sewage systems, proving its reliability for river crossings. Nevertheless, it is crucial to account for additional factors like river depth, pipe size and weight, and the installation procedure. This guarantees the appropriate design and installation of ductile iron pipes for river crossings.

Q: What is the DN400 installation charge for ductile iron pipes?: The wages paid under special circumstances: refers to the provisions of the state laws, regulations and policies, due to illness, injury, maternity leave, family planning leave, funeral leave, leave, leave, leave, regular shutdown, implementation of national or social obligations due to pay a certain percentage of wage hourly wage or salary when.
