Q:Ductile cast iron can replace copper sleeve: Under dry friction conditions, we design a pre - formed synovial membrane on the surface of the bearing to ensure that the solid lubricant is transferred to the dual parts in the shortest possible time, and an effective solid lubricant film is formed

Q:Can ductile iron pipes be used in high-pressure applications?: Yes, ductile iron pipes can be used in high-pressure applications. Ductile iron has excellent mechanical properties and high tensile strength, making it suitable for withstanding high-pressure conditions. Its inherent toughness and durability allow it to handle the stress and pressure exerted on the pipes, making it a reliable choice for various high-pressure applications.

Q:Can ductile iron pipes be used for wastewater pumping stations?: Indeed, wastewater pumping stations can utilize ductile iron pipes. With their remarkable strength and durability, ductile iron pipes are well-suited for transporting wastewater and effectively managing the immense pressures and corrosive properties of sewage. Furthermore, the smooth interior surface of ductile iron pipes prevents blockages and facilitates the efficient flow of wastewater. Moreover, these pipes exhibit resistance towards external forces like soil displacement or heavy vehicular movement, thereby establishing themselves as a dependable option for wastewater pumping stations.

Q:Which is better, ductile iron pipe and spray plastic pipe?: Ductile iron pipe corrosion resistance, strength, it is said that the Ming Dynasty ordinary cast iron works now, and now has a new type of dedicated, can be used, construction becomes very convenient, ductile iron pipe has no effect on water quality. Plastic sprayed steel pipe is a new type of pipeline with higher price.

Q:What is the minimum operating temperature for ductile iron pipes?: The minimum operating temperature for ductile iron pipes is typically around -20 degrees Celsius (-4 degrees Fahrenheit).

Q:What's the difference between cast iron pipe and steel pipe?: Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.

Q:What is the relationship between continuous cast iron pipe and ductile iron pipe?: In general, the continuous cast iron pipe is the continuous casting of gray cast iron pipe, while the centrifugal cast iron pipe is centrifugal ductile iron pipe. Of course, you have to be hard, just to make continuous ductile iron pipes, that's what you want.

Q:Are ductile iron pipes suitable for installation in areas with high groundwater salinity?: Yes, ductile iron pipes are generally suitable for installation in areas with high groundwater salinity. Ductile iron is known for its corrosion resistance, making it a preferred choice in such environments. However, it is crucial to consider the specific salinity levels and consult with experts to ensure proper pipe coating and protection measures are in place to prevent any potential corrosion or degradation.

Q:How do ductile iron pipes handle ground movement in earthquake-prone areas?: In earthquake-prone areas, ductile iron pipes are highly regarded for their exceptional resistance to ground movement. These pipes are specifically designed to endure external forces, including seismic activities and shifting ground. The remarkable flexibility of ductile iron pipes allows them to effectively absorb and distribute the energy generated during ground movement. This flexibility is achieved through the unique composition of ductile iron, which contains nodular graphite in its microstructure. The presence of nodular graphite grants the pipe with ductility and resilience, enabling it to deform under stress without breaking. During an earthquake, when the ground begins to shift, ductile iron pipes have the capacity to adapt to the changing conditions. They can elongate, compress, and bend, thereby reducing the likelihood of pipe failure. This characteristic is of utmost importance in earthquake-prone areas, as it helps prevent catastrophic failures and water loss that may occur with more rigid pipe materials. Furthermore, ductile iron pipes possess a high level of joint integrity, further enhancing their ability to withstand ground movement during seismic events. The joints of these pipes are engineered to withstand lateral and angular movement, ensuring their integrity and preventing leaks. In addition to their inherent flexibility, ductile iron pipes are often installed using techniques that enhance their resistance to ground movement. Anchoring systems, such as thrust blocks and restraints, can be employed to secure the pipes and prevent excessive movement. These systems contribute to the stability of the pipeline network and further minimize the potential for damage during earthquakes. Overall, the combination of ductility, joint integrity, and anchoring systems make ductile iron pipes an exceedingly reliable choice for managing ground movement in earthquake-prone areas. They offer a durable and resilient solution that can withstand the challenges posed by seismic activities, guaranteeing a continuous water supply and minimizing the risk of infrastructure damage.

Q:What is the excavation width of ductile iron pipes with diameters greater than 1400?: When the condition does not allow enough slope, it is necessary to do wall protection and other means to ensure safetyRemind me, such a big pipe, dig deep in two ways. One is the depth diameter (range at the junction of 1.6 m in length and 500 for manholes and operation. The lower bolt assembly when) there is a depth diameter plus 500. and then in the trench laying branch the pier, installed after the fine stone tamped backfill.Can also be buried directly with the pipe diameter, and then put into the assembly. This method requires a large space on the ground, otherwise, the volume is too large after assembly, weight is too heavy, may cause damage to the pipeline and personnel injuries
