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: Can ductile iron pipes be used for irrigation canal lining?
- Yes, ductile iron pipes can be used for irrigation canal lining. Ductile iron pipes are known for their strength, durability, and resistance to external pressure and impact. These qualities make them suitable for use in irrigation canal lining, as they can withstand the harsh conditions of the environment such as high water pressure, soil movement, and exposure to chemicals and corrosive elements. Ductile iron pipes also have a smooth interior surface, which allows for efficient water flow and reduces the risk of clogging or sediment buildup. This is important for irrigation canals, as it ensures a continuous supply of water to the crops or plants being irrigated. Additionally, ductile iron pipes are highly resistant to damage from external factors such as roots, rocks, or other objects that may come into contact with the canal lining. This helps to minimize the risk of leaks or breaks in the irrigation system, ensuring a reliable and efficient irrigation process. It is worth noting that the selection of ductile iron pipes for irrigation canal lining should take into account factors such as the size and capacity of the canal, the water pressure requirements, and the specific conditions of the irrigation project. Consulting with a professional engineer or irrigation specialist can help determine the most suitable materials for the specific requirements of the project.
- Q: What is the lifespan of ductile iron pipe?
- The lifespan of ductile iron pipe can vary depending on several factors such as the quality of the pipe, installation conditions, and maintenance practices. On average, ductile iron pipe can last for 50 to 100 years or more, making it a durable and long-lasting option for water and wastewater infrastructure.
- Q: Principles for the antiseptic treatment of ductile iron pipes
- The principle that the antiseptic treatment of ductile iron pipes must be complied with is that.1. internal and external surface coating shall be kept clean, remove rust and impurities2. after coating on the inside and outside surface, the coating should be even and smooth, firm and firm, and shall not be abnormal because of climate change3. coating for water delivery should be insoluble in water, no peculiar smell, harmful impurities content
- Q: What are the common methods for flow control in ductile iron pipes?
- The common methods for flow control in ductile iron pipes include the use of valves, such as gate valves, butterfly valves, and check valves. These valves are designed to regulate the flow of water or other fluids in the pipe, allowing for control and adjustment of the flow rate. Additionally, flow control can also be achieved through the use of flow meters and flow regulators, which monitor and regulate the flow of fluids through the pipe system.
- Q: Which is better, ductile iron pipe and spray plastic pipe?
- Spray pipe is: plastic composite pipe, steel pipe is a new composite material as matrix, through a special process in high temperature curing by walls melt spraying or adsorption of food grade epoxy powder coating or PE as raw material. It has excellent corrosion resistance and relatively small frictional resistance.
- Q: What is the typical lifespan of ductile iron pipe?
- The typical lifespan of ductile iron pipe can vary depending on various factors such as the quality of the pipe, the conditions it is exposed to, and the maintenance practices employed. However, on average, ductile iron pipe has a lifespan of around 100 years. This is due to its inherent strength and durability, which allows it to withstand high pressure and various environmental conditions. Additionally, ductile iron pipe is often coated with protective materials such as cement mortar lining or polyethylene encasement, further enhancing its longevity. Regular inspections and maintenance can also help extend the lifespan of ductile iron pipe, ensuring that any issues or potential damages are identified and addressed promptly.
- Q: What is the disadvantage of nodular cast iron in excess of silicon?
- Silicon has a great influence on the performance of nodular cast iron. It mainly shows that silicon can refine graphite and improve the roundness of graphite ball.
- Q: How are ductile iron pipes tested for hydrostatic pressure?
- For water and wastewater applications, ductile iron pipes are widely used because of their strength and durability. To guarantee their quality and dependability, these pipes undergo hydrostatic pressure testing. The process of hydrostatic pressure testing involves applying internal pressure on the ductile iron pipes at levels higher than their normal operating pressure. This is done to evaluate their ability to withstand the maximum pressure they may encounter during their service life. To begin the testing, a sample set of pipes is carefully selected from a production batch or shipment. These samples are meticulously prepared by removing any surface coatings or debris that could affect the accuracy of the test results. The prepared samples are then placed in a specially designed test rig or test line. The test rig is equipped with all the necessary connections, valves, and gauges to accurately control and monitor the test conditions. Once the samples are secured in the test rig, water or another suitable test fluid is slowly introduced into the pipes. The pressure is gradually increased to a preset level, typically surpassing the expected operating pressure by a certain factor. This elevated pressure is maintained for a specified duration, usually several hours, to evaluate the structural integrity and leak resistance of the pipes. Throughout the test, the pipes are closely monitored for any signs of leakage, deformation, or failure. Skilled technicians or engineers observe the pressure gauges and visually inspect the pipes for any visible defects or abnormalities. Additionally, automated systems may be used to continuously record and analyze the pressure readings, ensuring accurate data collection. After the specified test duration, the pressure is gradually released, and the pipes are meticulously inspected for any permanent deformation or residual stress. This inspection may involve visual examination, dimensional measurements, or non-destructive testing techniques like ultrasonic testing or magnetic particle inspection. The test results are then assessed against the relevant industry standards or specifications to determine if the pipes comply with safety and performance requirements. If the pipes pass the hydrostatic pressure test, they are considered suitable for their intended application. However, if any issues or failures are identified, further investigation, analysis, or corrective actions may be necessary before the pipes can be approved for use. In conclusion, hydrostatic pressure testing plays a vital role in ensuring the quality and reliability of ductile iron pipes. By subjecting these pipes to rigorous testing procedures, manufacturers can provide customers with pipes that meet the highest standards of safety and performance.
- Q: Are ductile iron pipes resistant to environmental stress cracking?
- Yes, ductile iron pipes are highly resistant to environmental stress cracking.
- Q: How are ductile iron pipes protected from external damage?
- Ductile iron pipes are protected from external damage through the application of protective coatings. These coatings act as a barrier, shielding the pipes from corrosion and other forms of external damage. Additionally, the pipes may be encased in concrete or installed in a casing pipe to provide further protection against external forces and impacts.
