4.FAQ:
We have organized several common questions for our clients，may help you sincerely：
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.
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's the difference between cast iron pipe and steel pipe?
- Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
- Q: What is the composition of ductile iron pipes?
- Ductile iron pipes are primarily composed of iron, with small amounts of carbon, silicon, manganese, and trace elements such as sulfur and phosphorus.
- Q: How do ductile iron pipes handle ground movement near rivers and lakes?
- Due to their unique properties and construction, ductile iron pipes are an ideal choice for managing ground movement near rivers and lakes. These pipes, made from a type of cast iron known for its strength and flexibility, possess exceptional resistance to both ground movement and external forces. One notable characteristic of ductile iron pipes is their ability to endure bending and stretching without breaking. This remarkable flexibility enables the pipes to accommodate ground movements, whether caused by natural phenomena like soil settling, erosion, or even seismic activity. By absorbing and dispersing the stress induced by ground movement, these pipes minimize the risk of cracks or fractures. Moreover, ductile iron pipes exhibit high impact resistance, enabling them to withstand external forces such as pressure from shifting soil or heavy machinery. This quality makes them less susceptible to damage during ground movements in areas prone to erosion or flooding near rivers and lakes. Furthermore, ductile iron pipes feature smooth internal surfaces, reducing friction and resistance to the flow of water. This ensures efficient water transportation even in regions experiencing ground movement, preventing potential blockages or disruptions to the water supply system. To further enhance their ability to withstand ground movement, ductile iron pipes are commonly installed using flexible joints, such as restrained joints or push-on joints, depending on the specific project requirements. These joints allow the pipes to move slightly without causing harm to the overall system, providing additional protection against ground movement near rivers and lakes. In conclusion, ductile iron pipes possess the necessary strength, flexibility, impact resistance, and smooth internal surfaces to effectively manage ground movement near rivers and lakes. These qualities make them a reliable choice for water transportation systems in areas prone to ground movement, ensuring the creation of a durable and efficient infrastructure for the supply of water.
- Q: How are ductile iron pipes protected against internal corrosion caused by chemicals?
- To safeguard against internal corrosion caused by chemicals, ductile iron pipes implement various protective measures. Primarily, these pipes are equipped with either a cement mortar lining or an epoxy coating, creating a barrier between the water or sewage's chemical substances and the iron material. This barrier effectively prevents direct contact, thereby averting corrosion. Additionally, a corrosion-resistant polymer or bituminous coating is frequently applied to the pipes' exterior. This supplementary layer of protection shields the pipes from potential chemical exposure originating externally. Moreover, cathodic protection is a commonly employed technique to counter internal corrosion. Sacrificial anodes, typically composed of zinc or magnesium, are affixed to the pipes. Over time, these anodes undergo corrosion instead of the iron, sacrificing themselves to safeguard the pipes against chemical-induced corrosion. Furthermore, regular maintenance and monitoring play a crucial role in the prevention and rectification of corrosion issues. This entails routine inspections, cleaning, and prompt repair of any corroded or damaged areas. Overall, the integration of lining, external coating, cathodic protection, and maintenance practices ensures the comprehensive protection of ductile iron pipes against internal corrosion caused by chemicals. This prolongs their lifespan and guarantees the integrity of the pipeline system.
- Q: Can ductile iron pipe be used for pump stations?
- Certainly, pump stations can utilize ductile iron pipe. Ductile iron pipe is extensively employed in underground water and wastewater systems, including pump stations. It provides numerous benefits, including remarkable strength, durability, and resistance to corrosion, thus ensuring its appropriateness for such purposes. Moreover, ductile iron pipe seamlessly harmonizes with various pump types and is renowned for its extended lifespan, rendering it an optimal selection for pump station projects.
- Q: How does ductile iron pipe compare to PVC pipe in terms of performance and cost?
- Ductile iron pipe and PVC pipe have different characteristics in terms of performance and cost. Ductile iron pipe is known for its strength, durability, and ability to withstand high pressure and heavy loads, making it ideal for applications that require robust performance such as water distribution systems. On the other hand, PVC pipe is lightweight, corrosion-resistant, and more flexible, making it suitable for above-ground and non-pressurized applications like drainage systems. In terms of cost, PVC pipe is generally less expensive than ductile iron pipe, especially for smaller diameter pipes. However, as the diameter increases, ductile iron pipe becomes more cost-effective due to its superior strength and longer lifespan, which reduces maintenance and replacement costs over time. Ultimately, the choice between ductile iron and PVC pipe depends on the specific application, budget, and desired performance characteristics.
- Q: Can ductile iron pipe be used for wastewater treatment plant sludge dewatering?
- Ductile iron pipe is suitable for the dewatering of sludge in wastewater treatment plants. Its durability, strength, and resistance to corrosion make it a popular choice in these facilities. The pipes can withstand the harsh conditions and abrasive characteristics of the sludge dewatering process. Moreover, their leak-proof joints are essential in preventing any sludge leakage during dewatering. Furthermore, ductile iron pipes come in different sizes and are easy to install, making them a convenient option for wastewater treatment plant sludge dewatering.
- Q: What kind of valves are commonly used in ductile iron pipes?
- Gate valve, butterfly valve, globe valve, check valve flange of various valves, (but the pipeline used for water supply and some limitations of the transport medium may be prescribed valve type) now due to material improvements in the technology, in most cases, smaller pipe diameter is also large diameter pipe outlet valve, butterfly valve, because of the pipeline the large diameter pressure in the pipeline and water than the small caliber to open and close the valve, to human hard, efficiency is not high, so for butterfly valve,
- Q: How can the old water pipe ductile iron pipe be opened with three flanges?
- Cast iron pipe is not good then did not take the treatment is not good in the local search do you master plumbing to the scene to see the actual situation, some teachers have you unexpected strain interpretation way.
- Q: How are ductile iron pipes different from other types of pipes?
- Ductile iron pipes are different from other types of pipes primarily due to their enhanced strength and durability. Unlike traditional cast iron pipes, ductile iron pipes have a higher tensile strength and can withstand higher internal and external pressures. They are also less prone to cracking or breaking under heavy loads or impact, making them suitable for both above-ground and underground applications. Additionally, ductile iron pipes offer superior resistance to corrosion, which increases their lifespan and reduces maintenance requirements compared to other pipe materials.
