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 cast iron pipe?: Divided into gray cast iron pipe and nodular cast iron pipe according to different material. According to the interface form, it is divided into flexible interface, flange interface, self anchored interface, rigid interface and so on. Among them, the flexible iron pipes rubber sealing ring; flange interface cast iron pipe flange fixed in the rubber pad, the flange gasket sealing; rigid interface cast iron pipe socket is large, straight pipe is inserted, sealed with cement, this technology has been basically eliminated.

Q:Why does the cast iron pipe always run off when testing?: The pipeline is installed, straight section of each pipe will be added pier, concrete pipe, elbow, three links should also have concrete pier, specific installation method according to GB Atlas 03SS515, and the straight pipe to soil, pipeline interface will be exposed, easy to check.

Q:What is the typical wall thickness of ductile iron pipes?: The typical wall thickness of ductile iron pipes varies depending on the size and the intended use of the pipe. Generally, ductile iron pipes have a wall thickness ranging from 0.25 inches (6.35 mm) to 0.5 inches (12.7 mm). However, for larger diameter pipes or those used in high-pressure applications, the wall thickness can be even greater. It is important to consult industry standards and specific project requirements to determine the appropriate wall thickness for a ductile iron pipe.

Q:Are ductile iron pipes suitable for underground applications?: Yes, ductile iron pipes are suitable for underground applications. Ductile iron pipes are known for their durability, strength, and corrosion resistance, making them an ideal choice for underground installations. These pipes can withstand heavy loads, ground movement, and external pressure, making them suitable for burying underground. Additionally, ductile iron pipes have a long lifespan, often lasting more than 100 years, which is crucial for underground applications where accessibility and maintenance can be challenging. Overall, their robustness and longevity make ductile iron pipes a reliable and suitable choice for underground applications.

Q:Are ductile iron pipes suitable for airport runway drainage?: Yes, ductile iron pipes are suitable for airport runway drainage. Ductile iron pipes have excellent strength and durability, making them capable of withstanding heavy loads and extreme conditions, which are often encountered in airport operations. They are resistant to corrosion, which is crucial in a drainage system that may be exposed to various chemicals and environmental factors. Ductile iron pipes also have smooth inner surfaces, allowing for efficient flow of water and preventing blockages that could disrupt the drainage system. Additionally, they are easy to install and maintain, making them a reliable choice for airport runway drainage systems.

Q:How do ductile iron pipes compare to PVC pipes in terms of strength?: Ductile iron pipes are generally stronger than PVC pipes in terms of their ability to withstand external loads and pressure. Ductile iron has a higher tensile strength and can handle higher operating pressures, making it suitable for a wider range of applications, including underground and high-pressure systems. PVC pipes, on the other hand, have lower tensile strength and are more prone to cracking or bursting under high pressure or when exposed to extreme temperatures. However, PVC pipes are lighter and easier to handle, making them more convenient for installation and maintenance in certain situations.

Q:What is the average cost of ductile iron pipes?: The average cost of ductile iron pipes can vary depending on various factors such as diameter, length, and location. On average, ductile iron pipes can range from $30 to $100 per linear foot. For example, a 6-inch diameter ductile iron pipe with a length of 20 feet may cost around $600 to $2,000. It's important to note that these prices are estimates and can change based on market conditions, project specifications, and supplier pricing. Therefore, it is recommended to consult with local suppliers or contractors to obtain accurate pricing information for specific projects.

Q:How can 4 inch ductile iron pipe be connected with 2 inch galvanized pipe?: Ductile cast iron used for more than 18 by adding nodulizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.

Q:What does ductile iron pipe "K" mean?: K means wall thickness registration, general water supply and drainage, now China uses K9, and some countries in South America, such as Brazil, use K7.The wall is thick =k (DN/1000+0.5), such as K9's DN500 tube, with a wall thickness of =9* (500/1000+0.5) =9mm

Q:Are ductile iron pipes suitable for irrigation systems in agricultural fields?: Yes, ductile iron pipes are suitable for irrigation systems in agricultural fields. Ductile iron pipes have excellent strength, durability, and corrosion resistance, making them ideal for carrying water in irrigation systems. They can withstand high pressure and heavy loads, ensuring reliable water supply to agricultural fields for irrigation purposes.
