5.FAQ:

We have organized several common questions for our clients，may help you sincerely：

1.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.

2.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:How is ductile iron pipe different from cast iron pipe?: Ductile iron pipe is different from cast iron pipe in terms of its composition and strength. Ductile iron pipe is made from a type of iron known as ductile iron, which contains small amounts of carbon and other elements that enhance its flexibility and toughness. Cast iron pipe, on the other hand, is made from cast iron, which is more brittle and less flexible than ductile iron. This makes ductile iron pipe more resistant to cracking and breaking, making it suitable for high-pressure applications.

Q:What is the expected surge pressure rating of ductile iron pipes?: The expected surge pressure rating of ductile iron pipes can vary depending on various factors such as the diameter and thickness of the pipe, the type of joint used, and the specific manufacturer's specifications. However, ductile iron pipes are generally designed to withstand surge pressures between 150% to 200% of their working pressure rating. This means that if a ductile iron pipe has a working pressure rating of, for example, 250 psi, it can typically handle surge pressures of up to 375 psi to 500 psi. It is important to consult the manufacturer's specifications and guidelines for accurate surge pressure ratings specific to the ductile iron pipes being used.

Q:How does ductile iron pipe handle changes in pipe diameter or size?: Ductile iron pipe offers a convenient solution for dealing with alterations in pipe diameter or size. Its excellent flexibility and capacity to adapt to changes in pipe dimensions without compromising its structural integrity are a result of its unique composition, which contains a significant amount of graphite nodules that provide ductility and elasticity to the material. When faced with adjustments in pipe diameter or size, ductile iron pipe can be easily manufactured or modified to meet specific requirements. It can be cast or fabricated in different diameters and lengths, allowing for seamless integration and adaptability within a pipeline system. This versatility proves particularly advantageous when connecting different pipe sizes or making alterations to the pipeline layout. Furthermore, the superior mechanical properties of ductile iron pipe enable it to withstand the stresses and forces associated with changes in pipe diameter or size. It possesses high tensile strength, impact resistance, and durability, ensuring its ability to handle the internal and external pressures exerted on the pipe during operations. Moreover, the jointing systems employed with ductile iron pipe contribute to its ability to handle changes in diameter or size. Various joint types, including push-on, restrained, or mechanical joints, provide secure and leak-free connections between different pipe sections. These joints facilitate easy assembly and disassembly, enabling efficient adjustments to the pipe diameter or size as required. In conclusion, ductile iron pipe is well-equipped to handle changes in pipe diameter or size due to its inherent flexibility, adaptability, and robustness. Its composition, manufacturing capabilities, and jointing systems all contribute to its capacity to accommodate variations in pipe dimensions without compromising its performance.

Q:Can ductile iron pipes be used for water distribution networks in rural areas?: Yes, ductile iron pipes can be used for water distribution networks in rural areas. Ductile iron pipes have excellent strength and durability, making them suitable for various applications, including water distribution. They can withstand high pressure, provide a long service life, and have good resistance to corrosion and external stresses. Additionally, ductile iron pipes are relatively cost-effective and require minimal maintenance, making them a reliable choice for water distribution networks in rural areas.

Q:How many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?: This is such a small piece, do not worry about shrinkage, mainly pay attention to sand hole and slag. With Disa wet molding line, a box of more pieces, suitable for mass production, defects will be relatively less. By using other methods (resin sand coated sand, etc.) can also be the main attention, don't type it, then the level of liquidity and relatively ductile iron, gray iron poor, sand and gas can not go up, sand holes or pores will spread in the discus plane.

Q:Are ductile iron pipes resistant to impact damage?: Ductile iron pipes are known for their exceptional strength and durability, making them highly resistant to impact damage. Due to their unique composition, which includes a higher percentage of carbon and silicon, ductile iron pipes possess excellent toughness and flexibility. This allows them to withstand external forces and impacts, such as heavy construction equipment or accidental impacts during installation or maintenance activities. Additionally, ductile iron pipes have a high resistance to cracking and fracturing, further enhancing their ability to withstand impact damage. However, it is important to note that while ductile iron pipes are highly resistant to impact damage, they are not completely immune. Extreme or repeated impacts may still cause damage, albeit to a lesser extent than other types of pipes. Regular inspections and maintenance are crucial to identifying and addressing any potential impact damage to ensure the long-term integrity and performance of ductile iron pipes.

Q:Does the cast iron pipe for spheroidal graphite need corrosion protection when laying underground?: Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..

Q:Water supply pipe is ductile iron, then it's fittings and valves and other parts must be ductile iron?: Not always。Valve material selection is mainly determined by the fluid medium.The medium can be divided into gas, liquid, corrosive gas, liquid and oil. According to different media, temperature, and pressure levels, choose different materials, plastic, cast iron, cast steel, stainless steel and so on.

Q:Are ductile iron pipes resistant to UV degradation?: Ductile iron pipes are not inherently resistant to UV degradation. Exposure to ultraviolet (UV) radiation from the sun can cause the degradation of various materials, including ductile iron. However, it is important to note that the rate of UV degradation in ductile iron pipes is relatively slow compared to other materials such as plastics or rubber. To mitigate the effects of UV degradation on ductile iron pipes, protective measures can be taken. Coating the pipes with a suitable UV-resistant paint or applying an external protective layer can help minimize the impact of UV radiation. Additionally, proper installation and maintenance practices can also contribute to the longevity and durability of ductile iron pipes. It is worth mentioning that while UV degradation may not be the primary concern for ductile iron pipes, other factors such as corrosion, chemical attack, or mechanical stress can still affect their performance and lifespan. Therefore, it is important to consider all potential environmental factors and apply appropriate protective measures accordingly.

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.
