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: Steel plastic pipe, ductile iron pipe, steel pipe difference: The steel plastic pipe, the outer layer is made of steel, the inner cover of organic material, not easy to transport corrosive medium, suitable for delivery of utilities, tap water and toxic corrosive medium, not suitable for high temperature medium, pipe price is high, very difficult to install and manufacturers warranty period is generally 10 years.

Q: How are ductile iron pipes protected against external corrosion?: Ductile iron pipes are protected against external corrosion through a combination of manufacturing processes and external coatings. The first line of defense is the inherent corrosion resistance of ductile iron itself. The iron is treated with a special alloying element, typically magnesium, which forms a protective layer on the surface of the pipe. This layer acts as a barrier against corrosion and helps to extend the lifespan of the pipe. In addition to the corrosion-resistant properties of the iron, ductile iron pipes are also externally coated with protective materials. One common method is to apply a layer of asphaltic or bituminous coating to the pipe's surface. This coating acts as a barrier against moisture and corrosive substances in the soil, preventing them from coming into contact with the iron. It also provides a layer of insulation, reducing the likelihood of galvanic corrosion. Another method of external corrosion protection is the use of fusion-bonded epoxy (FBE) coatings. FBE is a thermosetting resin that is applied to the surface of the pipe and then heat-cured to form a strong and durable coating. This coating provides excellent resistance against corrosion, abrasion, and impact, making it a popular choice for ductile iron pipes in harsh environments. In some cases, additional protective measures such as cathodic protection systems may be employed. These systems use electric currents to counteract the corrosion process by supplying electrons to the pipe's surface. This helps to prevent corrosion from occurring, especially in areas where the coating may have been damaged or compromised. Regular maintenance and inspection are also crucial in ensuring the long-term protection of ductile iron pipes against external corrosion. This includes periodic cleaning, repair of any coating damages, and monitoring the integrity of the protective layers. Overall, the combination of the inherent corrosion resistance of ductile iron, external coatings, and maintenance practices ensures that ductile iron pipes are well-protected against external corrosion, allowing them to have a longer lifespan and deliver reliable performance in various applications.

Q: What is the composition of ductile iron pipes?: Ductile iron pipes consist mainly of iron, with small amounts of carbon, silicon, and other alloying elements. The iron content typically ranges from 90% to 94%, while carbon content is usually around 3% to 4%. Silicon is added between 1.5% to 3%, which enhances the ductility and strength of the iron. Smaller quantities of manganese, sulfur, and phosphorus may also be present. The composition of ductile iron pipes is carefully engineered to achieve specific properties. By adding carbon and silicon, the hardness and strength of the iron are improved, making it suitable for demanding applications. These alloying elements also contribute to the pipes' ductility, allowing them to be easily bent and molded without breaking. In summary, the composition of ductile iron pipes is designed to strike a balance between strength, ductility, and resistance to corrosion. This makes them ideal for use in water and sewage systems, where they can endure high pressure, bear heavy loads, and resist the corrosive effects of water and other chemicals.

Q: Can ductile iron pipes be used for underground oil and gas pipelines?: Yes, ductile iron pipes can be used for underground oil and gas pipelines. Ductile iron is a strong and durable material that can withstand the high pressure and corrosive nature of oil and gas transportation. It has excellent tensile strength and impact resistance, making it suitable for underground applications. Ductile iron pipes are also resistant to external loads, which is important for underground pipelines that may be subject to soil movement or heavy traffic. Furthermore, ductile iron pipes can be easily jointed, allowing for efficient installation and maintenance. However, it is important to consider factors such as soil conditions, environmental factors, and specific project requirements before choosing ductile iron pipes for underground oil and gas pipelines.

Q: What are the meanings of cast iron pipe wall thicknesses LA, A and B respectively?: Cast iron pipes (Cast, Iron, Pipe), cast cast pipe. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small. According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds. 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: What is the expected joint flexibility of ductile iron pipes?: The expected joint flexibility of ductile iron pipes is typically high, as they are designed to accommodate slight movements and stresses caused by ground settlement or thermal expansion and contraction.

Q: How many degrees can the ductile iron pipe be each?: Minimum tensile strength: 420/Mpa, minimum yield strength: 300/Mpa, minimum elongation 7%.

Q: How long is the service life of the cast iron pipe, and the time of use of ductile iron pipes?: Ductile iron is a new type of pipe, as long as we use it properly, the quality of its products, then the use of ductile iron pipes for 20-35 years, basically no problem. But whether it is ductile cast iron pipe, or some other things, the use of more years, and more or less, there will be some problems, ductile iron pipe can not escape the robbery. However, as long as we use the ductile iron pipe in the process of careful care, the service life of the problem is not to worry about.

Q: How does ductile iron pipe perform in areas with high water hammer?: Ductile iron pipe performs well in areas with high water hammer due to its inherent strength and flexibility. Its ability to absorb and dissipate the energy generated by water hammer helps to prevent pipe failures and minimize the damaging effects of pressure surges. This makes ductile iron pipe a reliable choice for water distribution systems in such areas.

Q: How does ductile iron pipe handle thermal expansion and contraction?: The effectiveness of ductile iron pipe in dealing with thermal expansion and contraction is well-known. This is primarily due to its unique material properties and design characteristics. To begin with, it is worth noting that ductile iron pipe has a high coefficient of linear expansion. This means that it experiences relatively more expansion and contraction compared to other materials when exposed to temperature changes. As a result, the pipe is able to accommodate thermal expansion and contraction without causing excessive stress or deformation. Furthermore, the design of ductile iron pipes includes flexible joints. These joints, such as push-on or mechanical joints, are capable of absorbing the movement caused by thermal expansion and contraction. By providing a certain level of flexibility, these joints enable the pipe to expand and contract within a specific range without compromising its structural integrity. Additionally, the material composition of ductile iron itself plays a significant role in its ability to handle thermal expansion and contraction. Ductile iron is a type of cast iron alloy that contains nodular graphite in its microstructure. This composition provides the pipe with enhanced ductility and tensile strength. As a result, the pipe is able to withstand the stresses induced by thermal expansion and contraction without fracturing or breaking. Overall, ductile iron pipe is designed and produced in a manner that allows it to effectively deal with thermal expansion and contraction. Its high coefficient of linear expansion, flexible joints, and ductile material properties all work together to ensure that the pipe can accommodate temperature changes without causing any significant issues or structural failures.
