Q: Fire water supply network adopts ductile iron pipe, the test pressure should be no more than MPa: To your selected fire pump highest lift 1.5 times to suppress, generally not more than 1.6MPa, if the use of ductile iron pipe, test pressure according to 2MPa to suppress.

Q: Are ductile iron pipes resistant to UV degradation?: UV degradation is not something that ductile iron pipes naturally resist. When they are exposed to sunlight, the UV radiation can cause degradation in various materials, including ductile iron. However, it is important to understand that the rate at which ductile iron pipes degrade due to UV radiation is relatively slow when compared to materials like plastics or rubber. To prevent UV degradation from negatively impacting ductile iron pipes, protective actions can be taken. These can include coating the pipes with a paint that is resistant to UV radiation or applying an external protective layer. By doing so, the impact of UV radiation can be minimized. Additionally, proper installation and maintenance practices can also contribute to the longevity and durability of ductile iron pipes. It is worth noting that while UV degradation may not be the main concern for ductile iron pipes, other factors like corrosion, chemical attack, or mechanical stress can still affect their performance and lifespan. Therefore, it is important to consider all potential environmental factors and take appropriate protective measures accordingly.

Q: What are the requirements for the hydrostatic test of ductile iron pipes?: The pipe work pressure P is less than 0.5MPa, the test pressure is 2P, the pipe work pressure is greater than 0.5MPa, the test pressure is P+0.5. After the water pressure rises to the test pressure, the pressure is fixed for 10 minutes, and the pipe joint and the pipe body are not damaged and leaked.

Q: What's the difference between grey cast iron pipe and ductile iron pipe?: Ductile iron is close to medium carbon steel and is much cheaper. Vermicular graphite iron is the best, but grey iron is worse and white iron is the worst. Therefore, the quality of ductile iron pipe with better quality and price is superior to other cast iron pipe fittings.

Q: Can ductile iron pipes be used in areas with high soil settlement?: Ductile iron pipes are suitable for areas with high soil settlement due to their strength and durability. They can withstand external loads and ground movement, making them an ideal choice for such areas. Additionally, these pipes have a high resistance to corrosion, making them even more suitable for use in areas with high soil settlement. However, it is important to consider factors such as proper installation techniques, appropriate bedding and backfill materials, and regular maintenance to ensure the longevity and performance of the ductile iron pipes in these areas. Consulting with a qualified engineer or pipe manufacturer can provide more specific guidance based on the site's conditions and requirements.

Q: How are ductile iron pipes joined to fittings and valves?: Ductile iron pipes are typically joined to fittings and valves using mechanical joint or push-on joint methods. The mechanical joint involves using a gland and a rubber gasket to create a tight seal when the pipe is bolted to the fitting or valve. On the other hand, push-on joint method uses a rubber gasket that is compressed when the pipe is pushed into the fitting or valve, providing a secure connection without the need for bolts or additional hardware.

Q: Luo what effect of ductile cast iron: Chromium can improve the hardness, strength and wear resistance of nodular iron, and increase bainite in bainite ductile iron.

Q: The difference between spheroidal graphite cast iron pipe and HDPE water supply pipe: Because the HDPE pipe flexibility is good, in the face of obstacles or trench excavation in straight pipe laying conditions can not directly, but the ductile iron pipe can not, it is sometimes necessary to use the words such as elbow or tube fittings to connect the transition. In this way, the HDPE pipe is superior to the ductile iron pipe in the pipe fittings.

Q: What does ductile iron pipe "ND200" mean?: Generally speaking, the diameter of the pipe can be divided into outer diameter, inner diameter and nominal diameter. The pipe is a seamless steel pipe pipe diameter by the letter D to represent, then additional outer diameter size and thickness, such as diameter of seamless steel pipe 108, a wall thickness of 5MM, denoted by D108*5, is also used outside said, such as De63 plastic pipe, such as reinforced concrete pipe, cast iron pipe, galvanized steel pipe, said the DN, in the design drawings is generally used to represent the nominal diameter, nominal diameter is a standard in order to design and manufacture and maintenance convenient set artificially, with nominal diameter, tube (or pipe) specification name.

Q: What is the DN400 installation charge for ductile iron pipes?: The wages paid under special circumstances: refers to the provisions of the state laws, regulations and policies, due to illness, injury, maternity leave, family planning leave, funeral leave, leave, leave, leave, regular shutdown, implementation of national or social obligations due to pay a certain percentage of wage hourly wage or salary when.
