Fire water supply pipeline is an important facility used to transport fire fighting water, which plays a vital role in buildings, factories and other public places. According to the information provided by you, the fire water supply pipes mentioned here include three different diameters of ductile iron pipes: DN150, DN100 and DN200.
DN150: The "DN" here stands for Nominal Diameter, while the number 150 indicates that the nominal inner diameter of the pipe is 150 mm. This specification of ductile iron pipe is suitable for medium sized fire protection systems and can provide sufficient flow to meet the fire safety needs of general buildings or small industrial areas.
DN100: Similarly, "DN100" refers to a ductile iron pipe with a nominal inner diameter of 100 mm. Compared to the DN150, it is more suitable for smaller scale or less water-intensive applications. For example, this size may be chosen as the main fire water supply line in some residential communities or low-rise commercial buildings.
DN200: Finally, "DN200" refers to a large-caliber ductile iron pipe with a nominal inner diameter of 200 mm. This type of pipeline is usually used in large public facilities such as shopping malls, hospitals and other places, or in cases where a large amount of rapid water supply is required, such as the construction of the main fire pipe network in the high-rise building community.
It is worth noting that although these three different diameters of ductile iron pipes can be used to build fire water supply systems, the specific specifications need to be determined according to the actual situation, such as taking into account site conditions, expected water consumption and other factors to make a decision. In addition, no matter what type of materials and specifications are used, it is necessary to ensure that the installation of the entire system meets the relevant national standards and technical specifications to ensure its safe and reliable operation.
