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: What is the composition of ductile iron pipes?: Ductile iron pipes are primarily composed of iron, along 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 in the range of 1.5% to 3%, which helps enhance the ductility and strength of the iron. Other alloying elements such as manganese, sulfur, and phosphorus may also be present in smaller quantities. The composition of ductile iron pipes is carefully engineered to achieve specific properties. The addition of carbon and silicon improves the hardness and strength of the iron, making it more suitable for demanding applications. The presence of these alloying elements also contributes to the ductility of the pipes, allowing them to be easily bent and molded without breaking. Overall, the composition of ductile iron pipes is designed to provide a balance between strength, ductility, and resistance to corrosion. This makes them ideal for use in water and sewage systems, where they can withstand high pressure, handle heavy loads, and resist the corrosive effects of water and other chemicals.
