Yunnan ductile iron pipe water supply

Advantages of centrifugal ductile iron pipe: as an excellent water supply pipe, should have the following characteristics: high strength, corrosion resistance, high pressure, low accident rate, long life, high elongation. In the water pipeline project in the main use of pipe cement pipe, gray iron pipe, ductile iron pipe and steel pipe. Casting system, ductile iron pipe is three times the strength gray iron tube elongation gray iron pipe and ductile iron pipe is 0 to 10%, the corrosion resistance is 30 times more iron pipe gray iron pipe, gray iron pipe longer life , all kinds of performance comparison determines the performance of the alternative gray iron pipes. The traditional gray iron pipe because the material more brittle, less strength and toughness, the use of mechanical interfaces, unable to withstand high internal and external load when used, often inevitably occur explosion, excluded, broken, cracked and so on, in case to geological conditions, when the external load conditions change, prone tube brittle fracture, dislocation accidents and leaks, and now has been basically out of the market. Cement pipes can provide large-caliber products, but higher transportation and security costs, currently used only in the lower economic level areas; and poor corrosion resistance of steel, life is short, relatively complex construction, high construction costs, now also gradually withdraw the water supply network market.
