Ductile iron pipe scope for gas, water, such as water pipe network transformation, municipal pipe network transformation, industrial water and other liquids transported (wine) delivery. Flexible interface cast iron drainage pipe is a gravity sewage pipe, widely used in high-rise buildings of sewage, rainwater drainage and ventilation. Ductile iron pipe with high quality low sulfur, low phosphorus pig iron, equipped with seed manganese, silicon and other rare materials, cast iron water through a special inoculation, the grain structure refinement, has greatly improved the tensile strength and impact of straight pipe centrifugal casting process performance, high-speed rotation of the product more compact organization. Corrosion-resistant, high strength water will no noise in use for more than 50 years of easy maintenance, easy installation and fast construction can be cut. Nominal DN (100-800) * Thickness (6.5-15.3) length L6000mm water-cooled metal ductile iron pipe and pipe fittings. Ductile iron pipe water main component of carbon, silicon, manganese, sulfur, phosphorus and magnesium. On the ferrite and pearlite matrix distributed a certain number of spherical graphite, different caliber and in accordance with the requirements of the elongation of the nominal ratio of the matrix structure of ferrite and pearlite different, small-diameter ratio of pearlite generally not more than 20%, large diameter generally controlled at about 25%. Minimum tensile strength: 420 / Mpa, minimum yield strength 300 / Mpa, the minimum elongation of 7%. Ductile iron pipe performance standards GB / T13295-2008 ISO2531 / 2008. Widely used in water, oil pipelines. As well as food, pharmaceutical and chemical industry production process pipe network.
