Ductile iron pipe scope for gas, water, such as water pipe network transformation, municipal pipe network transformation, industrial water transportation and other liquid (wine) delivery. Flexible interface cast iron drainage pipe is a gravity sewage pipe, widely used in high-rise buildings of sewage, storm drain and ventilation. Ductile iron pipe made of high quality low sulfur, low phosphorus pig iron, equipped with the kind of manganese, silicon and other rare materials, cast iron water through a special inoculation, the grain structure refinement, greatly improved the tensile strength and impact of straight pipe performance of ductile iron pipe, high-speed rotation of the centrifugal casting process to make products 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. k9 grade ductile iron pipe T-interface ductile iron pipes of urban water supply water pipes GB K9 grade cast iron pipe sprayed zinc prices T-ductile iron pipe, ductile iron pipe specifications --- k9 grade ductile iron pipe specifications Spot / T-interfaces to ductile pipe .K9 grade cast iron pipe, ductile iron pipe (Ductile Cast Iron Pipes) k9 is a wall thickness of grade standards, 9 is a factor. e = k × (0.5 + 0.001 × DN) e is the thickness, DN is the nominal diameter centrifugally cast pipe minimum wall thickness of 6mm, centrifugally cast iron pipe fittings and a minimum wall thickness of 7mm. e = K (0.5 + 0.001DN) where: e - standard wall thickness, mm; DN - nominal diameter DN1300 ductile iron pipe, mm; K - thickness level factor, taking a series of integers: 7-8, 9,10,11,12 ... centrifugal ductile iron pipe is urban water supply, ideal gas network pipe DN1600 ductile iron pipe, high-set strength, ductility, and corrosion resistance and strong advantages, with the nature of iron, steel performance, is the traditional cast iron pipes and upgrading of ordinary steel products; the company's existing four ductile iron pipe production plant, casting product specifications from DN80-2600mm, there are T-type, K-type, N-type, S-type, and other Interface form; cooled metal mold centrifugal ductile iron pipe production technology and equipment 94 through the national scientific and technological achievements; ductile iron pipe was named the year 1994 state-level new products; DN1300 ductile iron pipe, ductile iron pipe _ _ Lianyungang virtue of Industry by the chat Urban virtue Industry Limited.
