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 of ductile iron pipe, grain structure refinement, greatly improved the tensile strength of straight pipe centrifugal casting process and impact resistance, 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. GB DN1300 ductile iron pipe, ductile iron pipe, ductile iron pipe prices GB DN1200 ductile iron pipe, GB k9 ductile iron pipe, ductile pipe to function as excellent mechanical properties and external quality, is the cause of piped water bearer, its super bearing capacity, reliable sealing performance, unmatched corrosion protection and water quality assurance system, so that families piped water near perfect, even in complex terrain balanced saline soils, wetlands, slope and high desert, but also Water task well done new ductile pipe, ductile iron has some frost resistance in the form of spherical graphite is generally graphite size of 6-7 DN1500 ductile iron pipe, cast pipe requirements on quality ball level control 1-3 grade (ball rate ≥80%), Guigang ductile iron pipe prices thus the mechanical properties of the material itself has been good improvement, with the nature of iron, steel performance. Annealed ductile iron pipe, the microstructure of ferrite and pearlite, good mechanical properties. Due to ductile pipe specification generally refers to the inner diameter, PE pipe size generally refers to the outer diameter, Guigang ductile iron pipe prices because under the same standard conditions, the ductile pipe can achieve greater runoff; from a comprehensive installation and maintenance costs, the ductile pipe has a more favorable price. 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, mm; K - thickness level factor, taking a series of integers: 7,8,9,10, 11,12 ...
