Supply ductile iron pipe main ingredients are carbon silicon manganese sulfur phosphorus and magnesium. Distributed a certain number of spherical graphite on ferrite and pearlite matrix. Different caliber and for elongation requirements based on the nominal. Matrix the proportion of the organization ferrite and pearlite pearlite different small-diameter ratio does not exceed 20% of the general control of the large diameter of about 25 percent minimum tensile strength:... 420 / Mpa minimum yield strength of 300. / Mpa. minimum elongation of 7%. ductile iron pipe performance standards GB / T13295-2008 ISO2531 / 2008. Widely used in water transmission pipeline. And food. Pharmaceuticals. Chemical industry production process pipe network. Nominal DN (50-300) * thickness T (3.5-7.0) length L3000mm flexible cast iron pipe and fittings. Strictly follow the requirements of GB12772-2008. Adopts the international advanced production technology and centrifugal casting product having a dense metal structure inside and outside finish The walls thin and uniform resistance to corrosion. convenient installation and transportation, etc., especially in earthquake has a unique advantage. fire. No noise. recycling use, etc. is widely used in high-rise building drainage. ventilation., and in the national key projects A higher quality engineering and seismic construction fire safety requirements are mandatory recommended. 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-Interface .K9 grade ductile iron pipe water supply 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 dn400 ductile iron pipe prices, 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 100mm diameter ductile iron pipe prices, mm; K - thickness level factor, taking a series of integers: 7,8 , 9,10,11,12 ... virtues of the company's main business of ductile iron pipe, ductile iron pipe and related fittings, rubber seal ring, iron and steel smelting and rolling processing, foundry products in which casting: Production capacity 800 000 tons, diameter DN80 ~ DN2600mm dn300 ductile iron pipe prices, T-type, K, S-type, N1 type, from a variety of interfaces and other forms anchored ductile iron pipe for different terrain conditions, using cement mortar, polyurethane, ceramics and other anti-corrosion epoxy-lined ductile iron pipe, meet the requirements of different water delivery ductile iron pipe prices, ductile iron and zinc coating finish coating and polyurethane tube wall corrosion processing technology for different soil corrosive environmental conditions, is urban water supply, gas pipe ideal.
