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. Our company produces ductile iron pipe capable of withstanding high internal pressure, during the pressure test, the test pressure is higher than the international dimension and the European dimension the 1MPa. Ductile iron pipe also has good resistance to external pressure ductile iron pipe prices, can reduce the pipe bed and a protective layer made of ductile iron pipe prices requires that pipeline economical and reliable; In addition, zinc spray, spray asphalt paint, lining cement and other measures to ensure that the casting of the inner and outer corrosion resistance. Zinc spray my company's compliance with ISO8179 quality delineation, per square meter of the pipe minimum amount of 130g dn800 with zinc ductile iron pipe prices, asphalt paint thickness not less than 70μm, cement mortar lining comply with ISO4179 quality delineation guarantee mortar sturdy chamber, smooth, strong adhesion.
