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 the elongation of the requirements according to nominal. Matrix the proportion of the organization ferrite and pearlite pearlite differ small-diameter ratio is generally not more than 20% of the general control of large diameter of about 25% 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. Pharmacy. Chemical industry production process pipe network. Nominal DN (50-300) * wall thickness T (3.5-7.0) length L3000mm flexible cast iron pipe and pipe fittings. Strictly follow the requirements of GB12772-2008. Adopts the international advanced production technology and centrifugal casting product has a dense metal structure inside and outside finish The walls thin and uniform resistance to corrosion. Easy installation and transportation advantages, especially with a unique advantage in the earthquake. Fire. No noise. recycling use, etc. is widely used in high-rise building drainage. ventilation. and national key projects A higher quality engineering and seismic requirements for fire and other buildings were forced recommended.
