k9 grade ductile iron pipe is ideal for urban water supply pipes, gas pipeline network, 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 ; water-cooled metal mold centrifugal ductile iron pipe production technology and equipment in 1994 through the national scientific and technological achievements; ductile iron pipe the year 1994 was named national new products; DN100-1600mm ductile iron pipe technology and equipment through the state machinery Organization New products, new technology achievement appraisal; epoxy ceramic-lined ductile iron pipe, ductile iron pipe k9 assess emerging scientific and technological achievements by the Ministry of Construction, the technical indicators have reached the United States inspection standards k9 ductile iron pipe of low export volume to fill the Blank; ductile iron pipe for the China Water Supply Association, China City Gas Association recommended products. Centrifugal ductile iron pipe in 2002 won the national quality metallurgical products Gold Award. The main components of ductile iron pipe carbon, silicon, manganese, sulfur, phosphorus and magnesium. On the ferrite and pearlite matrix distributed a certain number of spherical graphite, different caliber and to extend the requirement based on the nominal rate, the proportion of the matrix structure of ferrite and pearlite is different, small-diameter ratio of pearlite generally not more than 20% of large diameter generally controlled at about 25%. Minimum tensile strength: 420 / Mpa, minimum yield strength 300 / Mpa, a minimum elongation of 7%. Ductile iron pipe performance standards GB / T13295-2008ISO2531 / 2008. My company sells ductile iron water pipe, perennial and Xinxing Ductile Iron Pipes k9 ductile iron pipe, Saint-Gobain casting, casting Jinan Iron and Steel, the steel forever cast pipe, Shanxi Xuan's casting, Xin Global k9 ductile iron pipe casting, etc. standards for customer references, ductile pipe diameter from DN80-DN2600, the company's products are mainly K9 grade ductile iron pipe, ductile iron pipe water supply, gray cast iron pipe, ductile iron pipe, ductile iron pipe from anchor, T- Interface ductile iron pipe, K-type interfaces ductile iron pipe. Ductile iron pipe water main control parameters selected for the nominal diameter, operating pressure, connections and so on. Ductile iron pipe water characteristics: mild high, thin wall, pressure, impact resistance, corrosion resistance, earthquake and other properties. Pipeline interface with flexible interface, but also a certain elongation and deflection angle. He has the advantages of cast iron pipe and pipe material, avoiding the disadvantages of iron and steel. Ningxi k9 ductile iron pipe, ductile iron pipe Weifang k9, by virtue Pipe Co., Ltd.
