My company sells ductile iron water pipe, perennial and Xinxing Ductile Iron Pipes, Saint-Gobain casting, casting Jigang, k9 ductile iron pipe, An Yong-steel cast pipe, Shanxi Xuan's casting, casting and other global Xin available customer references, ductile pipe diameter from DN80-DN2600, the company's products are mainly K9 grade ductile iron pipe, ductile iron pipe water supply, Ningxi k9 ductile iron pipe, gray cast iron pipe, ductile iron pipe, ductile iron pipe self-anchored , T Interface ductile iron pipe, ductile iron pipe emerging k9, 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. 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.
