Ductile iron pipe is defined using the 18th over after adding cast iron ball agent, after the high-speed centrifugal machine centrifugal ductile iron pipe cast, called "ductile iron pipe", referred to the tube, ductile iron pipe and ductile tubes. Ductile iron pipe, compared with gray cast iron pipe, high strength, good toughness, thin wall, metal with less, can withstand high pressure, the effective length of 5 m and 6 m; press thickness different points P, G two. Is the development direction of the cast iron pipe. Companies specializing in drainage pipes, ductile iron pipe, ductile iron pipe fittings EPC, tee, short tube, elbow, plugging, repair section, cast iron pipes and pipe fittings. Ductile iron pipe water main ingredients are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Minimum tensile strength: 420 / Mpa, ductile iron pipe, minimum yield strength: 300 / Mpa, the minimum elongation 7% GB / T13295-2008 ISO2531-2009 Diameter: DN80-DN2600 advantage of ductile iron pipe water supply: 1, energy conservation The main material is sand, stone, local materials. 2, not aging, small thermal expansion and contraction, should be long-term exposure to sunlight, stored at room temperature more than 40 ℃. 3, high strength, high compression performance, construction unlikely to cause deformation. The company head size default hair STO / Remittance / Yuantong / pass / rhyme! My company sells ductile iron water pipe, perennial and Xinxing Ductile Iron Pipes, Saint-Gobain cast pipe, ductile iron pipe water supply, Jinan Steel casting, An Yong-steel cast pipe, Shanxi Xuan's casting, casting and other global Xin available customer references, Shandong ductile iron pipe, 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.
