Ductile iron pipe is superior to other pipes shared by Carbon Steel Pipe Fittings Factory.
Performance comparison of ductile iron pipe and steel pipe:
Steel pipe can be divided into slit steel pipe and seamless steel pipe, generally used in the middle channel of water pipe slit pipe. Compared with ductile iron pipe, steel pipe has the advantages of good toughness, high tensile strength, thin pipe wall, high pressure resistance, long pipe, less interface, etc. The biggest disadvantage is poor corrosion resistance, high price. So in general, in addition to small diameter pipe and special works.
Performance comparison between ductile iron pipe and universal cast iron pipe:
Ductile iron pipes are made by adding magnesium, calcium and other alkaline earth metals or rare metals into the raw materials of ordinary cast iron pipes. Casting process of nodular cast iron pipe with method of continuous casting, hot casting method and the water-cooling centrifugal casting method, the water cooling method for the world's most advanced technology, different process ductile iron technical performance compared with ordinary cast iron pipe, it not only maintain the corrosion resistance of ordinary cast iron pipe, and has high strength, good toughness, wall thin, light weight, impact resistance, bending performance, easy installation, etc. Therefore, ductile iron pipes are not only widely used abroad, but also widely used in China. In many areas of China, ductile iron pipes have been widely used in medium and small diameter water pipes.
Ductile iron pipes are compared with the performance of PVC plastic pipe: compared with the ductile iron pipes, PVC pipe is the feature of the lining is smooth, light weight, good corrosion resistance, fouling prevention performance, low price, but the disadvantages are more, mainly has the following points: (1) easy to aging, heat bilges cold shrink, unfavorable and long-term exposure to sunlight, save the room temperature should not be greater than 40 ℃. (2) low strength, poor compression performance, improper construction is easy to cause deformation. (3) poor rigidity, poor deflection, easy to cause leakage.
Performance comparison between cast iron pipe and prestressed reinforced concrete pipe: ductile iron pipe and prestressed reinforced concrete pipe (suitable for large diameter pipe, the maximum diameter has exceeded 2000), with the following characteristics: (1) energy saving, the main materials are sand and stone, local materials can be used. (2) large weight, brittle texture, difficult cutting and chiseling, relatively difficult construction. (3) the working pressure is 20% to 40% lower than that of the spheroidal ink tube, which is 0.15-0.25 MPa. (4) the maximum deflection Angle is 1.5 degrees, while the maximum of ductile iron pipe is 3.0 degrees, so the terrain adaptability of prestressed reinforced concrete pipe is poor.
