Q:What is the disadvantage of nodular cast iron in excess of silicon?
Therefore, the increase of silicon content in nodular iron greatly improves the strength index and reduces toughness. Ductile iron has a greater crystalline undercooling and a tendency to chill when treated by spheroidizing, and silicon reduces this tendency.
Q:What are the specifications for the installation of water ball iron pipes?
Ductile cast iron pipe is characterized by mild, high, thin wall, pressure resistance, impact resistance, corrosion resistance, seismic resistance and other properties. The flexible interface is used for the pipeline interface, and there is a certain elongation and deflection angle. The utility model has the advantages of the raw iron pipe and the steel pipe material, and avoids the defects of iron and steel.
Q:General cast iron prices now
Hello friends, Tianjin is in Shandong Qingdao 6500 7300 yuan / ton to 7100 yuan a ton of Zhejiang 7500 to 9000 yuan a ton, this is a great relationship, and the production of raw materials, for reference only, we are ductile casting manufacturers, the information can not say 100% accurate but can reference.
Q:An urban infrastructure construction, water supply pipe is ductile iron pipe and PE pipe, thank you
Water supply pipe is the first choice, with high cost performance. Compared with the PE pipe, from the installation time, ductile pipe PE pipe installation is simple and rapid, and after the installation of internal and external bearing pressure better;
Q:What are the interface forms of ductile iron pipes? The best drawings are available. Thank you
Because of this interface and the corresponding T sealing aprons can withstand greater deflection angle and greater tolerances, especially suitable for unstable formations and corners.
Q:How can the ductile iron pipes be treated with corrosion protection?
Cement mortar lining + special coatingThe internal corrosion prevention measures are suitable for pipes conveying sewage, and the corrosion resistance of lining can be improved.
Q:What is the DN400 installation charge for ductile iron pipes?
Labor cost: refers to the total amount of wages according to the provisions of the payment to the construction and installation works in the production of workers and ancillary production units of workers costs.
Q:Why does the cast iron pipe always run off when testing?
If the pipe is exposed for pressure test, you must add a pier, or else the fittings fly out. You are not surprised. At the same time, the pressure test before the ink tube to make full immersion bubble discharge clean, or a big easy gas pressure pipe explosion.
Q:When the ductile iron pipe is pressed, the three links are always running out. What should be done?
If the conventional backfill soil pressure, pipe fittings installed properly, the phenomenon will not appear.
Q:QT400-10 nodular cast iron requires hardness of HRC47~51. Why can't quench hardness be reached?
Because of the high tempering stability of the nodular iron, the tempering temperature is 400-450 degrees, and the tempering time is 1 hours.
