  • What is a Cast Iron Pipe?

    Date: Nov. 23, 2020

    Cast Iron Pipe, a pipe made of cast iron. Cast iron pipes are used for water supply, drainage, and gas pipelines, and include straight cast iron pipes and pipe fittings. The labor intensity is small. According to different casting methods, it is divided into continuous cast iron pipe and centrifugal cast iron pipe. Among them, centrifugal cast iron pipe is divided into a sand mold and metal mold. According to different materials, it can be divided into gray cast iron pipe and ductile iron pipe. According to different interface forms, it is divided into a flexible interface, flange interface, self-anchored interface, rigid interface, etc.

  • How to Distinguish Gray Iron Valves and Ductile Iron Valves?

    Date: Nov. 11, 2020

    In terms of professional knowledge, the general nodular cast iron in the national standard is represented by QT400-15, QT400-18, etc. Where QT is the abbreviation of the first capital letter of ductile iron, 400 refers to the tensile strength of the part, 15. 18 refers to elongation. There are many ways to express nodular cast iron abroad, such as EN-GJS-400-15/18 in the European standard and GGG40/GGG40.3/GGG50 in the German standard.

  • Ductile Cast Iron Pipe Laying and Installation Plan

    Date: Nov. 06, 2020

    The finished ductile iron pipes are transported to the construction site and inspected in accordance with the standards. Those that do not meet the standards shall not be used and be marked and processed in time. The pipeline installation can be carried out after the construction is completed. During installation, handle with care to avoid falling or hitting the pipe.

  • What Is the Process of Ductile Iron Pipe?

    Date: Oct. 22, 2020

    Due to the high content of carbon and silicon, nodular cast iron has good fluidity and self-feeding ability like gray cast iron. However, due to the difference in furnace pretreatment process and solidification process, nodular cast iron has a big difference in casting performance compared with gray cast iron, so the casting process is also different.

  • Factors Affecting the Surface Gloss of Ductile Iron Pipes

    Date: Oct. 15, 2020

    The process characteristics of ductile iron pipes are also very prominent and obvious, mainly in two aspects. It is a conversion process of sulfate galvanizing. Through many experiments, we can see that the two chemicals aluminum sulfate and aluminum potassium sulfate on the galvanized layer are very stubborn and want to remove them. It's that simple. Therefore, it will affect the glossiness of the ductile iron pipe. Therefore, during the production process, the masters will consciously remove these two impurities through some solution substances. According to the requirements of the process, the ingredients will be supplemented. Then the ductile iron pipe will be You can easily complete the conversion.

  • Points for Installing Ductile Iron Pipes

    Date: Sep. 27, 2020

    Clean the nozzle: clean up all the debris in the socket.
    Clean the rubber ring and put it on: Wipe clean the adhesives on the rubber ring, bend the rubber ring into a "plum blossom" or "8" shape into the socket groove, and press it along the entire rubber ring with your hand. Or use a rubber hammer to make sure that all parts of the rubber ring are not warped and evenly stuck in the groove.

  • How to Repair the Leaking of Ductile Iron Pipe

    Date: Sep. 14, 2020

    Ductile iron pipes need to add some corresponding spheroidizing agents before casting to make the graphite nodular and reduce stress concentration, so that the pipe has the advantages of high strength, high elongation, impact resistance, corrosion resistance, and good sealing; the inner wall adopts Cement mortar lining, which improves the water delivery environment of the pipeline, increases the water supply capacity, and reduces energy consumption; the nozzle adopts a flexible V interface, and the pipe itself has a larger elongation rate (>10%), which makes the pipeline flexible Better, in buried pipes, the pipe can work together with the soil around the pipe to improve the stress state of the pipe, thereby increasing the reliability of the pipe network.

  • Advantages and Disadvantages of Ductile Iron Pipe

    Date: Aug. 31, 2020

    The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus, and magnesium. Implementation of the standard GB/T13295-2003 ISO2531/2003.
    Ductile cast iron pipes are defined as pipes made from molten iron of No. 18 or above by adding spheroidizing agent and then passing through a high-speed centrifugal casting of a centrifugal nodular cast iron machine.

  • Anti-Corrosion Factors of Ductile Iron Pipe

    Date: Aug. 11, 2020

    Ductile iron pipe is a kind of economical water supply pipe. Now it is very popular. Do you know why the ductile iron pipe is so popular? In fact, it is mainly because of its excellent anti-corrosion performance, good ductility, good sealing effect, and easy installation. The most important thing is that ductile iron pipes are more anti-corrosive. Below, the ductile iron pipe suppliers will give you a simple analysis of why the ductile iron pipes have such superior anti-corrosion performance?

  • Performance of Ductile Iron Pipe

    Date: Jul. 28, 2020

    Ductile iron pipe is a kind of cast iron, an alloy of iron, carbon, and silicon. Graphite in ductile cast iron is in the form of spheroids. Generally, the size of the graphite is 6-7. The quality requires that the spheroidization level of the cast pipe be controlled to be 1-3 (spheroidization rate ≥80%), so the material itself is mechanical The performance has been better improved, with the essence of iron, the performance of steel. The annealed ductile iron pipe has a metallographic structure of ferrite plus a small amount of pearlite, which has better mechanical properties. The ductile iron pipe is mainly called a centrifugal ductile iron pipe.
