Q:Ductile iron pipes perennial bubbles in the water will rot it
From the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve greater runoff; from the installation and maintenance cost, ductile pipe have more favorable price. The inner wall of zinc spray, anti-corrosion materials such as cement mortar, ductile iron pipe perennial bubbles in the water will not be rotten.
Q:Disadvantages of ductile iron pipes
Compared with cast iron, ductile iron has an absolute advantage in strength. The tensile strength of ductile iron is 60K, while the tensile strength of cast iron is only 31k. The yield strength of ductile iron is 40K, while the cast iron does not show yield strength, and eventually breaks. The strength to cost ratio of ductile iron is far superior to that of cast iron.
Q:What is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
The use of cast iron by adding more than 18 nodularizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
Q:How much is the installation of cast iron pipe drainage 1 meters?
Ductile iron pipes mainly called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Q:What is the exterior anticorrosion of nodular cast iron pipes?
According to the national standard GB/T13295-2008, external corrosion prevention technology of ductile cast iron pipe is coated with asphalt paint, spraying zinc, widely used in domestic manufacturers is spraying zinc spraying asphalt layers corrosion, zinc layer thickness: 130 grams / square meters, the thickness of asphalt 75Um.
Q:Method for cutting cast iron pipe
Depends on the material and the use of requirements. Ordinary gray iron, if the incision is not strict, such as water pipes. They are all sheared with hydraulic cutting machine, but the incision will not be very smooth. If it is ductile iron, and the incision requirements are high, it can only be used plasma cutting machine. General fittings, if not specifically required, shall not be cut by machining methods.
Q:Fire water supply network adopts ductile iron pipe, the test pressure should be no more than MPa
To your selected fire pump highest lift 1.5 times to suppress, generally not more than 1.6MPa, if the use of ductile iron pipe, test pressure according to 2MPa to suppress.
Q:Does the cast iron have size 250? What's the performance?
1, cast iron because of low melting point, casting process performance is good, because it has been widely used.2, the relative gray iron ductile iron, have higher tensile strength and impact toughness, which has better mechanical performance.
Q:What is the excavation width of ductile iron pipes with diameters greater than 1400?
Because of differences in depth and soil properties, the excavation width is differentUsually to ensure that the width of bottom surface on both sides of the 600 1400+ manual operation. (such a large pipe flange bolt, the tool is not easy to expand, so the need for manual operation. So wide)
Q:What is the use of ductile iron?
Ductile iron is used as a conduit at the beginning. Iron pipes and fittings are mostly produced by major industrial countries. Their manufacture, design and use are in line with national standards and international standards and procedures (I502531). As far as water and other liquids are concerned, it has long been proved that ductile iron pipes are superior to gray iron pipes. The main reason for this change is the combination of strength and toughness of Ferritic Ductile Iron, which makes the pipes made of this material subject to high operating pressures and can be readily loaded and laid during laying. A gas pipeline must be able to withstand multiple use requirements, which stand near the pipeline excavation and municipal engineering construction and transportation, where the ball iron pipes with high strength, high performance and simple installation and connection technology has proved that this material selection is decisive.
