Product Description:

Ductile Iron Cast Pipe is without any defects compare with tradition casting tech, which has many advantages particularly as follow:

(1) High density. In the "vertical upward casting" process, the melt iron of centre liquid column in center crystallizer is continuously feeding for volume shrinkage caused by condensation tube at outer circumference , which lead to be free of shrinkage porosity.

(2) High purity. When melt iron pouring, the mixed impurities such as gas, dross, sand grain which are lighter than melt iron could be eliminated at furnace mouth, its impossible to enter into the crystallizer through the channel, so the melt iron into the crystallizer is very pure.

(3) Strength with toughness. The cooling speed provided by continuous crystallizer is 30 times than sand casting and 5 times than centrifugal casting, and doesn't produce white iron, the eutectic cell volume of continuous cast iron is one eighth to one tenth compare with traditional cast iron. The density of graphite nodule in ductile iron can reach 300-700 pcs/mm2. Therefore, all reason above improve the strength and toughness of continuous cast iron.

(4) Free machining. The high speed cooling make the hardening phase (such as boride, steadite) not appear like reticular, massive or thick, but diffuse like fish bone and pane in shape, moreover, there are tiny graphite flakes inlaid hardening phase. It's free machining in BrinellHardness the range of 250-300HB. However, the Brinell Hardness of 250 is top limit to common metal materials.

(5) Uniform composition of tube wall. The convection mixing of liquid column caused by marching type drawing in crystallizer make the composition of tube wall well-distributed, and concentration gradient very little.

(6) High productivity. To the wall thickness of tube under 10mm, the speed of continuous casting is 1 meter/min, to the wall thickness of tube under 20mm, the speed of continuous casting is 0.5 meter/min, which is high efficiency that centrifugal or other casting tech couldn't reach.

Q:Can ductile iron pipes be made of flexible waterproof sleeves?
Flexible waterproof casing is suitable for pipeline through the wall in vibration or by strict waterproof requirements of the structures of hardware fittings, general production enterprises according to the Construction Science Research Institute developed S312, 02S404 standard atlas manufacturing. The wall of flexible waterproof casing wall, in case of non concrete should be replaced by concrete walls, and a casing must be solidified on the wall; flexible waterproof casing application widely used in construction, chemical industry, iron and steel, tap water, sewage treatment and other units.
Q:What does ductile iron pipe "K" mean?
K means wall thickness registration, general water supply and drainage, now China uses K9, and some countries in South America, such as Brazil, use K7.The wall is thick =k (DN/1000+0.5), such as K9's DN500 tube, with a wall thickness of =9* (500/1000+0.5) =9mm
Q:How can the connection of ductile iron pipe elbow be convenient for connecting?
Ductile cast iron pipe in the groove pipe connection technology is also called the lathedog connection technology, has become the most liquid and gas pipeline connection technology, although this technology is later than foreign in domestic development time, but because of its advanced technology, domestic market quickly received. Since 1998, it has been developed and applied in just a few years. It has gradually replaced two traditional ways of pipe connection, such as flange and welding. Not only technically more mature, the market is generally recognized, but also by the national laws and regulations actively guide the policy. The application of grooved pipe connection technology makes the complex pipe connection procedure simple, fast and convenient. Took a big step forward in pipeline connection technology.
Q:Disadvantages of ductile iron pipes
The strength of nodular cast iron is comparable to that of cast steel. Ductile iron has higher yield strength, the lowest yield strength is 40K, while the yield strength of cast steel is only 36k.
Q:How many degrees can the ductile iron pipe be each?
Minimum tensile strength: 420/Mpa, minimum yield strength: 300/Mpa, minimum elongation 7%.
Q:The design uses water supply ductile iron pipe, PE corrosion protection pipe, HDPE pipe, please ask that good? What's the price of the two?
PE pipe is hot melt connection (with thick wall smooth type, don't use the wavy), has the advantages of convenient connection, not affected by terrain, but should pay attention to cold and rain when try not to do, otherwise easily lead to cracks or Water Leakage interface touch interface. The disadvantage is not pressure, heavy machinery on the flat, but the problem is not, as long as the water does not leak, do not need to redo. Also, PE price volatility is relatively large, the size of the price difference is relatively large, a few more runs to ask the price.
Q:What is the K9 standard pressure for ductile iron pipes?
Ductile iron pipe is a kind of cast iron. It is an alloy of iron, carbon and silicon. Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance.
Q:Deep well spiral iron pipe, or ductile iron tube?
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.. 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 pressure bearing better tightness and corrosion resistance; from the point of view, ductile pipe sealing better after installation, but also can improve the corrosion resistance of corrosion protection through a variety of means; 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 main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. The inner wall of zinc spray, anti-corrosion materials such as cement mortar.
Q:A tube is used only in ductile iron pipes, isn't it?
Ductile weakness: ductile cast iron pipes connected by human factors such as the operation level of responsibility, influence, construction not convenient. The advantages of PE PE PE pipe has good corrosion resistance and its anti inorganic performance than that of the metal pipe is much stronger in the buried without corrosion, construction convenient. Small diameter PE pipe in the price performance ratio is better than that of steel and ductile iron.PE tube have disadvantages: benzene, gasoline, carbon tetrachloride and other organic solvents have certain effect on pe. If the organic solvent is infiltrated into the polyethylene, the swelling will occur, and its physical properties will be decreased. Its pressure resistance and temperature resistance are poor.
Q:Is there a kind of pipe called lined ductile iron pipe? Seeking manufacturers?
Yes, ductile pipe is divided into two kinds, one is the ductile cast iron pipe pipe socket (socket ductile pipe), which is mainly used for water supply system, namely the fire water, because of ductile iron pipe with pressure, 10kg, 12kg, 16kg. Pressure small price, a few cheaper, because pure in the production process of different, 1. sand mill 2. metal water cooling, like water, the basic is 16kg.
