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:What material is ductile cast iron 235A?
Ductile iron is a pig iron
Q:What are the advantages of cast iron pipes?
The cast iron pipe has good sealing performance and is not easy to leak. It can reduce the leakage rate of the pipe network and reduce the daily maintenance cost of the pipe network
Q:Advantages and disadvantages of ductile iron pipes?
Ductile iron pipes are widely used for municipal water supply and drainage, rural drinking water and outdoor fire fighting works; mechanisms; cast iron pipes; main use; municipal high water drainage.
Q:What material is the cutting tool for ductile iron?
The tool manufacturers so much, such as: Santak, Kenna, widia, Dai Jie, Walter, MITSUBISHI, Toshiba, ISCA, TaeguTec, Zhuzhou, each of the grades are not the same. But according to your specific processing workpiece and processing time and precision requirements, can choose the most suitable tool.
Q:What's the difference between ductile iron pipe and cast iron pipe?
Ductile iron pipe is based on cast iron, changed some of the characteristics of the structure of iron, so that it has become a lot of toughness, than the cast iron pipe is too brittle shortcomings much better, the tensile strength of the pipe bending strength greatly improved. The sealing material used in the socket interface is rubber ring.
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:How much is the installation fee of the 400 largest ductile iron pipe?
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.
Q:What is the manufacturing process of ductile iron pipes? Thank you
Ductile iron pipe is a pipe dream of urban water supply, gas pipelines, sets of high strength, good ductility and corrosion resistance strong strength, has the essence of iron, steel, cast iron pipe and steel pipe is a traditional popular replacement products, is a kind of widely used pressure water supply, gas and send pipes. Has the advantages of high strength, good toughness, corrosion resistance and easy device and other excellent characteristics, is the traditional grey iron and steel pipe replacement products popular, has become the preferred data of water supply, gas industry, set high strength, good ductility and corrosion resistance strong strength, has the essence of iron, steel, is the traditional cast iron pipe and steel pipe replacement products under the popular small as you introduce the ductile iron pipe is how to make the.
Q:Which is better, ductile iron pipe and spray plastic pipe?
Ductile iron pipe corrosion resistance, strength, it is said that the Ming Dynasty ordinary cast iron works now, and now has a new type of dedicated, can be used, construction becomes very convenient, ductile iron pipe has no effect on water quality. Plastic sprayed steel pipe is a new type of pipeline with higher price.
Q:How to choose a ductile cast iron pipe with guaranteed quality
1, first of all choose the regular manufacturers of ductile iron pipe products.2, the choice of ductile iron pipe, should be based on the specific circumstances of the construction site, select the pipe and fittings corresponding to the form of interface.3, rubber rings recommend the use of three yuan ethylene propylene rubber ring and so on.4, listen to the voice, knocking the iron: short duration. The iron ball: crisp sound, echo, short duration5, the cutting surface is gray: gray, shiny surface seems very dark, very rough. Ductile iron: gray, gray luster is bright, like gray surface roughness.
