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:Is it better to use steel tubes or ductile iron pipes for water supply?
You need a definite environment to say which kind of pipe is good!1, ductile iron pipe is cheap, corrosion resistance, lack of toughness is poor, not easy to process;
Q:What are the differences between ductile cast iron pipes and centrifugal ductile iron pipes?
Centrifugal casting is a casting method. Ball milling cast iron pipe is a kind of material.
Q:What are the advantages and disadvantages of spheroidal graphite cast iron?
As a substitute for steel, man developed ductile iron in 1949. The carbon content of cast steel is less than 0.3%, while that of cast iron and ductile iron is at least 3%. The low carbon content in cast steels makes the carbon free of graphite free of structural flakes. The natural form of carbon in cast iron is the form of free graphite flakes. In ductile iron, the graphite flakes change into tiny spheres by special treatment. The improved sphere makes ductile iron more superior in physical properties than cast iron or steel. It is the globular microstructure of this kind of carbon that makes ductile iron more ductile and impact resistant, while the thin form of cast iron causes the cast iron to be free of ductility. The best ductility can be obtained by ferrite matrix.
Q:What is the wall thickness of K10 grade dn=400 ductile iron pipe?
Ductile iron pipe, class K10, DN400 theoretical weight table:Grade K10, DN400 ductile iron pipe wall thickness (T):9mm.Nominal diameter (DN) 400mm, its outer diameter (DE) 429mm.The approximate weight (kg) 29.5. of the crown of the socket;Straight part weight per meter (kg) 83.7.Total quality (kg) (length standard 6000mm) 532.Total mass (kg) (standard work length 5000mm) 448.The main characteristics of ductile iron pipes: ductile iron pipe is a kind of cast iron pipe. Having the nature of iron; the properties of steel. Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Q:What's the difference between grey cast iron pipe and ductile iron pipe?
Ductile iron pipe is a kind of casting alloy developed in the late 1940s. It is a kind of spheroidal graphite cast iron which is added into the molten iron by adding inoculant and inoculant. The mechanical properties of spherical graphite, so much more better than that of grey cast iron, cast iron, close to the steel, but the price is lower than steel, and still has many excellent properties of ordinary cast iron, such as good casting, shock absorption, machinability and low notch sensitivity etc.. Therefore, many important mechanical parts, such as crankshaft, connecting rod, gear, valve body and cylinder liner, can be made of ductile iron to save steel and reduce cost.
Q:How can the ductile iron pipe depress the elbow so as to prevent it from being opened?
The elbow is the pipe that changes the direction of the pipe. According to the angle, there are 45 degrees and 90 degrees, 180 degrees, three most commonly used, in addition, according to the project needs, including 60 degrees and other non normal angle elbow.
Q:Why is the sound speed of nodular cast iron lowered after heat treatment?
This may be the material microstructure changes after heat treatment, is generally the pearlite content increased, the available change heat treatment and then check the corresponding microstructure and corresponding measuring sound velocity adjustment, such as annealing, normalizing etc..
Q:How can the ductile iron pipe be welded?
If the hole on the ductile iron pipe, you can use special hoop lined flexible rubber ring, rubber ring and pipe wall coating with rubber ring, glue to be fixed.
Q:How can the three pipes of ductile iron leak?
When the pipe connection of the three water leakage, first of all to see whether it is to do the pipe three links of the manufacturers, pressure did not reach, if it is. It is only the replacement, if not, with cast iron electrode welding, or socket connection half!
Q:What is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
The ductile iron pipe is installed in the direction of the current.
