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) 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 quota can be used for the installation of DN300 ductile iron pipes?
Ductile iron quota, to see what works, such as the use of ductile cast iron bridge, to see the river length, through traffic, perennial water level to determine the ductile iron pipe length, diameter and number;
Q:Qianwei County ductile iron pipe which tool to use cutting convenience?
Cutting the ductile iron pipe by grinding is grinding and cutting the ductile iron tube continuously by grinding wheel until it breaks. To cut ductile iron pipes by grinding cutting method, the cutting parts should be crossed at first so as to avoid deviation during cutting. Place the drawn ductile iron tube in the cutting machine and fix the ductile iron tube and clamp it with a built-in clamp. Next, start the cutting machine and gradually press the handle of the cutting machine. The grinding wheel cuts into the ductile iron tube until the ductile iron pipe is cut off. When exerting pressure on the handle, do not force too hard at once, otherwise it will cause the grinding wheel to break. In the operation of the machine, the operator must not stand on the side of the grinding wheel, so as to avoid accidents. When the wheel appears in cutting, vibration, shaking, uneven phenomenon, should immediately stop the operation, check whether there is the wheel gap, if damaged, must be promptly replaced, to ensure safety and normal. Good cutting ductile cast iron pipe section, if there is to prevent the use of burrs, can be removed by grinding or machining file.
Q:Water supply pipe is ductile iron, then it's fittings and valves and other parts must be ductile iron?
Ductile iron pipe end rubber ring interface should belong to flexible connection. It should be the way to connect the clamps. Then, the valve is also connected to the card sleeve connection.
Q:Is the crankshaft material forged or ductile iron?
Other crankshafts are not clear about the car crankshaft. These two materials are useful, but the trend is to use ductile iron
Q:How much is the working pressure of ductile iron pipe used in water supply pipe and how is MPa determined?
No, the work pressure is generally 0.4~1.6MPa, but the ultimate test pressure of ductile iron pipes is about 4.0MPa.
Q:Ductile iron pipe is how many years warranty
Ductile iron pipe warranty is unlimited.
Q:Maximum pipe diameter of ductile iron pipe
Price even if it is not clear, you can consult the ball mill cast iron pipe manufacturers!
Q:Ductile iron gears are generally treated without heat treatment
The mechanical properties of ductile iron are equivalent to quenched and tempered steel. The gears made of ductile iron can be quenched or tempered by high temperature + surface quenching, that is, quenching and tempering treatment + surface hardening.
Q:Ways of connecting ductile iron pipes
In accordance with the wall thickness or pressure capacity, ductile iron pipe is divided into K8, K9, K10, K11, K12 four class, where the contract does not indicate, according to K9 supply.
Q:What is a slide in type T flexible interface?
As long as the socket is inserted into the slot, the installation is quick, labor-saving and airtight, and what is good is also good
