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:Does the cast iron have size 250? What's the performance?
You should be the casting grade or material, if it is ductile iron, said generally between QT400-15 or QT700-2 different indicators, said in front of the tensile strength, the elongation rate refers to the back, China is now the lowest grade of nodular cast iron material is QT400-15, such as QT250.In addition, the number 250 you refer to may also be a code name for ductile iron parts, such as 200, 300, etc., which are manufactured by the factory as required by the project.Gray iron, which has a 250 brand, is generally referred to as HT250, but it is not ductile iron.The machine on the ductile iron and gray iron are used, but generally not made of grey cast iron gear
Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Of different uses, ductile iron pipes are widely used for municipal water supply and drainage, rural drinking water and outdoor fire fighting works; mechanism cast iron pipes are mainly used in the city.
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:What do ductile iron pipes need to connect with three? Can I contact it directly?
Old craft1. dozen to lead lead; cut into strips, with a file play in the interface2. use expanded cement with asbestos3 use the asphalt
Q:DN300 what's the price of the ductile iron pipe / the weight and the price of one meter?
The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better.
Q:How much is the installation cost of the ductile iron tube?
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 are the specifications for the installation of water ball iron pipes?
Ductile cast iron pipe is characterized by mild, high, thin wall, pressure resistance, impact resistance, corrosion resistance, seismic resistance and other properties. The flexible interface is used for the pipeline interface, and there is a certain elongation and deflection angle. The utility model has the advantages of the raw iron pipe and the steel pipe material, and avoids the defects of iron and steel.
Q:Ductile iron and gray iron is what are the advantages and disadvantages of it
Comparison of nodular cast iron and cast steelThe 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. In most municipal applications, such as water, brine, steam, ductile iron has more corrosion resistance and oxidation resistance than cast steel. Because of the spheroidal graphite microstructure of nodular cast iron, nodular cast iron is superior to cast steel in reducing vibration ability, so it is more beneficial to reduce stress. An important reason for choosing ductile iron is that ductile iron costs less than cast steel. The low cost of ductile iron makes this material more popular, more efficient and less costly for ductile iron.
Q:QT400-10 nodular cast iron requires hardness of HRC47~51. Why can't quench hardness be reached?
Quenching temperature: when the silicon content of nodular cast iron is 2.0-3.0%, the quenching temperature is 860-900 DEG C, the silicon content is low, and the upper limit is taken when the lower limit is high.2. holding time: because of the consideration of diffusion graphite cast iron, alloy steel is therefore the holding time, holding time longer than carbon steel.3. oil quenching.
Q:Ductile iron pipe length is generally much
The spheroidal graphite tube of hot film casting process is generally a single branch with a length of 8 meters. The ductile iron pipes produced by this process are usually large caliber pipes. For example, DN1000 or more.
