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 is the difference between flexible joint mechanism and seismic cast iron pipe DN100 and ductile iron pipe?
The ball compressive strength of ductile iron pipe is much higher than that of cast iron pipes, buried in the ground, the car is not easy to be crushed.
Q:What material is ductile cast iron 235A?
Nodular cast iron by spheroidization and inoculation by spherical graphite, effectively improve the mechanical properties of cast iron, especially the plasticity and toughness increased, resulting in higher than carbon steel. The strength of nodular cast iron is a kind of high strength cast iron material developed in 50s twentieth Century, its comprehensive performance is close to the steel. It is based on its excellent performance, has been successfully used in casting complex stress, strength, toughness and wear resistance requirements of the higher parts. Ductile iron has been the rapid development of cast iron material for application of gray cast iron, only very widely. The so-called "iron steel", mainly refers to the ductile iron.
Q:What is the relationship between the direction of the spigot and the direction of the flow in the ductile iron pipe?
The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
Q:Luo what effect of ductile cast iron
Chromium can improve the hardness, strength and wear resistance of nodular iron, and increase bainite in bainite ductile iron.
Q:What is ductile iron pipe?
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Execution standard GB/T13295-2003ISO2531/2003
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: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:What does ductile iron pipe "ND200" mean?
The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.
Q:What is cast iron pipe, specification for cast iron pipe?
A cast pipe made of cast iron. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings.
Q:How to properly maintain FRP pipes
It has excellent corrosion resistanceDo not use cathodic protection and other anti-corrosion measures to produce two contamination of water and other media. Long service life of products.
