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:Will the cast iron pipes rust?
Qualified ductile iron pipes can be used for more than a hundred years. The main place where rust is easily exposed is where the outer wall meets the soil because of its high humidity and high oxygen content. Qualified anticorrosion can effectively resist rust, its process principle can not give you the details. Although the wall has a long flow of water, but oxygen scarce, compared with the outer wall is not easy to corrosion, but there is cement lining is necessary.
Q:Ductile iron pipe connection mode
The connection mode of ductile iron pipe installation program: clean up the socket socket to clean up on the apron, apron, pipe (tube), Jack in appearance and rubber brush lubricant to push the pipe into socket to check.
Q:Usage of ductile iron pipe expander
Usage of ductile iron pipe expander:1, the expansion device should check its type, specification and piping configuration before installation, must comply with the design requirements.2, the expansion of the inner sleeve should be noted that the direction of the inner sleeve is consistent with the direction of the medium flow. The hinge rotation plane of the hinge type telescopic device should be consistent with the displacement rotation plane.3, the need for "cold tight" expansion device, pre deformation of the auxiliary components should be installed in the pipeline before they can be removed.4, it is strictly prohibited to use telescopic deformation method to adjust the installation of the pipe, so as not to affect the normal function of the telescopic device, reduce the service life and increase the piping, equipment and supporting components of the load.5 、 during installation, welding slag is not allowed to splash to the surface of wave shell, and the wave shell is not allowed to suffer other mechanical damage.6, pipe installation is completed, should be removed as soon as the wave expansion device used for installation and transportation of yellow auxiliary positioning components and fasteners, and according to the design requirements will be transferred to the specified position limiting device, the pipe system has the ability to compensate fully in the environmental conditions.
Q:What are the differences between cast iron pipes W and A?
W type socket cast iron drainage pipe made of stainless steel flexible clamp connection in the construction of the installation; A type cast iron drainage pipe with flexible flange and sealing ring connection in the construction of the installation; B type cast iron drainage pipe comprehensive advantages of W type and A type cast iron drainage pipe, straight pipe part adopts W type bearing mouth of pipe, pipe fittings with double flange structure;
Q:How can the ductile iron pipe be welded?
Welding cast iron is mainly in three aspects: carbon control, stress elimination, structural adjustment. You can choose better welding materials, such as WE777 and other imported welding materials. Crack resistance is very good. In addition, the sewing process can be adopted in the structure to increase the stability of the welding effect. You can learn more about WE777 welding applications.
Q:The role of chromium in nodular cast iron
In order to further understand the mechanism of chromium in ductile iron, the application of electronic scanning and other test means, from chrome crystal structure, crystallization, solidification, heat treatment transformation principle, further study on the mechanism of chromium in ductile iron.
Q:What does "K8" mean in ductile iron pipe grades?
1 ductile iron pipe grade K8, on behalf of the ductile iron 8 grades, K refers to the wall thickness coefficient, the higher the grade, the greater the pressure, the lower the level, the less pressure to bear.2 wall thickness calculation formula: e=K (0.5+0.001DN).
Q:Ductile iron pipe length is generally much
The water-cooled metal ductile iron pipe has a single length of 6 meters, and the current mainstream ductile tubes are water-cooled metal ductile iron pipes.
Q:Principles for the antiseptic treatment of ductile iron pipes
Anti corrosion process of ductile iron pipe:1. asphalt paint coatingBituminous paint coatings are pipes used to carry gas. Preheating the pipe before spraying can improve the adhesion of asphalt paint and accelerate drying.2. cement mortar lining + special coatingThe internal corrosion prevention measures are suitable for pipes conveying sewage, and the corrosion resistance of lining can be improved.3. epoxy coal tar coatingThe epoxy coal tar coating is not only suitable for gas pipelines, but also for sewage pipes. It is a two component coating with a high adhesion and a very smooth surface
Q:How much is the manual installation fee of ductile iron pipes from 100 to 150 per metre?
According to the various connection modes after the installation of artificial fee at =8.7~9.0 yuan (about /M this is pure artificial installation fee, no other costs to calculate, if packet labor costs and construction should be appropriately increased when installed).
