5.FAQ:
We have organized several common questions for our clients,may help you sincerely:
1.Q: Why would you choose ductile iron pipe rather than other pipe materials?
A:The reasons are obvious for that not only ductile iron pipe possesses the inherent strength and flexibility of ductile 
iron, combined with proven corrosion protection systems, but also the cost savings can be achieved from design to 
installation and commissioning.
2.Q:Why can you guarantee the inner of pipes can’t be corroded?
A: High alumina cement mortar lining and sulphate-resistant cement mortar lining. These two special linings are applicable 
to inner anti-corrosion for sewage pipes, improving resistance to erosion of the sewage components.

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:Ductile iron and gray iron is what are the advantages and disadvantages of it
Ductile iron with high strength, gray cast iron wear-resistant, vibration good.This is the reason why large quantities of grey iron are used as gear in imported vehicles.
Q:The difference between ductile iron pipe and UPVC drain pipe
Centrifugal ductile iron pipe is ideal for urban water supply, gas pipelines, sets of high strength, good ductility and corrosion resistance advantages, performance with nature, iron and steel, is the replacement of the traditional cast iron pipe and common steel pipe renewal;
Q:Is ductile iron pipe breakable?
5, inferior wood surface is easy to produce cracks, because its billet is adobe, Adobe porous, Adobe in the process of cooling due to the role of thermal stress, cracks, after rolling, there are cracks;6, poor drainage tube appearance often pitted phenomenon. Pits is due to groove wear caused by defects in pipe surface irregular uneven. Because of the poor sewer pipe manufacturers to pursue profits, often rolling groove rolling most standard.Ductile iron pipes are broken because of the excessive heat treatment during casting or the lack of proper addition in casting to prevent a change in the proper brittleness and to cause cracking. It is recommended that you used to repair defects of cast iron machine, are currently on the market to sell, but also can ensure welding intact appearance, make your products by quality, but if it is in the use of performance can not meet the effect, especially the pipeline pressure quite big, what methods are of no use that must be re cast as the new.
Q:How can the connection of ductile iron pipe elbow be convenient for connecting?
The groove connecting pipe consists of two categories of products: sealing function of pipe connections with rigid joint, flexible joint, mechanical three and groove flange; the pipe connections transition of elbow, three links, four links, different diameter pipe, blind plate etc..
Q:What are the interface forms of ductile iron pipes? The best drawings are available. Thank you
Because of this interface and the corresponding T sealing aprons can withstand greater deflection angle and greater tolerances, especially suitable for unstable formations and corners.
Q:The difference between spheroidal graphite cast iron pipe and HDPE water supply pipe
As the HDPE pipe is made of hot melt connection, the construction is more difficult, and the installation cost is about 40% higher than that of the nodular cast iron pipe.
Q:Does the cast iron have size 250? What's the performance?
Ductile iron does not have size 250. Ductile iron is the beginning of QT, QT400-15, QT450-10, QT500-7 is the general use of nodular cast iron brand. Nodular cast iron welding can be determined, this should be in some high strength cast iron equipment used more, the tensile strength of normally ductile cast iron welding in welding is higher, is worse than the grey cast iron, it is actually very difficult to distinguish with the naked eye is ductile iron or cast iron the iron in the repair equipment, we usually use WE777 special cast iron electrode universal wide welding, but it is only for maintenance use, the effect is really good, reducing the risk of cracking and high strength welding rod matching to ensure the strength of welding seam.
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
Q:Why is the cast iron tube lined with cement? Under what circumstances are ductile iron pipes lined with cement, and under what circumstances do not have to be lined with cement?
The cement lining protects the water quality, reduces the head loss and improves the service life of the spheroidal graphite pipe. As long as the water delivery hose is used, the cement lining must be used. There is no lining cement for conveying air.
