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:How much is a ductile iron pipe dn400?
Ductile iron pipe nominal diameter is 80 ~ 2200 mm, compared with grey cast iron, high strength, good toughness, thin wall metal, less dosage, and can withstand high pressure, effective length of 5 meters, 6 meters and 8 meters; according to the different thickness of P, G two. It is the development direction of cast iron pipe.
Q:What is ductile iron pipe?
Ductile cast iron is defined using the above number 18 by adding nodulizer, after centrifugal ductile cast iron machine centrifugal cast pipe, ductile iron pipe (called [span]Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..
Q:General cast iron prices now
Hello friends, Tianjin is in Shandong Qingdao 6500 7300 yuan / ton to 7100 yuan a ton of Zhejiang 7500 to 9000 yuan a ton, this is a great relationship, and the production of raw materials, for reference only, we are ductile casting manufacturers, the information can not say 100% accurate but can reference.
Q:The difference between ductile iron pipe and steel pipe used in pipe jacking
The casting processes of nodular cast iron pipes are continuous casting, hot die casting and water-cooled centrifugal casting, in which water cooling is the most advanced process in the world,
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:How many degrees can the ductile iron pipe be each?
Minimum tensile strength: 420/Mpa, minimum yield strength: 300/Mpa, minimum elongation 7%.
Q:How to analyze and judge the quality of ductile iron pipe
On the quality of single pipe can analyze it from the surface is sand type and water cooled pipes, K8 pipe is different from Shanxi root nature is that the proportion of grade K9 cement and cast iron pipe and the K8 pipe are different, there is no national standard and non standard, no K8 tube, only is the production plant in order to obtain more profits, the dealer is not up to the national standard K9 grade pipe called K8 grade ductile pipe, K9 pipe cement weighs about 1/5 weight of the pipe, but is played in the role of anti-corrosion, the so-called K8 class water mud proportion some manufacturers terrifying 3/4 or 3/5, as the water supply pipe 3/5 or no personally think that two of the proportion of the tube is no problem
Q:DN1800 can the length of ductile iron pipes be several meters? What is the total weight?
In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the cast iron pipes, ductile iron pipes and finished product libraries can be better improved, with the nature of iron and the properties of steel.
Q:The difference between flexible joint cast iron pipe and flexible anti-seismic cast iron pipe
Nodular cast iron pipes and fittings technical manual PDF download Fan Yingjun handsome date: Author: fan manufacturing technology, in January 2006, this book introduces the ductile iron pipe interface form, quality standard, installation technology and special use of ductile cast iron pipe and other content, lists all the technical parameters for ductile iron pipes, pipe fittings interface in order to facilitate the readers to use and accessories
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.
