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:What does ductile iron pipe "K" mean?
K means wall thickness registration, general water supply and drainage, now China uses K9, and some countries in South America, such as Brazil, use K7.The wall is thick =k (DN/1000+0.5), such as K9's DN500 tube, with a wall thickness of =9* (500/1000+0.5) =9mm
Q:The role of chromium in nodular cast iron
In the bending fatigue test of crankshaft, it is also found that the chromium containing cast nodular iron crankshaft has the characteristics of large ultimate bending moment, high safety factor, overload duration, high strength and small deformation.
Q:Which is good for water polo cast iron pipe steel pipe?
Flexible seamless steel pipe is good toughness, good processing, better than ductile iron corrosion resistance, the price is slightly higher;
Q:Disadvantages of ductile iron pipes
Compared with cast iron, ductile iron has an absolute advantage in strength. The tensile strength of ductile iron is 60K, while the tensile strength of cast iron is only 31k. The yield strength of ductile iron is 40K, while the cast iron does not show yield strength, and eventually breaks. The strength to cost ratio of ductile iron is far superior to that of cast iron.
Q:How can the internal and external walls of ductile iron pipes be protected from corrosion?
Inner wall cement anticorrosive exterior wall asphalt anticorrosion
Q:What quota can be used for the installation of DN300 ductile iron pipes?
Ductile iron quota, to see what works, such as the use of ductile cast iron bridge, to see the river length, through traffic, perennial water level to determine the ductile iron pipe length, diameter and number;
Q:Can ductile iron be welded? Is weldability comparable to gray iron?
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.
Q:How to control mortar proportioning in ductile iron pipe cement coating
The mix ratio of cement coated mortar for ductile iron pipes refers to the weight ratio of various raw materials consisting of ductile iron pipes and cement coated mortars.
Q:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
General use of tensile machines, such as quality management, this aspect should be strictly controlled, otherwise the data is not accurate, do nothing, no one wants
Q:Maximum pipe diameter of ductile iron pipe
Price even if it is not clear, you can consult the ball mill cast iron pipe manufacturers!
