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 is the use of ductile iron?
As far as the tonnage is concerned, the automotive industry is the second largest producer of ductile iron castings, with the largest number of them. Ductile iron is used in three main parts of automobiles: (1) power source, engine parts; (2) power transmission of a gear train, gears and bushings; (3) vehicle suspension, brakes and steering gear. The power source is subjected to continuous change of the crankshaft bending, torsion and shear load, and in its service life, to one billion cycles of car design engineers early in the 19152 years that the processing method for magnesium found in four years later, immediately consider the possibility of using ductile iron. Almost all crankshafts of Ford motor are made of this material. Most gasoline engines in the world are fitted with ductile iron crankshafts instead of forged steel crankshafts, which are considered a typical example of value engineering.
Q:What do ductile iron pipes need to connect with three? Can I contact it directly?
Because the interface material used in the old process is poisonous, especially in the water supply pipeline, environmental protection requires a new process now
Q:DN300 what's the price of the ductile iron pipe / the weight and the price of one meter?
The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better.
Q:Is nodular cast iron pipe filled with Yau Ma Tei?
In many areas of our country, ductile iron pipe in the middle and small diameter to tube connected with the tube, the bearing type or flange interface method; ductile iron, angle limit must be allowed better seismic performance and sealing performance.
Q:If the ductile iron pipe is broken, can we use rush repair?
These specifications are also based on the outer diameter of the tube. In daily life, we may also encounter a pipeline rupture, or when it is on the road to repair, excavator accidentally hit PE, PPR water supply and drainage pipeline, as long as a little, can be used to repair the pipeline repair section.
Q:Does centrifugal cast iron pipe work well with lining cement? Will it scale and breed bacteria?
From the centrifugal ductile cast iron pipe with cement production process to analysis, the most core pipe by centrifugal molding, concrete water cement ratio, the centrifugal force, the coarse aggregate to the outer wall of the pipe and the pipe inside; because of fine aggregate and water removal, strength and wear resistance variation. When the inner wall of the pipe by long-term washing and soaking water, and inner wall wear and erosion, as the roughness increases, head loss increases, you will need to increase the pump lift, and operation cost for power consumption increases, also greatly increased.
Q:The design uses water supply ductile iron pipe, PE corrosion protection pipe, HDPE pipe, please ask that good? What's the price of the two?
Now the mainstream is PE pipe, ductile iron pipe has been going out.
Q:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
Heavy thermal and mechanical shock, high temperature or low temperature, corrosion resistance and dimensional stability. To meet these changes in use conditions, ductile iron is available in many grades, providing a wide range of mechanical and physical properties.
Q:How to choose a ductile cast iron pipe with guaranteed quality
1, first of all choose the regular manufacturers of ductile iron pipe products.2, the choice of ductile iron pipe, should be based on the specific circumstances of the construction site, select the pipe and fittings corresponding to the form of interface.3, rubber rings recommend the use of three yuan ethylene propylene rubber ring and so on.4, listen to the voice, knocking the iron: short duration. The iron ball: crisp sound, echo, short duration5, the cutting surface is gray: gray, shiny surface seems very dark, very rough. Ductile iron: gray, gray luster is bright, like gray surface roughness.
Q:What is the exterior anticorrosion of nodular cast iron pipes?
Spraying anti-corrosion paint, usually first spray a anticorrosive paint, and then primer 2, paint 2!
