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:The role of chromium in nodular cast iron
Chromium has better strengthening and toughening effect in nodular cast iron. Chromium containing cast iron has the characteristics of high strength, high elongation, high impact value and low hardness.
Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Of different uses, ductile iron pipes are widely used for municipal water supply and drainage, rural drinking water and outdoor fire fighting works; mechanism cast iron pipes are mainly used in the city.
Q:Method for cutting large diameter ductile iron pipe
When the oxygen and acetylene volume ratio is greater than 1.2, is formed. As more oxygen, burning, the flame length is shortened obviously, cone tapered inner flame almost disappeared, and a strong desire. Making due to oxygen, the oxidation of metal, so are not widely used, only used for welding of brass, to prevent evaporation of zinc.
Q:How can the ductile iron pipe depress the elbow so as to prevent it from being opened?
Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metals and plastics.
Q:Is the spigot and socket connection of the ductile iron tube reversed?
The whole process is formed by the radial compression of the pipe blank and the stretching process of the branch pipe. Different from the hydraulic bulging three, the metal of the three way joint pipe is compensated by the radial movement of the tube blank, so it is also called radial compensation process.
Q:Why is the sound speed of nodular cast iron lowered after heat treatment?
After the heat treatment, the microstructure of the material changes, the graphite changes, eliminating the internal stress of molecules, thus slowing down the speed.
Q:Nodular cast iron, heat treatment process and so on
High temperature graphitization annealing was adopted to eliminate the chill, and 900-950 and 2-4H obtained ferrite structure
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 many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?
The metal mould is ok! The surface quality of the casting is better than that of the sand mold. But later heat treatment is needed.
Q:Is the cast iron pipe buried in need of antiseptic treatment? What kind of anticorrosive materials are used?
It must be antiseptic. Usually hot asphalt brush painted two times, winding glass fiber cloth two road, cross construction.
