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:Disadvantages of ductile iron pipes
The strength of nodular cast iron is comparable to that of cast steel. Ductile iron has higher yield strength, the lowest yield strength is 40K, while the yield strength of cast steel is only 36k.
Q:Deep well spiral iron pipe, or ductile iron tube?
In the ferrite and pearlite matrix on the distribution of a certain number of spheroidal graphite, according to the nominal diameter and the elongation of different microstructure of ferrite and pearlite in different proportions of small caliber pearlite percentage is generally not more than 20%, large diameter of the general control in about 25%.
Q:Is ductile iron pipe breakable?
The ductile iron pipe has many uses in our city construction, for our city water supply, gas supply and so on. But ductile iron pipes are also very useful in sewage disposal. As we all know, ductile iron pipe has many excellent properties, such as high strength, corrosion resistance, high pressure resistance, low accident rate, long service life and Gao Yanshen rate. It is an excellent water supply pipe.
Q:An urban infrastructure construction, water supply pipe is ductile iron pipe and PE pipe, thank you
Because the construction of municipal water supply pressure will be relatively large, generally used in the selection of pipe centrifugal ductile iron pipe, he has properties of iron essence and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, ductile iron pipe is mainly used for municipal, industrial and mining enterprises, water supply, gas, oil etc.
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:What is the relationship between the direction of the spigot and the direction of the flow in the ductile iron pipe?
Called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..
Q:Can ductile iron pipes be made into clear tubes?
Of course, you can also use as a pipe, but because of the appearance of cast iron pipe is not very beautiful, but relatively brittle, by external impact or bad insulation cold winter break, so according to your use of the environment to determine.
Q:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
600-3 is pearlite + a small amount of ferrite matrix ductile iron. Pearlite edge region. 10%, center. 70600-3. Two sets of numbers indicating the grades and mechanical properties of nodular cast iron. The former represents the minimum tensile strength
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 kind of valves are commonly used in ductile iron pipes?
You ask the ductile cast iron valves used on no special, because this interface in connection with the valve on the pipe flange is basically, as long as the flange of the valve should be can be used in milling pipe.
