4.FAQ:

    We have organized several common questions for our clientsmay help you sincerely

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.

 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 are the differences between ductile cast iron pipes and centrifugal ductile iron pipes?
Small, thin pipe fittings are usually rolled or continuously cast, and large, thick pipes are usually centrifugally cast. Compared to sand casting, the tissue is compact and homogeneous.
Q:How much pressure can the ductile iron pipe socket meet?
If it is a general installation, you can rest assured, are within the scope of tolerance.
Q:DN300 what's the price of the ductile iron pipe / the weight and the price of one meter?
Ductile iron pipe is a kind of cast iron. It is an alloy of iron, carbon and silicon.
Q:What are the advantages and disadvantages of spheroidal graphite cast iron?
As a substitute for steel, man developed ductile iron in 1949. The carbon content of cast steel is less than 0.3%, while that of cast iron and ductile iron is at least 3%. The low carbon content in cast steels makes the carbon free of graphite free of structural flakes. The natural form of carbon in cast iron is the form of free graphite flakes. In ductile iron, the graphite flakes change into tiny spheres by special treatment. The improved sphere makes ductile iron more superior in physical properties than cast iron or steel. It is the globular microstructure of this kind of carbon that makes ductile iron more ductile and impact resistant, while the thin form of cast iron causes the cast iron to be free of ductility. The best ductility can be obtained by ferrite matrix.
Q:What material is the cutting tool for ductile iron?
With pleasure. If necessary, you can also describe your processing work and so on, I help you analyze, recommend a few corresponding knives to you.
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
The cost is low, the construction cost is low, and the schedule is fast. Such as PVC, PE double wall corrugated pipes, etc..
Q:What if the ductile iron pipe is broken?
Ductile cast iron pipes are broken because of the excessive heat treatment during casting or the lack of proper addition in casting to prevent the proper change of the proper brittleness and cause the rupture to be effective.
Q:How can stainless steel pipes and ductile iron pipes be joined?
Or with a gland type expansion joint, by tightening the pressure plate bolts, sealing pipe fittings and pipe wall, so as to achieve sealing, while retractable function
Q:Can ductile iron pipes be installed outdoors?
Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance. The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better.
Q:Ways of connecting ductile iron pipes
In accordance with the wall thickness or pressure capacity, ductile iron pipe is divided into K8, K9, K10, K11, K12 four class, where the contract does not indicate, according to K9 supply.
