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's the function of the cement mortar lining of ductile iron pipes?
You may easily say that this statement is vague and there is no evidence that other manufacturers often do so when promoting other types of lining. However, in order to prove the truth of the above view, we have compiled sufficient examples to demonstrate the reliability of each of these statements from a scientific and logical point of view.We have stated each of these fields and other embedded systems as specious statements. There is only a reasonable conclusion that the cement mortar lining (CML) provides excellent protection for ductile iron pipes and steel tubes.Ductile iron pipe and steel pipe CML CML produces a synergistic effect of the incomparable.
Q:Ductile iron pipes perennial bubbles in the water will rot it
Water supply pipe is the first choice, with high cost performance. Compared with the PE pipe, from the installation time, ductile pipe PE pipe installation is simple and rapid, and after the installation of internal and external pressure bearing better tightness and corrosion resistance; from the point of view, ductile pipe sealing better after installation, but also can improve the corrosion resistance through various anti-corrosion methods;
Q:Is the crankshaft material forged or ductile iron?
Nodular cast iron, cast iron, forged steel crankshaft are used in the three. There are 3 kinds of axes in our company
Q:Can the sealing ring of ductile iron pipe be reused?
It is better not to have used things, easy aging, sealed, the best to use new
Q:What is cast iron pipe, specification for cast iron pipe?
A cast pipe made of cast iron. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings.
Q:How to analyze and judge the quality of ductile iron pipe
The quality of water supply pipe ductile is a topic worthy of discussion, how to judge the quality of the ductile iron pipe, ductile now on the market is all kinds of pipe, a name sand type ductile iron pipe, ductile water-cooling tube, K8 grade K9 grade ductile iron pipe, ductile iron pipe, also the brand is divided into ductile ductile pipe pipe, big brands, and some well-known manufacturers of producing ductile pipe,
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:Can ductile iron pipes be made of flexible waterproof sleeves?
Flexible waterproof casing is suitable for pipeline through the wall in vibration or by strict waterproof requirements of the structures of hardware fittings, general production enterprises according to the Construction Science Research Institute developed S312, 02S404 standard atlas manufacturing. The wall of flexible waterproof casing wall, in case of non concrete should be replaced by concrete walls, and a casing must be solidified on the wall; flexible waterproof casing application widely used in construction, chemical industry, iron and steel, tap water, sewage treatment and other units.
Q:Ductile iron pipe length is generally much
The water-cooled metal ductile iron pipe has a single length of 6 meters, and the current mainstream ductile tubes are water-cooled metal ductile iron pipes.
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.
