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:Why does the cast iron pipe always run off when testing?
The pipeline is installed, straight section of each pipe will be added pier, concrete pipe, elbow, three links should also have concrete pier, specific installation method according to GB Atlas 03SS515, and the straight pipe to soil, pipeline interface will be exposed, easy to check.
Q:Comparison of ductile iron pipe and spiral steel pipe
Spiral welded pipe: inner wall smooth, welding connection, a small amount of pressure, need additional anti-corrosion
Q:What material is the cutting tool for ductile iron?
They are all hard alloy materials, all of which are CVD coatings, but the products produced by different manufacturers will be very different.
Q:How much is the installation fee of the 400 largest ductile iron pipe?
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:Ductile iron and gray iron is what are the advantages and disadvantages of it
Ductile iron with high strength, gray cast iron wear-resistant, vibration good.This is the reason why large quantities of grey iron are used as gear in imported vehicles.
Q:Does the cast iron pipe need separate corrosion protection?
Ductile iron is characterized by its ease of decay and deformation, so if it is not a particular requirement, there is no need to do it alone
Q:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
Ductile iron castings have been used in almost all major industries. These departments require high strength, plasticity, toughness, wear resistance, and resistance to ductile iron
Q:What is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
Suppose the water flows from east to west, then the pipe mouth is in the East socket at the West
Q:Can the underground cast iron pipes be connected with clamps to form buttress?
The hoop has the advantages of beautiful appearance, convenient operation, strong clamping force, good sealing performance, etc.. Mainly used for connecting and fastening vehicle, ship, diesel engine, gasoline engine, machine tools, fire, and other machinery and equipment, chemical equipment general nylon hose, plastic hose, hose cloth, water interface and seal etc..
Q:What's the difference between cast iron pipe and steel pipe?
Cast iron pipes (Cast, Iron, Pipe), cast cast pipe. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small. According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds. Divided into gray cast iron pipe and nodular cast iron pipe according to different material. According to the interface form, it is divided into flexible interface, flange interface, self anchored interface, rigid interface and so on. Among them, the flexible iron pipes rubber sealing ring; flange interface cast iron pipe flange fixed in the rubber pad, the flange gasket sealing; rigid interface cast iron pipe socket is large, straight pipe is inserted, sealed with cement, this technology has been basically eliminated
