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:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
The material can be annealed and the process is simple, that is, heating the workpiece and cooling it naturally. In this way, the hardness of the workpiece can be reduced.
Q:Are ductile iron pipes available for cutting and are there any relevant specifications?
Can be cut, the specification is based on the original specification, just for some engineering needs
Q:Ductile iron and gray iron is what are the advantages and disadvantages of it
Comparison of ductile iron and cast iron (gray iron)Compared with cast iron, ductile iron has an absolute advantage in strength. The tensile strength of ductile iron is 60K, while the tensile strength of cast iron is only 31k. The yield strength of ductile iron is 40K, while the cast iron does not show yield strength, and eventually breaks. The strength to cost ratio of ductile iron is far superior to that of cast iron. Ductile iron is the same as cast iron in corrosion resistance.
Q:What are the meanings of cast iron pipe wall thicknesses LA, A and B respectively?
According to its manufacturing methods can be divided into: sand, centrifugal pipe, straight pipe, continuous cast iron pipe and sand pipe.According to the material used, it can be divided into gray iron pipe, nodular cast iron pipe and high silicon iron pipe.1 、 water supply cast iron pipe:The use of cast iron cast iron water pipe of No. 18 above by adding nodulizer, after centrifugal ductile cast iron pipe by centrifugal casting machine, the performance of ductile iron pipe with nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises water, gas, oil etc.. Water supply pipe is the first choice, with high cost performance.2 、 sand casting centrifugal cast iron pipe:The sand casting centrifugal cast iron pipe is made of gray cast iron. It is suitable for the transportation of pressure water such as water and gas.
Q:What is a graphite cast iron pipe?
Ordinary cast iron consists of gray cast iron and ductile iron, the difference is the carbon in cast iron (graphite) exist, graphite in gray cast iron is in the shape of flake, so the strength and toughness are poor; graphite in shape is spherical, with little on dissevered the matrix. So strong and toughness will be much better.
Q:How can the ductile iron pipe depress the elbow so as to prevent it from being opened?
The elbow is the pipe that changes the direction of the pipe. According to the angle, there are 45 degrees and 90 degrees, 180 degrees, three most commonly used, in addition, according to the project needs, including 60 degrees and other non normal angle elbow.
Q:What are the risks in the process of conveying ductile iron pipes?
Lifting: be careful lifting pipe, don't let the pipe shaking, lifting pipe by wire rope, sling and special sling, wire rope no single, for the protection of pipe coating, rubber or similar materials can be used to wrap up the rope. The use of hook, for the protection of the cement lining layer is not damaged, will hook with rubber or similar material wrapped up, especially in the hoisting of large diameter pipe, will not be fixed in the socket with hook in end strip or pipes.
Q:What are the differences between cast iron pipes W and A?
Type W: combination of both advantages of the connection type A interface has the advantages of high strength and convenient installation, because of the use of W type straight pipe and reduces the material cost and can be coupled with the design structure of the B type pipe is more compact than the A type pipe, saving installation space.
Q:What are the advantages of cast iron pipes?
The ductile iron pipe with flexible joint construction, convenient operation, can improve the efficiency of construction, improve the construction conditions, reduce the construction cost, and most of the rubber ring connection interface, simple operation, can shorten the construction period, reduce the construction cost.
Q:Is the water cast iron pipe 100% for hydrostatic test?
Domestic manufacturers, such as steel group wing ductile iron pipe limited liability company, Xinxing Ductile iron pipes, Saint Gobain pipe is 100% factory test pressure, test pressure in 3.2-5.0MPa according to different specifications.
