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 are the risks in the process of conveying ductile iron pipes?
Transportation: when transporting pipes by car, two or more pieces of wood should be placed on the platform. The tubes are placed on the wood and fixed with wedges. The pipe out of the car parts shall not exceed the length of 1/4 in vitro. When more than one layer of pipe is installed, the direction of the pipe shall be reversed in each layer, and cushion or cushion shall be added between the two layers of pipes. Finally, the wire rope and cushion are fixed firmly. In the process of transportation, check the risk of falling pipe frequently, check whether the stop wedge is loose, slow down when the road is rough or sharp turn.
Q:Advantages and disadvantages of ductile iron pipes
Generally not used in high pressure pipe network (6MPa or more). Because the pipe is relatively bulky, the machine must be used when installing. When the water leak occurs after the test, all the pipes must be dug out, and the pipe can be hoisted to the height of the clamps. The clamps can be installed to prevent leakage.
Q:What new technologies are there for the installation of ductile iron pipes?
Because the new flexible interface mechanism of cast iron drainage pipe pipe in the development of China's relatively short history, compared with other drainage pipes, people know little of the present, with some experience of the author in the construction, the application of the performance, characteristics and engineering, to do some simple introduction.
Q:What if the ductile iron pipe is broken?
Ductile iron pipe rupture can be repaired by using a cast iron defect repair machine, that is, a cast iron defect repair device. However, the general use of iron defects repair equipment can be repaired welding, and will not affect its use. Ductile iron pipes are used for water supply, so if it breaks, it will not be easy to handle. Make sure that the main valve is closed and repaired.
Q:How much is the working pressure of ductile iron pipe used in water supply pipe and how is MPa determined?
Upstairs are positive solutions, but now outdoor buried water pipes are using steel wire mesh skeleton, plastic composite pipe instead of ductile iron pipeThe general pressure grades used for water supply pipes are 1.0MPa and 1.6Mpa
Q:Method for cutting cast iron pipe
Depends on the material and the use of requirements. Ordinary gray iron, if the incision is not strict, such as water pipes. They are all sheared with hydraulic cutting machine, but the incision will not be very smooth. If it is ductile iron, and the incision requirements are high, it can only be used plasma cutting machine. General fittings, if not specifically required, shall not be cut by machining methods.
Q:What is the manufacturing process of ductile iron pipes? Thank you
Ductile iron pipe is a pipe dream of urban water supply, gas pipelines, sets of high strength, good ductility and corrosion resistance strong strength, has the essence of iron, steel, cast iron pipe and steel pipe is a traditional popular replacement products, is a kind of widely used pressure water supply, gas and send pipes. Has the advantages of high strength, good toughness, corrosion resistance and easy device and other excellent characteristics, is the traditional grey iron and steel pipe replacement products popular, has become the preferred data of water supply, gas industry, set high strength, good ductility and corrosion resistance strong strength, has the essence of iron, steel, is the traditional cast iron pipe and steel pipe replacement products under the popular small as you introduce the ductile iron pipe is how to make the.
Q:There are several forms of flexible interfaces for Spigot Cast Iron Pipes
Japan's Kubota ductile mechanical interface, in recent years has been introduced to China. As in the Beijing water pipeline construction from the Miyun reservoir to the Huairou reservoir, the use of a large number of nodular type DN2600mmK mechanical interface of cast iron pipe.The mechanical interface of ductile iron pipe is divided into A and K. The tubes and fittings are made of ductile iron, straight pipes, screws, bolts and rubber rings.The mechanical interface has good sealing performance. When the water pressure reaches 2MPa in the test, there is no leakage. The axial displacement and the angle of folding all reach a high level, but the cost is higher.
Q:Can centrifugal cast iron pipe be galvanized or coated with asphalt which is good for corrosion prevention?
By spraying zinc and epoxy coal tar coating of ductile iron pipe wall (or epoxy resin paint, polyurethane, etc.) wall using Portland cement (or epoxy powder, epoxy, polyurethane, ceramics etc.) wall coating can effectively active substances in soil and the formation of an insoluble zinc salt protection tube, the internal coating can inhibit corrosion of pipe body fluid medium.
Q:What's the difference between cast iron pipe and steel pipe?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
