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:Is the fire hose capable of using rapid repair joints?
Clear。 Before installation, cleaning work should be carried out, the parts to be cleaned include: socket end, the mouth of the socket, the corner of the socket to the white line should be smooth, no sharp points, so as not to wear aprons when installation.
Q:How can 4 inch ductile iron pipe be connected with 2 inch galvanized pipe?
The hot dip galvanized welded steel pipe galvanized pipe, galvanized pipe by welding without taking anti rusting measures (furnace welding and welding) steel pipe, seamless steel pipe or other metal pipe of the clarinet, process of hot dip galvanizing, the outer coating and galvanized layer to long-term corrosion of the steel pipe after processing.
Q:What does "K8" mean in ductile iron pipe grades?
K9 is GB, K10 is specially customized, K8... Strictly speaking, it is not up to standard, standard length, wall thickness and so on.. Many workshops, grades of factory products, such as K9, standard length 6.15M, K8 is 6M, wall thickness from the beginning of DN100, are thin on the point.
Q:Is ductile iron pipe breakable?
The ductile iron pipe has many uses in our city construction, for our city water supply, gas supply and so on. But ductile iron pipes are also very useful in sewage disposal. As we all know, ductile iron pipe has many excellent properties, such as high strength, corrosion resistance, high pressure resistance, low accident rate, long service life and Gao Yanshen rate. It is an excellent water supply pipe.
Q:Ductile iron pipe joint leakage
After cleaning the pipe mouth, the cf-2000 high efficiency composite waterproof agent is used to seal it, and it will not leak.
Q:What is cast iron pipe?
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.
Q:What effect does magnesium play in nodular cast iron?
Magnesium can be graphite precipitated in spherical form.But the specific mechanism is not clear, and now it is still debated in the academic circles.In addition, magnesium and sulfur generate MgS, which removes S from molten iron, which impedes the formation of spheroidal graphite.Therefore, Mg has two functions to eliminate the influence of S on Nodular Iron and promote the precipitation of graphite in spherical form.
Q:The design uses water supply ductile iron pipe, PE corrosion protection pipe, HDPE pipe, please ask that good? What's the price of the two?
Ductile iron pipes are difficult to make and do not make money, and even easy to lose money, it is not recommended to do, the price can be found on Baidu. DN100 6, about 400 yuan ~500 yuan, DN200,6 about 900 yuan ~1000 yuan, when the market to buy to ask a length. Difficult to do in ductile pipe easily affected by topography (when digging the trenching dug in front of the back of their repair, trouble), vulnerable to local soil effects (such as settlement). Parts connection is not fixed, easy to leak. The advantage is that once the installation is completed, the pressure test is successful and is used for life.
Q:How can the ductile iron pipe elbow be fixed?
Ductile cast iron pipe in the groove pipe connection technology is also called the lathedog connection technology, has become the most liquid and gas pipeline connection technology, although this technology is later than foreign in domestic development time, but because of its advanced technology, domestic market quickly received. Since 1998, it has been developed and applied in just a few years. It has gradually replaced two traditional ways of pipe connection, such as flange and welding. Not only technically more mature, the market is generally recognized, but also by the national laws and regulations actively guide the policy. The application of grooved pipe connection technology makes the complex pipe connection procedure simple, fast and convenient. Took a big step forward in pipeline connection technology.
Q:How long is the service life of the cast iron pipe, and the time of use of ductile iron pipes?
When it comes to the service life of nodular cast iron, its maintenance is essential for its long service life. Then, the focus of the maintenance of ductile iron pipe is to pay special attention to, will affect the long-term use of ductile iron pipes, stable operation of socket, row, etc., we should make efforts to these aspects of the mouth without debris. Make sure that the rubber ring of the ductile iron pipe has been smashed with a rubber hammer, and it is not twisted or twisted, and it is uniformly stuck in the slot. Ductile iron pipe in the maintenance process, because of the pneumatic tube axis is buried into the ground, so in the face of a tilt angle of the time, we must be careful, if the resistance is too large, will not force the excavation, in order to prevent the distortion of the rubber ring.
