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:Can the sealing ring of ductile iron pipe be reused?
The sealing ring is hard to install and take off. I have been in this line for six years. I haven't seen it removed. The rubber ring itself is not expensive. It is not necessary to reuse it.
Q:What's the difference between ductile iron pipe and cast iron pipe?
We have to correct now basically all socket ductile iron pipes, because the socket type with a rubber ring, plus a ductile material, buried beneath it when the bearing has a certain flexibility, not because of the deformation and leakage phenomenon. To be used, not Unicom cast iron pipe socket, connection is used similar to the stainless steel hoop hoop sleeve closed.
Q:What are the lubricants for the installation of ductile iron pipes for tap water?
Lubricant used to reduce frictional resistance of friction pairs and to retard wear of lubricating medium.
Q:When the ductile iron pipe is pressed, the three links are always running out. What should be done?
This situation depends on whether the pipeline installation is in place and the apron installation is standard. If there are no other problems, it is recommended to play a cement pier, half a pack of three can be solved.
Q:What is the difference between a cast iron pipe and a ductile iron pipe?
Nodular cast iron has high strength and strong plasticity. The tensile strength of ductile iron is twice that of gray iron, and the yield strength even exceeds that of cast steel.
Q:Do rigid cement cast iron pipes need cement piers?
Ductile iron pipes mainly called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc.. 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 of corrosion protection through a variety of means; from the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve greater runoff; from the installation and maintenance cost, ductile pipe have more favorable price. The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. The inner wall of zinc spray, anti-corrosion materials such as cement mortar.
Q:The difference between cast iron pipe and ductile iron pipe
Cast iron pipes, also known as pig iron pipes, ordinary gray iron. Often used in socket connection, the sealing material is usually cement rigid interface.
Q:How many meters does the cast iron water supply pipe dn150,1 tons?
When pouring added calcium alloy in the flow inlet for graft inoculation, every time after the pouring, need in the mold surface with compressed air spraying a thin layer of dry calcium silicate powder, a centrifuge is composed of upper and lower halves of the closed shell, the supporting cast roller is installed on the bottom of the shell, the mold in front of a ring gear mounted on the housing at the end of the DC motor through the transmission gear direct mold, shell mold through Hugh ends are equipped with sealing ring, the front end of the shell shell installed with half ring a turning cylinder pictophonetic mountain Rae centrifuge under the wheels, so as to make reciprocating motion on the inclined orbit
Q:An urban infrastructure construction, water supply pipe is ductile iron pipe and PE pipe, thank you
From the tightness and corrosion resistance, ductile pipe sealing better after installation, but also can improve the corrosion resistance of corrosion protection through a variety of means; from the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve more runoff large; from the installation and maintenance cost, ductile pipe have more favorable price.
Q:The difference between ductile iron pipe and UPVC drain pipe
UPVC tube or rigid polyvinyl chloride pipe, U-PVC pipe, is a kind of strong corrosion resistance, acid and alkali salt oil medium erosion, light quality, has certain mechanical strength, good hydraulic conditions, convenient installation, but easy to aging, high temperature resistant, but can not withstand the impact, applied to the domestic water system, DN50 pipe connection DN65, using a ring connected with the above.
