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 is the difference between a PE fire hose and a ductile iron pipe?
Cast iron pipe: cast pipe made of cast iron. 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.
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.
Q:How can the steel plastic composite pipe be connected with the cast iron pipe?
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 is the ductile cast iron pipe
Should not have this conceptI make the ductile iron pipe, haven't heard of this thing only ductile iron pipe, ductile cast iron heard tube
Q:Do ductile iron pipes have inner enamel?
If the market supply is indeed difficult, can be done by the owners, Design Institute of supplier relationship; if the design institute requires it to provide products can persist in wilfully and arbitrarily, the available information (if the market can not supply, design a hair ah).
Q:Usage of ductile iron pipe expander
Ductile iron expansion is mainly provided with large flexible, easy installation, the product main material for nodular cast iron, nodular cast iron is mainly through spheroidization and inoculation by spherical graphite, effectively improve the mechanical properties of cast iron, especially the plasticity and toughness increased, resulting in higher than the strength of carbon steel. The material mainly has high strength of plasticity and toughness, and its development at home and abroad is very fast, the output has exceeded cast steel and malleable cast iron, become second only to gray cast iron casting alloy material. Spheroidal graphite is obtained by spheroidizing and inoculation of nodular cast iron. It can effectively improve the mechanical properties of cast iron, especially improve the plasticity and toughness, so as to obtain higher strength than carbon steel.
Q:How many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?
The metal mould is ok! The surface quality of the casting is better than that of the sand mold. But later heat treatment is needed.
Q:Deep well spiral iron pipe, or ductile iron tube?
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:Can cast iron pipes not be used for domestic water supply and drainage?
Cast iron pipes are mostly used in fire fighting, fire hydrant water supply and indoor water supply. Plastic pipes are used in general and high water riser pipes are made of plastic steel composite pipes
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.
