We have organized several common questions for our clients,may help you sincerely:
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.
 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 pipe can be used to replace the cast iron pipe in the water supply? Thank you
You are mistaken in concept. The cast iron pipe is the sort of connection method. The ductile iron pipe is classified according to the material.
Q:Does the cast iron pipe need separate corrosion protection?
Ductile iron is characterized by its ease of decay and deformation, so if it is not a particular requirement, there is no need to do it alone
Q:How much water seepage is allowed in the water pressure test for water hose DN300?
The main control parameters of ductile iron pipes are nominal diameter, working pressure, connection mode, etc.. Light, high, thin wall, pressure resistance, shock resistance, corrosion resistance, earthquake resistance and other properties. The flexible interface is used for the pipeline interface, and there is a certain elongation and deflection angle. He has the advantages of raw iron pipes and steel pipes, avoiding the defects of iron and steel.
Q:Ductile iron pipe is how many years warranty
In the ferrite and pearlite matrix on the distribution of a certain number of spheroidal graphite, according to the nominal diameter and the elongation of different microstructure of ferrite and pearlite in different proportions of small caliber pearlite percentage is generally not more than 20%, large diameter of the general control in about 25%.
Q:What are the specifications of cast iron pipes?
The nominal diameter of the continuous grey cast iron pipe is 75~1200 mm. It adopts the form of socket type or flange disk interface. It can be divided into two kinds of flexible interface and rigid interface according to function. The length of the straight pipe is 4 meters, 5 meters and 6 meters. According to the wall thickness, LA, A and B are divided into three grades. The nominal diameter of the centrifugal cast iron pipe of the sand mould is 200~1000 mm, the effective length is 5 meters and 6 meters. According to the wall thickness, it is divided into two grades: P and G. High strength, good toughness, thin tube wall, little metal consumption, and can bear higher pressure,
Q:Ductile iron pipe length is generally much
The spheroidal graphite tube of hot film casting process is generally a single branch with a length of 8 meters. The ductile iron pipes produced by this process are usually large caliber pipes. For example, DN1000 or more.
Q:The benefits of ductile iron castings
Its performance is close to carbon steel, but it has good casting performance, easy molding, better machinability than cast steel, better heat resistance, corrosion resistance and wear resistance than steel. And a very important one: cheap.
Q:Ductile cast iron can replace copper sleeve
Although the ductile cast iron with lubrication, but no lubrication or copper sleeve, Rongchang graphite copper sleeve, with self lubrication with high strength copper alloy (CuZn25Al5, CuZn24Al6Fe3Mn4) as the basic material, according to the use conditions according to a certain proportion in the work surface processing hole and fill in the solid lubricant, high strength copper alloy provide a high bearing capacity and solid lubricant can form low friction.
Q:What is the excavation width of ductile iron pipes with diameters greater than 1400?
When the condition does not allow enough slope, it is necessary to do wall protection and other means to ensure safetyRemind me, such a big pipe, dig deep in two ways. One is the depth diameter (range at the junction of 1.6 m in length and 500 for manholes and operation. The lower bolt assembly when) there is a depth diameter plus 500. and then in the trench laying branch the pier, installed after the fine stone tamped backfill.Can also be buried directly with the pipe diameter, and then put into the assembly. This method requires a large space on the ground, otherwise, the volume is too large after assembly, weight is too heavy, may cause damage to the pipeline and personnel injuries
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.
