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:Comparison of C and K grades of ductile iron pipes
The nominal pressure ratio of the C class pipe is lower than that of the K grade tube, and the applied pressure is low.
Q:How can the ductile iron pipe be punched?
Main points: manual hydraulic drilling machine and drilling machine, drilling machine is to rely on human features manually through the drill holes in the pipeline: the need for manpower and time, simple operation and economic benefits; characteristics of the hydraulic drilling machine is through the electric pump or gasoline pump driven drill holes: human, mechanical opening. The need for daily maintenance, high cost. General aperture 300mm can be done by hand drilling machine
Q:Could you tell me how to weld ductile iron parts and steel tubes?
Disk or disk plug connection, it is best to use flange connection. First insert a flange plate on the ductile iron pipe and then screw it with the flange on the weld pipe. But note, because ductile iron pipe material is crisp, and the two connecting flange sealing surface is best all the plane, in order to prevent damage due to uneven iron flange.Material is different, ductile iron pipe is made of ductile iron, seamless steel pipe is made of structural steel. Such as No. 20 steel, No. 35 steel, 16Mn steel and so on. The two is the manufacturing process is also different, ductile iron pipe is generally sand casting molding; seamless steel pipe is made of billet through seamless steel tube mill hot rolling molding.
Q:How to inspect ductile iron pipe fittings?
While the proportion of the so-called K8 class cement pipe and some manufacturers terrifying 3/4 or 3/5, as the water supply pipe 3/5 or no personally think that two of the proportion of the tube is not the problem, the most intuitive way of judging the quality of ductile pipe is cement and iron thickness ratio of thicker tube wall thickness of cement the better the quality, some manufacturers of production pipe, thick wall pipe head cast iron part looks to be thick, but there is also a thin iron pipe, so the judge quality to cut inside, personally think that the highest price of the manufacturer is Jinan steel, Jinan Iron and steel because the pipe quality can reach the national standard K9, the price is also below new, Saint Gobain and other major brands, as the water supply pipe K8 is no problem, but the price and quality for the construction of what importance Stronger.
Q:How can ductile iron pipes be connected to steel tubes?
But pay attention, because ductile iron pipe material is crisp, and the two connecting flange sealing surface is best all the plane, in order to prevent the uneven force and damage to cast iron flange.
Q:Connecting process of ductile iron pipe spigot and socket rubber ring
The material is made of metal rubber. It is a kind of homogeneous elastic porous material. It not only has the elasticity of rubber, but also has excellent characteristics of metal, it can work at -150~800 centigrade temperature. At the same time, it can also bear pressure and within a certain range has dual functions of pressure and seal.
Q:Is the cast iron tube the same as the ductile iron pipe?
According to its manufacturing methods can be divided into: sand, centrifugal pipe, straight pipe, continuous cast iron pipe and sand pipe.According to the material used, it can be divided into gray iron pipe, nodular cast iron pipe and high silicon iron pipe.
Q:How much is the installation of a two degree elbow for ductile iron pipe fittings at 11.25 degrees?
The following is the ductile iron pipe specification and quotation: name of material specifications (KG weight / root unit note DN100 ductile cast iron ductile iron DN150 9552006 meters 14441006 meters 19440006 meters DN250 DN200 ductile cast iron ductile cast iron ductile iron DN300 25506 meters 32339506 meters 40306 meters DN400 DN350 ductile cast iron ductile iron ball 48239506 meters DN450 graphite cast iron ductile iron DN500 57740506 meters 66940506 meters 88241506 meters DN700 DN600 ductile cast iron ductile cast iron ductile iron DN800 112342506 meters 139443006 meters 169006 meters DN1000 DN900 ductile cast iron ductile cast iron ductile iron DN1200 201706 meters to 275806 meters
Q:What are the categories of ductile iron pipe fittings?
The heat pipe trench is in rotational groove tube internal high temperature composite cold water general PE, cohesive force is very strong and do the destructive test will be found with a knife, the pipe made by hot plastic process, lined with PE layer inside the hard to cut down. The injection pipe is a kind of composite pipe formed by injection of PP into the inner part of the groove pipe.
Q:How can the ductile iron pipe be connected to the PE pipe?
Other ways of connecting steel and plastic excessive, one end is PE, and the other end is iron pipe fittings, but not as reliable as flange pressure, different systems pipe connection, it is recommended to use flange connection.
