5.FAQ:
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:How can the ductile iron pipe be punched?
Ductile iron should be drilled, the key is to see how big holes. If it is a small hole, you can consider using a small drill around 5mm to slowly wear the pipe, and then gradually reaming. If the fight is relatively large hole, may according to the aperture required first hit a circle hole, and then use a small chisel chisel down, slowly put the plate again to be trimmed. When drilling, add a little oil to cool the drill bit.
Q:How many kinds of elbow of ductile iron pipe?
You can measure the big money to camber, can call to the manufacturers to build. Seems to have 12.5 and 22.5 degrees, in the first two months we used 22.5 degrees elbow, the drawback is not good pull
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 is the weight of nodular cast iron pipe calculated?
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:Connecting process of ductile iron pipe spigot and socket rubber ring
Rubber seal ring is formed by one or several parts of the cover, fixed in a ring or a washer bearing and another ring or gasket contact or the formation of the labyrinth of narrow gap, to prevent leakage of lubricating oil and foreign matter.
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: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: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 connected to the PE pipe?
Through the conversion of fittings, because different PE pipes and ductile pipe diameter pipe, so name is needed for the step coupling, called Chinese stepped rod joints
Q:Is the cast iron tube the same as the ductile iron pipe?
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.
