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 are the advantages of cast iron pipes?
The ductile iron pipe with flexible joint construction, convenient operation, can improve the efficiency of construction, improve the construction conditions, reduce the construction cost, and most of the rubber ring connection interface, simple operation, can shorten the construction period, reduce the construction cost.
Q:What does "K8" mean in ductile iron pipe grades?
K9 is GB, K10 is specially customized, K8... Strictly speaking, it is not up to standard, standard length, wall thickness and so on.. Many workshops, grades of factory products, such as K9, standard length 6.15M, K8 is 6M, wall thickness from the beginning of DN100, are thin on the point.
Q:How can the ductile iron pipe be tested?
The pipeline of water supply pipeline in winter pressure test, must have the corresponding prevention measures, antifreeze, then should give water pipes in the filling should be appropriate in some high, then the protective material for a little more to the interface covered.
Q:Some questions about the bearing capacity of nodular cast iron pipes!
The minimum tensile strength of ductile iron is 400MPa, and the stresses can be calculated according to the wall thickness, diameter and safety factor.
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
The cost is low, the construction cost is low, and the schedule is fast. Such as PVC, PE double wall corrugated pipes, etc..
Q:How much is a ductile iron pipe dn400?
Ductile iron pipe nominal diameter is 80 ~ 2200 mm, compared with grey cast iron, high strength, good toughness, thin wall metal, less dosage, and can withstand high pressure, effective length of 5 meters, 6 meters and 8 meters; according to the different thickness of P, G two. It is the development direction of cast iron pipe.
Q:General cast iron prices now
Regular cast iron prices now range between 5000 and 8000.Ductile iron is a kind of high strength cast iron material developed in 50s twentieth Century, its comprehensive performance is close to the steel, it is based on its excellent performance, has been successfully used in casting complex stress, strength, toughness and wear resistance requirements of the higher parts. Nodular cast iron has developed rapidly to be second only to grey cast iron and widely used as cast iron material. The so-called "iron instead of steel", mainly refers to ductile iron.
Q:How can the ductile iron pipes be treated with corrosion protection?
Cement mortar lining + special coatingThe internal corrosion prevention measures are suitable for pipes conveying sewage, and the corrosion resistance of lining can be improved.
Q:What is the minimum pipe diameter of cast iron pipe?
Nominal diameter of continuous grey cast iron pipe is 75~1200 mm, minimum 75 mm, maximum 1200 mm.
Q:Ductile iron pipe connection mode
Main points of installation: (1) clean the pipe mouth: clean all the sundries in the mouth. Second, clean aprons, aprons on the adhesive material on the apron: clean up, put the ring bending "plum blossom" or "8" shaped into a socket groove, and hand along the entire ring press again, or with a rubber hammer, to ensure that each part of the warping apron is not twisted, evenly the card in the slot.
