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:Can ductile iron pipes be made of flexible waterproof sleeves?
The casing can be divided into ordinary casing to be 2-4 cm thick than the pipe to be used and fixed to the wall or plate, and the pipe passes through it. Flexible bushing - between the casing and pipe, with flexible material to seal the sealing effect. Rigid casing - that is, between the casing and pipe with rigid material sealed to achieve sealing effect. Waterproof casing - is the use of the casing of the environment is to prevent liquid leakage or leakage into place (such as the pool, septic tanks, basement, etc.) is on the outer wall of the bushing is not less than 1 times increase waterproof wing, this wall is poured in the casing as a whole, not because of swelling shrinkage factor and crack and leakage.
Q:What's the difference between grey cast iron pipe and ductile iron pipe?
Spheroidal graphite cast iron and ordinary cast iron contain graphite monomer, that is to say, cast iron is a mixture of iron and graphite. The graphite in ordinary cast iron is flaky, and the strength of graphite is very low, so there are many flakes of voids in the cast iron, so the strength of ordinary cast iron is lower and more brittle. Graphite in graphite cast iron is spherical, equivalent to the existence of many spherical voids in cast iron. The effect of spherical voids on the strength of cast iron is much smaller than that of sheet voids, so the strength of nodular cast iron is much higher than that of ordinary cast iron.
Q:What is the use of ductile iron?
Manufacturer of automotive diesel engines are starting from the prolong engine life, particularly cautious about expressing selection of crankshaft material, when the isothermal bainitic ductile iron and high strength in order to increase the power to weight ratio, expand the turbocharger use influence design according to the material, equipped with exhaust turbocharger tube the temperature is increased to 500 to 70. C, in this condition, the oxidation and creep strength become important. Ductile iron, with good properties, is being used instead of gray iron for the exhaust pipe and will further use silicon aluminum alloy ductile iron as the temperature increases.
Q:DN300 what's the price of the ductile iron pipe / the weight and the price of one meter?
Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance.
Q:How to control mortar proportioning in ductile iron pipe cement coating
The mix ratio of cement coated mortar for ductile iron pipes refers to the weight ratio of various raw materials consisting of ductile iron pipes and cement coated mortars.
Q:How can stainless steel pipes and ductile iron pipes be joined?
Or with a gland type expansion joint, by tightening the pressure plate bolts, sealing pipe fittings and pipe wall, so as to achieve sealing, while retractable function
Q:What does ductile iron pipe "ND200" mean?
The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.
Q:Do rigid cement cast iron pipes need cement piers?
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:Are ductile iron pipes available for cutting and are there any relevant specifications?
You can cut, there should be no specification requirements, as long as you can use, in line with the needs of the project can
Q:A tube is used only in ductile iron pipes, isn't it?
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.
