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:How much is a ductile iron pipe dn400?
High quality cast iron ductile iron pipe with low phosphorus and low sulfur iron making production of blast furnace, according to the current international advanced centrifugal casting, annealing process, water-cooled metal type centrifugal pipe casting machine casting, after annealing, socket dressing, pressure test, internal lining layer of cement, cement treated lining, water and health cement lining, outer wall coated with asphalt paint, asphalt paint baking, socket antirust processing, spray marks and other procedures for the packaging, with high strength, high elongation, corrosion resistance of a body strong as iron.
Q:What is the relationship between continuous cast iron pipe and ductile iron pipe?
In general, the continuous cast iron pipe is the continuous casting of gray cast iron pipe, while the centrifugal cast iron pipe is centrifugal ductile iron pipe. Of course, you have to be hard, just to make continuous ductile iron pipes, that's what you want.
Q:How long does the cast iron pipe of indoor direct buried sewage need to be examined?
UPVC, also called hard PVC, is an amorphous thermoplastic resin made by polymerization of vinyl chloride monomer, with certain additives (such as stabilizers, lubricants, fillers, etc.). In addition to additives, the method of blending with other resins is also applied to make it have obvious practical value. These resins are CPVC, PE, ABS, EVA, MBS and so on. UPVC has high melt viscosity and poor flowability. Even if the pressure and melt temperature are increased, the fluidity is not changed. In addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the molding temperature range is very narrow. It is a difficult material to be formed.
Q:What are the meanings of cast iron pipe wall thicknesses LA, A and B respectively?
Cast iron pipes (Cast, Iron, Pipe), cast cast pipe. 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.
Q:What material is the cutting tool for ductile iron?
They are all hard alloy materials, all of which are CVD coatings, but the products produced by different manufacturers will be very different.
Q:Is there a kind of pipe called lined ductile iron pipe? Seeking manufacturers?
The 10kg pressure ball tube is also used as a drain, and the second is the W ductile iron pipe, i.e., without spigot, ductile tube, or lined ductile iron tube.
Q:What is the K9 standard pressure for ductile iron pipes?
The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better. 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:The benefits of ductile iron castings
Nodular cast 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.
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:Comparison of ductile iron pipe and spiral steel pipe
Can only be used for drainage pipe for comparison, other uses are not mentioned in the same breath.
