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:Why does the cast iron pipe always run off when testing?
The pipeline is installed, straight section of each pipe will be added pier, concrete pipe, elbow, three links should also have concrete pier, specific installation method according to GB Atlas 03SS515, and the straight pipe to soil, pipeline interface will be exposed, easy to check.
Q:What material is ductile cast iron 235A?
Ductile iron is a pig iron
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 acceptance of cast iron pipe material?
A cast pipe made of cast iron. 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.
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 effect does magnesium play in nodular cast iron?
Magnesium can be graphite precipitated in spherical form.But the specific mechanism is not clear, and now it is still debated in the academic circles.In addition, magnesium and sulfur generate MgS, which removes S from molten iron, which impedes the formation of spheroidal graphite.Therefore, Mg has two functions to eliminate the influence of S on Nodular Iron and promote the precipitation of graphite in spherical form.
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:How many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?
Is it better to use precoated sand, but only a little higher cost?.
Q:The difference between flexible joint cast iron pipe and flexible anti-seismic cast iron pipe
Nodular cast iron pipes and fittings technical manual PDF download Fan Yingjun handsome date: Author: fan manufacturing technology, in January 2006, this book introduces the ductile iron pipe interface form, quality standard, installation technology and special use of ductile cast iron pipe and other content, lists all the technical parameters for ductile iron pipes, pipe fittings interface in order to facilitate the readers to use and accessories
Q:Will the quality of ductile iron shrink?
I am a professional casting, I can certainly tell you what he said, there is no basis, you see, the concave is due to do not have a good time, where the hot metal supplement
