Q:What are the differences between cast iron pipes W and A?
Cast iron drainage pipe generally divided into three categories, namely W type socket cast iron pipes, cast iron pipes of A type, B type cast iron drainage pipe, the three pipes have good seismic performance, strong sealing performance, simple construction, convenient maintenance, reliable use, so it is also called the cast iron pipe for earthquake.
Q:The role of chromium in nodular cast iron
In order to further understand the mechanism of chromium in ductile iron, the application of electronic scanning and other test means, from chrome crystal structure, crystallization, solidification, heat treatment transformation principle, further study on the mechanism of chromium in ductile iron.
Q:DN300 what's the price of the ductile iron pipe / the weight and the price of one meter?
The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better.
Q:How much is the installation cost of the ductile iron tube?
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 through various anti-corrosion methods;
Q:What are the specifications for the installation of water ball iron pipes?
Ductile cast iron pipe is characterized by mild, high, thin wall, pressure resistance, impact resistance, corrosion resistance, seismic resistance and other properties. The flexible interface is used for the pipeline interface, and there is a certain elongation and deflection angle. The utility model has the advantages of the raw iron pipe and the steel pipe material, and avoids the defects of iron and steel.
Q:Do ductile iron pipes have inner enamel?
If the market supply is indeed difficult, can be done by the owners, Design Institute of supplier relationship; if the design institute requires it to provide products can persist in wilfully and arbitrarily, the available information (if the market can not supply, design a hair ah).
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 does the white iron appear in the case of ductile iron?
Casting cooling, surface and thin section at often produce white. White tissue hard and brittle, poor processing performance, easy peeling. So it is necessary to use the annealing (or normalizing) method to eliminate white tissue. The annealing process: heating to 2 DEG C 550950 ~ 5 h, then 500 to 550 DEG C Furnace cooling again followed by air cooling. During high temperature insulation, high travel cementite eutectic cementite decomposition of graphite and A in the subsequent two carburizing cooling process and eutectoid cementite decomposition, graphitization process. Due to the decomposition of cementite, resulting in the decrease in hardness, thereby improving machinability.Hope to help you.
Q:An urban infrastructure construction, water supply pipe is ductile iron pipe and PE pipe, thank you
Because the construction of municipal water supply pressure will be relatively large, generally used in the selection of pipe centrifugal ductile iron pipe, he has properties of iron essence and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, ductile iron pipe is mainly used for municipal, industrial and mining enterprises, water supply, gas, oil etc.
Q:What are the requirements for the hydrostatic test of ductile iron pipes?
The hydraulic pressure test shall be carried out in the backfill before trying to allow the pressure after passing the backfill, backfill, the graded gravel fill to 300mm above the top of pipe, and then the soil backfill, backfill process by 200~300 tamped pipeline above 500mm within more than 500 can be used in artificial ramming, mechanical compaction. The degree of compaction shall not be less than 0.93.
