Q:Luo what effect of ductile cast iron
It should be chromium, chromium is anti graphitization elements in ductile iron if the content for a long time, will hinder the graphitization of cast iron, the iron cementite microstructure (Fe3C) content increased, the chilling tendency of the cast iron increases, will make iron brittle, hard, affect the mechanical properties and processing properties of nodular cast iron.
Q:Which is good for water polo cast iron pipe steel pipe?
In summary, if the demand is not high, the use of stable environment, pressure and vibration is not a place recommend the use of ductile iron pipe; if is an important facility for high requirements or site conditions, abnormal conditions, vibration and impact may be relatively large, with ordinary seamless steel tube.
Q:Is nodular cast iron pipe filled with Yau Ma Tei?
Ductile iron pipes are defined as pipes made by casting more than 18 of casting molten iron by adding a spheroidal agent and then centrifugally centrifugally cast by a centrifugal nodular cast iron machineDuctile iron pipe ([span]Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..
Q:What is the disadvantage of nodular cast iron in excess of silicon?
Therefore, the increase of silicon content in nodular iron greatly improves the strength index and reduces toughness. Ductile iron has a greater crystalline undercooling and a tendency to chill when treated by spheroidizing, and silicon reduces this tendency.
Q:Qianwei County ductile iron pipe which tool to use cutting convenience?
Cutting the ductile iron pipe by grinding is grinding and cutting the ductile iron tube continuously by grinding wheel until it breaks. To cut ductile iron pipes by grinding cutting method, the cutting parts should be crossed at first so as to avoid deviation during cutting. Place the drawn ductile iron tube in the cutting machine and fix the ductile iron tube and clamp it with a built-in clamp. Next, start the cutting machine and gradually press the handle of the cutting machine. The grinding wheel cuts into the ductile iron tube until the ductile iron pipe is cut off. When exerting pressure on the handle, do not force too hard at once, otherwise it will cause the grinding wheel to break. In the operation of the machine, the operator must not stand on the side of the grinding wheel, so as to avoid accidents. When the wheel appears in cutting, vibration, shaking, uneven phenomenon, should immediately stop the operation, check whether there is the wheel gap, if damaged, must be promptly replaced, to ensure safety and normal. Good cutting ductile cast iron pipe section, if there is to prevent the use of burrs, can be removed by grinding or machining file.
Q:Usage of ductile iron pipe expander
Ductile iron expansion is mainly provided with large flexible, easy installation, the product main material for nodular cast iron, nodular cast iron is mainly through spheroidization and inoculation by spherical graphite, effectively improve the mechanical properties of cast iron, especially the plasticity and toughness increased, resulting in higher than the strength of carbon steel. The material mainly has high strength of plasticity and toughness, and its development at home and abroad is very fast, the output has exceeded cast steel and malleable cast iron, become second only to gray cast iron casting alloy material. Spheroidal graphite is obtained by spheroidizing and inoculation of nodular cast iron. It can effectively improve the mechanical properties of cast iron, especially improve the plasticity and toughness, so as to obtain higher strength than carbon steel.
Q:What is a slide in type T flexible interface?
As long as the socket is inserted into the slot, the installation is quick, labor-saving and airtight, and what is good is also good
Q:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
Choose carbide or whole carbide drill, about 90HRC in hardness. But it requires a high number of drills, around 3000.
Q:What is the exterior anticorrosion of nodular cast iron pipes?
Spraying anti-corrosion paint, usually first spray a anticorrosive paint, and then primer 2, paint 2!
Q:Can the underground cast iron pipes be connected with clamps to form buttress?
Best not to, because the use of clamp connection way to connect the poor integrity of the pipeline, the base treatment is not in place or uneven settlement, it is easy to produce deformation, resulting in pipe bending deformation, easily leaked from the junction.
