Q:Is the crankshaft material forged or ductile iron?
Cast iron can not be forged, only steel, malleable iron can not be forged, only the crankshaft is particularly hot, can not meet the strength of the hardening when forging
Q:How much is the working pressure of ductile iron pipe used in water supply pipe and how is MPa determined?
No, the work pressure is generally 0.4~1.6MPa, but the ultimate test pressure of ductile iron pipes is about 4.0MPa.
Q:Why is the sound speed of nodular cast iron lowered after heat treatment?
After the heat treatment, the microstructure of the material changes, the graphite changes, eliminating the internal stress of molecules, thus slowing down the speed.
Q:What is cast iron pipe?
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 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:Ductile iron gears are generally treated without heat treatment
Heat treatment must be necessary, generally annealed first to machine, after quenching or nitriding treatment
Q:The plug connection DN800 ductile iron pipe has been installed. "Shall I think so?"
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 DN400 installation charge for ductile iron pipes?
The wages paid under special circumstances: refers to the provisions of the state laws, regulations and policies, due to illness, injury, maternity leave, family planning leave, funeral leave, leave, leave, leave, regular shutdown, implementation of national or social obligations due to pay a certain percentage of wage hourly wage or salary when.
Q:Ductile iron pipe is flexible pipe or rigid pipe
Steel tubes, of course, because ductile iron pipes are not easily deformed.
Q:What's the difference between cast iron pipe and steel pipe?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
