Q:Can ductile iron be welded? Is weldability comparable to gray iron?
Nodular cast iron welding can be determined, this should be in some high strength cast iron equipment used more, the tensile strength of normally ductile cast iron welding in welding is higher, is worse than the grey cast iron, it is actually very difficult to distinguish with the naked eye is ductile iron or cast iron the iron in the repair equipment, we usually use WE777 special cast iron electrode universal wide welding, but it is only for maintenance use, the effect is really good, reducing the risk of cracking and high strength welding rod matching to ensure the strength of welding.
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:What is ductile iron pipe?
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Execution standard GB/T13295-2003ISO2531/2003
Q:Why is the sound speed of nodular cast iron lowered after heat treatment?
This may be the material microstructure changes after heat treatment, is generally the pearlite content increased, the available change heat treatment and then check the corresponding microstructure and corresponding measuring sound velocity adjustment, such as annealing, normalizing etc..
Q:How can the cast iron pipe of the ductile iron pipe be repaired?
Get a pole. Or go around the corridor
Q:Can cast iron pipes not be used for domestic water supply and drainage?
Yes, the main use is, outdoor water supply pipe can be PE or ductile iron (socket connection). Indoor water is now used in general plastic pipes, but in the past seems to be able to use ductile iron, as for drainage, generally do pressure type drainage, when the choice is cast iron pipe. There are also indoor fire pipes using welded steel tubes or ductile iron.
Q:How much pressure can the ductile iron pipe socket meet?
After all, he is not steel, strength is low, toughness is poor. But a short period of about 100kg, things should be no problem.
Q:Advantages and disadvantages of ductile iron pipes?
The ductile iron pipe has a single length of 6 meters and a large wall thickness. The cast iron tube has a single branch length of 3 meters and a thinner wall thickness.
Q:Ductile iron pipe length is generally much
The water-cooled metal ductile iron pipe has a single length of 6 meters, and the current mainstream ductile tubes are water-cooled metal ductile iron pipes.
Q:QT400-10 nodular cast iron requires hardness of HRC47~51. Why can't quench hardness be reached?
QT400-10 shall ensure sufficient pearlite in the casting state, at least half of the pearlite. This is done with the temperature, time, and water. But if it is big, the heart hardness will not go up.
