Q:The role of chromium in nodular cast iron
Chromium has better strengthening and toughening effect in nodular cast iron. Chromium containing cast iron has the characteristics of high strength, high elongation, high impact value and low hardness.
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:Deep well spiral iron pipe, or ductile iron tube?
Ductile weakness: ductile cast iron pipes connected by human factors such as the operation level of responsibility, influence, construction not convenient. The advantages of PE PE PE pipe has good corrosion resistance and its anti inorganic performance than that of the metal pipe is much stronger in the buried without corrosion, construction convenient. Small diameter PE pipe in the price performance ratio is better than that of steel and ductile iron.PE tube have disadvantages: benzene, gasoline, carbon tetrachloride and other organic solvents have certain effect on pe. If the organic solvent is infiltrated into the polyethylene, the swelling will occur, and its physical properties will be decreased. Its pressure resistance and temperature resistance are poor.
Q:General cast iron prices now
Hubei, Suizhou, in 2010, normally 5000-7000 tons of iron, if required to join copper and other metals, the price is calculated. The price is very low, because the market price in Suizhou is the lowest in the whole country. Under normal circumstances, it should be 8000 tons a ton
Q:What does ductile iron pipe "K" mean?
K means wall thickness registration, general water supply and drainage, now China uses K9, and some countries in South America, such as Brazil, use K7.The wall is thick =k (DN/1000+0.5), such as K9's DN500 tube, with a wall thickness of =9* (500/1000+0.5) =9mm
Q:Does the cast iron pipe for spheroidal graphite need corrosion protection when laying underground?
In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the cast iron pipes, ductile iron pipes and finished product libraries can be better improved, with the nature of iron and the properties of steel
Q:How to choose a ductile cast iron pipe with guaranteed quality
Cutting testing: iron filing resistance, filing issued a "Shua" sound, little sticky file, debris was gray with a small amount of white spot, look at the particles of different size, with small particles of fine powder, finger milling, it is easy to make fingers black. Ductile iron filing: when the resistance ratio of gray iron is slightly larger, there are obvious "Shua" sound ", little sticky file, debris was gray with fine bright particles ranging in size but with large particles, with finger milling chips, can be dyed black to gray fingers, but more black the degree of light
Q:What is the difference between spheroidal graphite cast iron QT400-15 and QT400-15A? What does the A mean later?
The front is the material grade, and the back of the A should have special requirements.
Q:Why is the cast iron tube lined with cement? Under what circumstances are ductile iron pipes lined with cement, and under what circumstances do not have to be lined with cement?
The cement lining protects the water quality, reduces the head loss and improves the service life of the spheroidal graphite pipe. As long as the water delivery hose is used, the cement lining must be used. There is no lining cement for conveying air.
Q:Is the cast iron pipe buried in need of antiseptic treatment? What kind of anticorrosive materials are used?
Is to put the pipe surface rust corrosion, polished clean, brush again primer, and then wrapped a layer of glass cloth wrapped paint, two layers of glass cloth on the line, the thickness of not less than 6mm, painted with epoxy coal tar paint or asphalt paint
