Q:How many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?
This is such a small piece, do not worry about shrinkage, mainly pay attention to sand hole and slag. With Disa wet molding line, a box of more pieces, suitable for mass production, defects will be relatively less. By using other methods (resin sand coated sand, etc.) can also be the main attention, don't type it, then the level of liquidity and relatively ductile iron, gray iron poor, sand and gas can not go up, sand holes or pores will spread in the discus plane.
Q:Which is better, ductile iron pipe and spray plastic pipe?
Ductile iron pipe corrosion resistance, strength, it is said that the Ming Dynasty ordinary cast iron works now, and now has a new type of dedicated, can be used, construction becomes very convenient, ductile iron pipe has no effect on water quality. Plastic sprayed steel pipe is a new type of pipeline with higher price.
Q:What is the K9 standard pressure for ductile iron pipes?
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:How can the cast iron pipe be connected?
Depends on what type of, A type with flange connection, W type stainless steel band clamp connection
Q:Does the cast iron have size 250? What's the performance?
Ductile iron does not have size 250. Ductile iron is the beginning of QT, QT400-15, QT450-10, QT500-7 is the general use of nodular cast iron brand. 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 seam.
Q:How to choose a ductile cast iron pipe with guaranteed quality
1, first of all choose the regular manufacturers of ductile iron pipe products.2, the choice of ductile iron pipe, should be based on the specific circumstances of the construction site, select the pipe and fittings corresponding to the form of interface.3, rubber rings recommend the use of three yuan ethylene propylene rubber ring and so on.4, listen to the voice, knocking the iron: short duration. The iron ball: crisp sound, echo, short duration5, the cutting surface is gray: gray, shiny surface seems very dark, very rough. Ductile iron: gray, gray luster is bright, like gray surface roughness.
Q:What is the difference between spheroidal graphite cast iron QT400-15 and QT400-15A? What does the A mean later?
This should be said in front of the material, and later add A, should refer to the grade
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:When the ductile iron pipe is pressed, the three links are always running out. What should be done?
This situation depends on whether the pipeline installation is in place and the apron installation is standard. If there are no other problems, it is recommended to play a cement pier, half a pack of three can be solved.
Q:Will the quality of ductile iron shrink?
Fool you. It is normal that the surface shrinks and goes down, but it can not be said to be good.
