Q:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
The material can be annealed and the process is simple, that is, heating the workpiece and cooling it naturally. In this way, the hardness of the workpiece can be reduced.
Q:Ductile iron and gray iron is what are the advantages and disadvantages of it
Comparison of nodular cast iron and cast steelThe strength of nodular cast iron is comparable to that of cast steel. Ductile iron has higher yield strength, the lowest yield strength is 40K, while the yield strength of cast steel is only 36k. In most municipal applications, such as water, brine, steam, ductile iron has more corrosion resistance and oxidation resistance than cast steel. Because of the spheroidal graphite microstructure of nodular cast iron, nodular cast iron is superior to cast steel in reducing vibration ability, so it is more beneficial to reduce stress. An important reason for choosing ductile iron is that ductile iron costs less than cast steel. The low cost of ductile iron makes this material more popular, more efficient and less costly for ductile iron.
Q:An urban infrastructure construction, water supply pipe is ductile iron pipe and PE pipe, thank you
Water supply pipe is the first choice, with high cost performance. Compared with the PE pipe, from the installation time, ductile pipe PE pipe installation is simple and rapid, and after the installation of internal and external bearing pressure better;
Q:How to distinguish flexible and rigid interfaces between cast iron pipe joints
Rigidity is a way of connection that has been eliminated. Sealing is achieved by pouring cement into the spigot
Q:Maximum pipe diameter of ductile iron pipe
The maximum diameter of ball milling cast iron pipe can be DN3000.. For long pressure pipeline, the performance of ball milling cast iron pipe is better than that of PCCP tube, and the performance is reliable, safe and stable!
Q:Ductile iron pipe connection mode
Jack painted on the outer surface and rubber lubricant: lubricant evenly installed ring inner surface, outer surface coating in the socket to socket socket parts lubricant line all the brush in the socket.
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
Then answer your question: first, the strength of ductile iron is much higher than that of ordinary low carbon steel, such as Q235. Corrosion resistance is much higher than that of ordinary steel pipe and the cost is lower than that of ordinary steel pipe. Second, large diameter steel pipe can only be made of spiral welded pipe, seamless steel pipe is particularly expensive, will not be used. The welded pipe is welded, easy to corrosion water leakage. Third, galvanizing is also a life and very expensive, the pipe has a fluid will wear on the inner wall, zinc plating is meaningless. Galvanized pipe is generally used as a water supply pipe, large caliber water pipes, such as more than 250, and now do not use steel pipes, mostly plastic pipes
Q:The difference between spheroidal graphite cast iron pipe and HDPE water supply pipe
Because the HDPE pipe flexibility is good, in the face of obstacles or trench excavation in straight pipe laying conditions can not directly, but the ductile iron pipe can not, it is sometimes necessary to use the words such as elbow or tube fittings to connect the transition. In this way, the HDPE pipe is superior to the ductile iron pipe in the pipe fittings.
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:Method for cutting large diameter ductile iron pipe
When the oxygen and acetylene volume ratio is greater than 1.2, is formed. As more oxygen, burning, the flame length is shortened obviously, cone tapered inner flame almost disappeared, and a strong desire. Making due to oxygen, the oxidation of metal, so are not widely used, only used for welding of brass, to prevent evaporation of zinc.
