Q:The role of chromium in nodular cast iron
In order to further understand the mechanism of chromium in ductile iron, the application of electronic scanning and other test means, from chrome crystal structure, crystallization, solidification, heat treatment transformation principle, further study on the mechanism of chromium in ductile iron.
Q:Luo what effect of ductile cast iron
Chromium can improve the hardness, strength and wear resistance of nodular iron, and increase bainite in bainite ductile iron.
Q:What are the risks in the process of conveying ductile iron pipes?
Pile up: when the pipe is stacked, the lower part of the pipe should be covered with a tie or cushion block. The socket of the pipe is interlocked with each other, and the stop wedge must be put in place to prevent the pipe from rolling. Not allowed to be piled on marshes, rough slopes, or badly polluted areas.
Q:How can the connection of ductile iron pipe elbow be convenient for connecting?
The utility model relates to a groove connecting pipe which has the function of sealing and sealing, and mainly comprises three parts: a sealing rubber ring, a clamping band and a locking bolt. The inner rubber sealing ring is arranged on the outer side of the connecting pipe and is matched with the pre rolling groove, and then the outer ring is buckled on the rubber ring, and then can be fastened with two bolts. Because of the special sealing structure design of the rubber sealing ring and the clamp hoop, the groove connecting piece has good sealing property, and the sealing property is enhanced correspondingly with the increase of the fluid pressure in the pipe.
Q:DN300 what's the price of the ductile iron pipe / the weight and the price of one meter?
The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better.
Q:How much is the installation cost of the ductile iron tube?
Ductile iron pipes mainly called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
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:Does centrifugal cast iron pipe work well with lining cement? Will it scale and breed bacteria?
Poor hydraulic performance and high energy consumption. The roughness coefficient of the prestressed reinforced concrete pipe is between 0.013 - 0.014, so that the pipeline resistance of the pipeline with the same pipe diameter is higher than that of the same water content. Because of its high roughness, after a period of use, the pipeline will be blocked by bacteria, shellfish breeding and reproduction. As the service life increases, the inner diameter of the pipe will gradually shrink and the resistance will increase.
Q:How can the ductile iron pipe be welded?
If the hole on the ductile iron pipe, you can use special hoop lined flexible rubber ring, rubber ring and pipe wall coating with rubber ring, glue to be fixed.
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!
