Q:Luo what effect of ductile cast iron
Chromium is an anti graphitization element, which hinders the graphitization process of cast iron, increases the content of cementite (Fe3C) in the internal structure of cast iron, and stabilizes pearlite at the same time. It affects the mechanical and processing properties of nodular cast iron.
Q:Disadvantages of ductile iron pipes
Compared with cast iron, ductile iron has an absolute advantage in strength. The tensile strength of ductile iron is 60K, while the tensile strength of cast iron is only 31k. The yield strength of ductile iron is 40K, while the cast iron does not show yield strength, and eventually breaks. The strength to cost ratio of ductile iron is far superior to that of cast iron.
Q:How can 4 inch ductile iron pipe be connected with 2 inch galvanized pipe?
Ductile cast iron used for more than 18 by adding nodulizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
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:What new technologies are there for the installation of ductile iron pipes?
Because the new flexible interface mechanism of cast iron drainage pipe pipe in the development of China's relatively short history, compared with other drainage pipes, people know little of the present, with some experience of the author in the construction, the application of the performance, characteristics and engineering, to do some simple introduction.
Q:How does the white iron appear in the case of ductile iron?
Casting cooling, surface and thin section at often produce white. White tissue hard and brittle, poor processing performance, easy peeling. So it is necessary to use the annealing (or normalizing) method to eliminate white tissue. The annealing process: heating to 2 DEG C 550950 ~ 5 h, then 500 to 550 DEG C Furnace cooling again followed by air cooling. During high temperature insulation, high travel cementite eutectic cementite decomposition of graphite and A in the subsequent two carburizing cooling process and eutectoid cementite decomposition, graphitization process. Due to the decomposition of cementite, resulting in the decrease in hardness, thereby improving machinability.Hope to help you.
Q:Usage of ductile iron pipe expander
Usage of ductile iron pipe expander:1, the expansion device should check its type, specification and piping configuration before installation, must comply with the design requirements.2, the expansion of the inner sleeve should be noted that the direction of the inner sleeve is consistent with the direction of the medium flow. The hinge rotation plane of the hinge type telescopic device should be consistent with the displacement rotation plane.3, the need for "cold tight" expansion device, pre deformation of the auxiliary components should be installed in the pipeline before they can be removed.4, it is strictly prohibited to use telescopic deformation method to adjust the installation of the pipe, so as not to affect the normal function of the telescopic device, reduce the service life and increase the piping, equipment and supporting components of the load.5 、 during installation, welding slag is not allowed to splash to the surface of wave shell, and the wave shell is not allowed to suffer other mechanical damage.6, pipe installation is completed, should be removed as soon as the wave expansion device used for installation and transportation of yellow auxiliary positioning components and fasteners, and according to the design requirements will be transferred to the specified position limiting device, the pipe system has the ability to compensate fully in the environmental conditions.
Q:Ductile iron pipe, socket connection, pipe length, you can cut open it?
Yes, but the pipe that needs cutting is a cut off pipe with a scissors mark.
Q:Ways of connecting ductile iron pipes
Ductile iron pipes are all made of flexible interfaces.
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.
