Q:Ductile iron and gray iron is what are the advantages and disadvantages of it
Comparison of ductile iron and cast iron (gray iron)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. Ductile iron is the same as cast iron in corrosion resistance.
Q:What is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
The use of cast iron by adding more than 18 nodularizer, 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:How can the old water pipe ductile iron pipe be opened with three flanges?
There are finished products with flanges, but they are not easy to buy. They are basically useless. Now basically the adoption of the pipe, so it is recommended to use the tray flange, disk plug: one for the flange, one for the socket; socket: one for the mouth, one for the socket. According to the diameter of pipe fittings, there are usually equal diameter three pass, different diameter three pass and so on. According to the direction of branch pipe, there are three straight and oblique three. In accordance with the connection mode, there are three ordinary, threaded three pass, card sleeve three, and socket three. The connecting flange of the sleeve is connected with the connecting angle of the bearing mouth, and the telescopic device can also be used. The connection between the pipe and the pipe adopts the form of socket type or flange disk interface. According to the function, it can be divided into two kinds: flexible interface and rigid interface. The flexible interface is sealed with rubber ring, which allows a certain degree of corner and displacement, so it has good seismic resistance and tightness, and it is easy and quick to install than rigid interface.
Q:What are the risks in the process of conveying ductile iron pipes?
Transportation: when transporting pipes by car, two or more pieces of wood should be placed on the platform. The tubes are placed on the wood and fixed with wedges. The pipe out of the car parts shall not exceed the length of 1/4 in vitro. When more than one layer of pipe is installed, the direction of the pipe shall be reversed in each layer, and cushion or cushion shall be added between the two layers of pipes. Finally, the wire rope and cushion are fixed firmly. In the process of transportation, check the risk of falling pipe frequently, check whether the stop wedge is loose, slow down when the road is rough or sharp turn.
Q:Is the spigot and socket connection of the ductile iron tube reversed?
The whole process is formed by the radial compression of the pipe blank and the stretching process of the branch pipe. Different from the hydraulic bulging three, the metal of the three way joint pipe is compensated by the radial movement of the tube blank, so it is also called radial compensation process.
Q:The benefits of ductile iron castings
Nodular cast iron, is a kind of high strength cast iron material developed in 50s twentieth Century, its comprehensive performance is close to the steel, it is based on its excellent performance, has been successfully used in casting complex stress, strength, toughness and wear resistance requirements of the higher parts.
Q:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
600-3 is pearlite + a small amount of ferrite matrix ductile iron. Pearlite edge region. 10%, center. 70600-3. Two sets of numbers indicating the grades and mechanical properties of nodular cast iron. The former represents the minimum tensile strength
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?
Cement lining to protect water quality, reduce loss, improve the service life of the pipeline ductile, ductile iron pipes are generally lined, which the en545 standard specifies the quality of what kind of what kind of cement.
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.
Q:What is the difference between a PE fire hose and a ductile iron pipe?
Cast iron pipe: cast pipe made of cast iron. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small. According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds. Divided into gray cast iron pipe and nodular cast iron pipe according to different material. According to the interface form, it is divided into flexible interface, flange interface, self anchored interface, rigid interface and so on. Among them, the flexible iron pipes rubber sealing ring; flange interface cast iron pipe flange fixed in the rubber pad, the flange gasket sealing; rigid interface cast iron pipe socket is large, straight pipe is inserted, sealed with cement, this technology has been basically eliminated.
