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 is ductile iron pipe?
Ductile iron pipe is a kind of cast iron pipe. In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the material have been better improved, with the nature of iron and the properties of steel. Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Q:The difference between HDPE pipe and ductile iron pipe
Of different uses, ductile iron pipes are widely used for municipal water supply and drainage, rural drinking water and outdoor fire fighting works; mechanism cast iron pipes are mainly used in the city.
Q:What are the interface forms of ductile iron pipes? The best drawings are available. Thank you
T interface type sealing ring is a self sealing rubber ring, when the pipe internal pressure increases, the contact pressure between the seal and the pipe increases, T interface can not only allow the deflection angle of the axial displacement, and convenient for installation. When the T type interface is installed, the sealing of the rubber ring can be ensured as long as the socket is simply loaded into the socket and the rubber ring is pressed tightly. This kind of interface has the advantages of reliable sealing, good seismic resistance and corrosion resistance, and it is a better interface.
Q:Advantages and disadvantages of ductile iron pipes
Generally not used in high pressure pipe network (6MPa or more). Because the pipe is relatively bulky, the machine must be used when installing. When the water leak occurs after the test, all the pipes must be dug out, and the pipe can be hoisted to the height of the clamps. The clamps can be installed to prevent leakage.
Q:Method for cutting cast iron pipe
Depends on the material and the use of requirements. Ordinary gray iron, if the incision is not strict, such as water pipes. They are all sheared with hydraulic cutting machine, but the incision will not be very smooth. If it is ductile iron, and the incision requirements are high, it can only be used plasma cutting machine. General fittings, if not specifically required, shall not be cut by machining methods.
Q:Does the cast iron pipe need separate corrosion protection?
Ductile iron is characterized by its ease of decay and deformation, so if it is not a particular requirement, there is no need to do it alone
Q:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
Generally use tensile machine to do, I often operate, or you see the metallographic 3J above perlite 60% above should be no problem
Q:Ductile iron gears are generally treated without heat treatment
Certainly. At the very least, the casting must be annealed and other heat treatment according to the requirement of use
Q:Method for joining cast iron pipes
Cast iron pipe, cast cast pipe. 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
