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:How much is the manual installation fee of ductile iron pipes from 100 to 150 per metre?
According to the various connection modes after the installation of artificial fee at =8.7~9.0 yuan (about /M this is pure artificial installation fee, no other costs to calculate, if packet labor costs and construction should be appropriately increased when installed).
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 a ductile iron pipe dn400?
Ductile iron pipe nominal diameter is 80 ~ 2200 mm, compared with grey cast iron, high strength, good toughness, thin wall metal, less dosage, and can withstand high pressure, effective length of 5 meters, 6 meters and 8 meters; according to the different thickness of P, G two. It is the development direction of cast iron pipe.
Q:What are the meanings of cast iron pipe wall thicknesses LA, A and B respectively?
According to its manufacturing methods can be divided into: sand, centrifugal pipe, straight pipe, continuous cast iron pipe and sand pipe.According to the material used, it can be divided into gray iron pipe, nodular cast iron pipe and high silicon iron pipe.1 、 water supply cast iron pipe:The use of cast iron cast iron water pipe of No. 18 above by adding nodulizer, after centrifugal ductile cast iron pipe by centrifugal casting machine, the performance of ductile iron pipe with nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises water, gas, oil etc.. Water supply pipe is the first choice, with high cost performance.2 、 sand casting centrifugal cast iron pipe:The sand casting centrifugal cast iron pipe is made of gray cast iron. It is suitable for the transportation of pressure water such as water and gas.
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: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:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
Ductile iron castings have been used in almost all major industries. These departments require high strength, plasticity, toughness, wear resistance, and resistance to ductile iron
Q:What is the K9 standard pressure for ductile iron pipes?
Ductile iron pipe is a kind of cast iron. It is an alloy of iron, carbon and silicon. Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance.
Q:Fire water supply network adopts ductile iron pipe, the test pressure should be no more than MPa
Strictly speaking: the outer pipe network and the internal pipe network are the same. Minimum fire 1.0MPa, minimum sprinkler 1.4MPa. Because not only in accordance with the water pump, but also take into account the pressure on the fire engine.
