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:How much is the installation cost of the ductile iron tube?
From the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve greater runoff; from the installation and maintenance cost, ductile pipe have more favorable price. The inner wall of zinc spray, anti-corrosion materials such as cement mortar.
Q:What is the minimum pipe diameter of cast iron pipe?
Nominal diameter of continuous grey cast iron pipe is 75~1200 mm, minimum 75 mm, maximum 1200 mm.
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
The cost is low, the construction cost is low, and the schedule is fast. Such as PVC, PE double wall corrugated pipes, etc..
Q:What new technologies are there for the installation of ductile iron pipes?
Type W: type W tube in the same pipe with high strength, low noise, good fireproof performance, long service life, with the characteristics of flexibility and good seismic performance, but also has synchronous construction, utilization rate is high, easy to pipe, reducing the hydraulic test of pipeline clearing times, shorten the construction period to improve economic benefits. In addition, this type of interface with bolts in the lateral fastening, avoids the defects of socket flexible interface flange is easy to damage, close to the wall to the fixed bolt, has the advantages of simple operation, so in the selection of building drainage pipes and fittings, with strong competitiveness. In addition, because the length of W pipe is 3M, the number of intermediate joints is greatly reduced, and any length can be intercepted in accordance with the requirements, thereby greatly saving the pipe material, reducing consumption and cost. W type socket with stainless steel hoop rib clamp, lined with rubber ring flexible connection, seismic performance and good sealing performance, no leakage and allowed to swing in a certain range. Therefore, W tubes are widely used both at home and abroad.
Q:What is the relationship between the mechanical properties of spheroidal graphite cast iron and its spheroidization rate?
Poor balling and poor performance. Can do under tensile. General level three or four or more on it
Q:Is the water cast iron pipe 100% for hydrostatic test?
After the site installation, according to the standard to test pressure, but a lot of construction units are not pressure test
Q:How can stainless steel pipes and ductile iron pipes be joined?
The stainless steel pipe can be used as a socket or socket, so as to be directly connected with the connection mode of the ductile iron pipe
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:Can ductile iron pipes be installed outdoors?
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. The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better.
