Q:What is the difference between flexible joint mechanism and seismic cast iron pipe DN100 and ductile iron pipe?
Nodular cast iron has high strength and strong plasticity. The tensile strength of ductile iron is twice that of gray iron, and the yield strength even exceeds that of cast steel.
Q:Why does the cast iron pipe always run off when testing?
If the pipe is exposed for pressure test, you must add a pier, or else the fittings fly out. You are not surprised. At the same time, the pressure test before the ink tube to make full immersion bubble discharge clean, or a big easy gas pressure pipe explosion.
Q:What are the differences between cast iron pipes W and A?
W cast iron pipe is subdivided into W cast iron pipe and W1 cast iron pipe, the difference between them is the difference between the wall thickness. Because of the cold weather, the requirements for pipes are higher. The W cast iron pipes are mainly used in the north, while the W1 cast iron pipes are mainly used in the south.
Q:What material is the cutting tool for ductile iron?
The tool manufacturers so much, such as: Santak, Kenna, widia, Dai Jie, Walter, MITSUBISHI, Toshiba, ISCA, TaeguTec, Zhuzhou, each of the grades are not the same. But according to your specific processing workpiece and processing time and precision requirements, can choose the most suitable tool.
Q:The plug connection DN800 ductile iron pipe has been installed. "Shall I think so?"
Ductile iron pipes are defined as pipes made by casting more than 18 of casting molten iron by adding a spheroidal agent and then centrifugally centrifugally cast by a centrifugal nodular cast iron machineDuctile iron pipe ([span]Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..
Q:How to correctly measure ductile iron pipe
This need to find the right tools, Michi, caliper, amount to ductile pipe and pipe fittings and pipe fittings of the outer diameter, inner diameter, length and wall thickness were measured, eleven.
Q:How many degrees can the ductile iron pipe be each?
Minimum tensile strength: 420/Mpa, minimum yield strength: 300/Mpa, minimum elongation 7%.
Q:Ductile iron pipe is how many years warranty
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:What is the difference between cast iron pipe and seamless steel pipe and galvanized steel 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.
Q:How to choose a ductile cast iron pipe with guaranteed quality
1, first of all choose the regular manufacturers of ductile iron pipe products.2, the choice of ductile iron pipe, should be based on the specific circumstances of the construction site, select the pipe and fittings corresponding to the form of interface.3, rubber rings recommend the use of three yuan ethylene propylene rubber ring and so on.4, listen to the voice, knocking the iron: short duration. The iron ball: crisp sound, echo, short duration5, the cutting surface is gray: gray, shiny surface seems very dark, very rough. Ductile iron: gray, gray luster is bright, like gray surface roughness.
