Q:What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?
DN represents the path of the tube". Fair represents diameter. Path is the diameter of the fluid through which it should be inside. The diameter may be the outer diameter or the inner diameter. The diameter is only used when the pipe is used for flow through. Fair as long as the garden can be used. According to the requirements of mechanical drawing fair, DN text notes.
Q:Seamless steel pipe is how to do it?
1. seamless steel tubes for structural purposes (GB/T8162-1999) are seamless steel tubes for general structural and mechanical construction.2. seamless steel pipe for fluid transportation (GB/T8163-1999) is used to transport water, oil, gas and other fluids of general seamless steel pipe.3. seamless steel tubes for low and medium pressure boiler (GB3087-1999) is used in the manufacture of various structures of low and medium pressure boiler superheated steam pipe, superheated steam pipe, boiling water pipe and boiler flue tube, pipe and brick arch tubes of high quality carbon steel hot rolling and cold drawing (rolling) seamless steel tube.4. high pressure boiler seamless steel tube (GB5310-1995) is used for the manufacture of high-pressure and above the pressure of water boiler heating surface for high-quality carbon steel, alloy steel and stainless steel heat-resistant seamless steel pipe.5. high pressure seamless steel tube (GB6479-2000) for chemical fertilizer equipment is a kind of high quality carbon structural steel and alloy steel seamless pipe for chemical equipment and pipes of working temperature of -40~400 DEG C and working pressure of 10~30Ma.6. seamless steel tubes for petroleum cracking (GB9948-88) are tubes, heat exchangers and seamless steel tubes used in refineries.
Q:Will the steel tube dance?
Pole dancer performing double pole dance performance is much higher than single pole dancing difficult, because not only refers to the double pole dance together the two pole dance, two people should pay attention to the dance and tube movement, if two people do not fit to dance moves and skills on the tube action, you jump you. I jump, that wasn't a real double pole dance, dance like a double tube. If the two dance movements and pipe movements are not good enough or not natural enough, they will destroy the effect of the whole dance and make the audience feel that the dance is chaotic and not beautiful, so it is better to see a single pole dance. But the dancer's double pole dance performance is good, more powerful than single pole dance, and more aesthetic and artistic.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The same length, the same pipe diameter, the same material strength is hollow, the ratio of area of steel (solid), and the cyclical and slender radius smaller than the larger, so the longitudinal stability coefficient is smaller, three factors, two factors are weak in steel reinforced, another factor: strength, they are the same, no doubt, steel reinforced bearing less than.
Q:How to make the internal tooth of the steel pipe?
At present, in our country, 300MW or 600MW or more large capacity sub critical and supercritical thermal power boilers are designed or imported abroad. Membrane internal wall tubes are widely used in membrane water wall.
Q:What's the use of steel pipe?
No other type of steel can replace the steel tube entirely, but the steel tube can take the place of some sections and bars. Steel pipe is very important to the development of national economy and the improvement of human life quality, much better than other steel products. From the people's daily utensils, furniture, water supply and drainage, gas supply, ventilation and heating facilities to all kinds of agricultural machinery equipment manufacturing, underground resources development, national defense and space use guns, bullets, missiles, rockets and so cannot do without steel.
Q:What is the outer diameter of the steel tube?
The diameter of a steel pipe refers to the diameter of the steel pipe. The specifications of the steel tube is normal with diameter (diameter and thickness) said, for example 100MM outer diameter and wall thickness of 5MM tube is marked with 100*5.
Q:What is a tight steel tube?
The tight steel tube is called "galvanized steel pipe with sleeve connection" or "flat pipe of steel metal for electrical installation". JDG. The utility model relates to a novel protective conduit for an electric circuit. The connecting sleeve and the metal accessory are provided with a wire pipeline composed of screw fastening connection technology, and the utility model does not need to do cross grounding, welding and covering, and the appearance is silvery white or yellow.
Q:45 and 316 which steel tubes are of high hardness?
No. 45 steel for high-quality carbon structural steel, the hardness is not high machining, used to make the template, mould studs, guide column, subject to heat treatment. 45 steel quenched and tempered hardness between HRC20~HRC30; 45 steel quenching hardness between HRC55~58, the limit value of up to HRC62.
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
DN150 4mm wall thickness welded steel pipe theoretical weight is 16.21kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 4mm, C=1.032, DN150, theoretical weight and wall thickness of 4mm galvanized steel is 1.02*16.21=16.7287kg/m = 16.73kg/m.
