Q:Seamless steel tube with the tube with what is the difference?
Seamed tube can withstand the maximum pressure is generally less than 20 kg, which is the most secure use. It is generally used in water, gas, compressed air and other low-pressure fluid;
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
Formula: outside diameter - wall thickness * wall thickness *0.02466=, weight per meter! : 48-3*3*0.02466=3.3291
Q:How much is 4 inches steel tube MM?
Seamless root weight per meter: 1 mm (diameter - thickness) * wall thickness of *0.02466*1 meters is? Normal KG/M pipe length 8-11rice
Q:Are steel tubes and round steel in weight or length when purchased?
It's priced by weight. The cutting process should size to determine the length (otherwise - please specify the weight of the material), the material ration to calculate weight for cost accounting as.
Q:Hot galvanized steel pipe for use?
Hot galvanized pipe: in order to improve the corrosion resistance of steel pipe, galvanized steel pipe. Galvanized steel pipe hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, zinc plating cost is low, the surface is not very smooth.The hot-dip galvanized pipe is an alloy layer that causes molten metal to react with the iron matrix, thus combining the substrate with the two coating. Hot dip galvanizing is the first steel pickling, in order to remove iron, steel pipe surface after pickling, cleaning by ammonium chloride or zinc chloride solution or ammonium chloride and zinc chloride aqueous solution tank, and then into the hot dip tank. Hot galvanizing has the advantages of uniform coating, strong adhesion, long service life and so on. A complex physical and chemical reaction is formed between the steel tube matrix and the molten plating solution to form a corrosion resistant structure with a tight zinc - iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, it has strong corrosion resistance.
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's the difference between round and round tubes?
Round steel is a medium solid steel, of course the tube is hollow
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
This is according to the "water drawing standards" (GBT50106-2001) in 2.4.2-2 seamless steel pipe, welded steel pipe (straight or spiral seam), brass, stainless steel pipe, pipe diameter should be D diameter * thickness representation (such as D108 * 4 and D159 * 4.5); and the provisions of the habit of acting D with seamless pipe diameter.
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
The pipe material of heating pipe network should be designed according to the requirement. When the design is not specified, the following requirements shall be met:1 when the pipe diameter is less than or equal to 40mm, welded steel pipe shall be used.2 when the pipe diameter is 50 ~ 200mm, welded steel pipe or seamless steel pipe shall be used.3 when the pipe diameter is greater than 200mm, spiral welded steel pipe shall be used.
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless pipe featuresFirst, the product of the wall is thicker, it is more economical and practical, the wall thickness of the thinner, processing costs will be substantially increased it; secondly, the product process to determine its performance limitations, generally low precision seamless steel pipe: uneven thickness, tube inner surface brightness low and high cost of fixed length, and the inner surface pitting and black spots difficult to remove; the detection and plastic third, must be processed offline. Therefore, it has its advantages in high pressure, high strength, mechanical structure and timber.
