Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Outside diameter 60mm, thickness 3.5mm seamless steel tube per metre weight: 4.88 kg. When calculating the theoretical weight (Kg/m) per metre of steel tube, the theoretical weight meter of the steel tube can be checked directly, and the formula formula can also be used.
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:What's the difference between seamless steel pipe and welded pipe?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared with the solid steel such as round steel, the steel tube is lighter in strength and is an economical section steel when the flexural strength and torsion strength are the same.Widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing circular parts, can improve the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
12Cr1MoVG is a kind of material for alloy tubes. The main purpose is to make the steel structure in the boiler, the use temperature of 580 degrees, requiring high temperature resistance steel plate, durable strength, steel plate in the normalized and tempered state delivery. 12Cr1MoV alloy tube is based on high quality carbon structural steel. It is appropriate to add one or more alloy elements to improve the mechanical properties, toughness and hardenability of steel.
Q:What quota is reserved for buried DN20 steel pipe?
If it is reserved for embedded pipe pre buried steel waterproof casing, set of waterproof casing steel production and installation is to set the quota items, if the outdoor installation of welded steel pipe buried steel casing pre quota items, if it is a reserved hole, then there is no need to set the quota items.
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:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Welded and seamless steel pipe is divided according to the processing form, usually welded seam steel tube, seamless steel tube drawing and hot two ways, carbon steel is material, galvanized pipe is welded pipe production after the surface is galvanized
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
The difference between ERW (longitudinal resistance welding) and HFW (high frequency welding) is mainly due to the different principle.
Q:Are galvanized steel tubes the same as degaussing steel tubes?
Also known as galvanized steel pipe, hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, with uniform coating, adhesion, and long service life. The cost of galvanizing is low, the surface is not very smooth, and the corrosion resistance of itself is much worse than that of galvanized pipe.
Q:Can seamless steel pipe and ordinary steel pipe be welded?
Steel pipe and seamless linking points, you said should refers to ordinary steel pipe joints, if only consider the butt welding problem, two kinds of steel can be welded. But the mechanical properties of the seamless steel pipe and tube with different, generally the main difference is the two kinds of steel can withstand the pressure of the former than the latter to be good.So if your project is seamed steel pipe can be, then the two pipe welding, welding and butt welding interface is completely no problem.
