Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Other commonly used theoretical weight formulas per metre:Thread steel (Kg/m):W=0.00617 * D * D, D - sectional diameter (mm)Fang Gang (Kg/m):W=0.00785 * a * a, a - edge width (mm)Flat steel (kg/m):W= 0.00785 * b * D, B -- edge width (mm) d - thickness (mm)Round steel rod (kg/m),:W= 0.006165 * D * D, D - diameter (mm)
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Just name different, all refers to GB/T 3091-2015 "low pressure fluid transport welding pipe" contained in the galvanized pipe.Galvanized pipe means zinc plated, suitable for water, air, heating, steam and gas and other low pressure fluid conveying straight welded steel pipe, longitudinal submerged arc welding (SAWL) steel pipe and spiral seam submerged arc welding (SAWH) steel pipe.
Q:What is the diameter of the steel tube DN20?
Stress: the nominal diameter is not the outer diameter of the pipe, nor the inner diameter of the tube. It is not the average value of the inside and outside diameter (the nominal diameter of the equipment refers to the outer diameter).
Q:What time what time for gas pipeline steel pipe PE pipe
PE pipe is suitable for medium voltage and low voltage 0.4MPa below the pressure pipe wall thickness. According to the different pressure is not the same, so the steel tube can be used for high pressure.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The magnitude of the axial force acting on the steel member is only related to three factors, namely, the strength of the material, the sectional area of A and the longitudinal stability factor of F.
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: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:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
First, the surface of the steel pipe is treated by embroidery, which is more durable, not faster than the rapid oxidation, and will not form white rust on the steel tube;Two. The steel pipe is fully protected. After heating, each part of the steel pipe is plated with zinc, and the concave convex part is protected;
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
According to the metal processing performance, pipe size, quality requirements, as well as investment and benefits to choose different processing methods and corresponding auxiliary processes. The basic process of cold rolling of cold drawn pipe are: (1) tube feeding, the pipe material for hot-rolled finished or semi-finished tube, pipe extrusion pipe and welded pipe; (2) pipe material preparation, including inspection, bundling, pickling, cleaning, washing, drying, neutralization, grease and so on; (3) cold processing (cold or cold); (4) finished finishing finished including heat treatment, straightening, sampling, end cutting, inspection (manual inspection and various testing), pressure test, oiling, packaging and warehousing etc.. Different products are refined and the content varies.
Q:Where is the difference between seamless steel pipe and welded pipe
The steel tube is a hollow steel strip, used as pipe conveying fluid, such as oil, gas, water, gas, steam, in addition, the bending and torsional strength of the same, the weight is light, so it is widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
