Q:SC15 what does galvanized steel pipe look like?
Zinc plating: galvanized steel pipe hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, with uniform coating, adhesion, long service life and so on. The cost of galvanizing is low, the surface is not very smooth, and the corrosion resistance of itself is much better than that of galvanized pipe. Refer to
Q:Heating system DN40 and DN32 welded steel pipe how to connect?
As for the flange connection: low pressure pipeline is generally not used in this way, can be divided into threaded flanges and flange welding flange, and the flange connecting pipes of different diameters, only the welded flange to diameter, said in a low pressure pipeline which has low pressure pipe connection make an unnecessary move, this is not much, but there are also people with non the standard flange for connecting different pipe diameter, which is not consistent with the technical specification!
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.
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 many meters per ton of steel tube?
General scaffolding tube diameter 40mm, specifications specify wall thickness of 3.5mm, the actual wall thickness of 3.2 - 3.4mm.The theoretical weight per meter is 3.85kg and the wall thickness is 3mm.Hence a ton of steel is about 260m.
Q:Galvanized steel pipe DN100 and SC100
Zinc plating, hot dip galvanizing and cold galvanizing, to see the design instructions and design requirements, which will explain
Q:What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?
DN is a kind of Engineering path, not the actual value, due to the different standards, so the actual corresponding values is not the same; phi is refers to the actual value, the same national standard pipe inside the steel pipe, the actual value is the same, for example, GB/T8163 and GB GB fluid pipe spiral pipe and GBT/T9711.1 GB/T12459 the same nominal diameter corresponding to the actual value is the same as the actual value; and American Standard steel standard ANSI B 16.38 and ANSI B 16.9 standard American Standard fitting the same nominal correspondence is the same. If marked, the nominal diameter should be added DN, and the actual value can be omitted.
Q:What is the size of seamless steel tube DN150?
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 withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, 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 ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:What is the difference between steel pipe and round steel?
Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:Fastener type steel pipe scaffold external parts name
Foot board can be made of steel, wood, bamboo and other materials, each quality should not be greater than 30kg. Stamping steel foot board is a kind of commonly used foot board, usually with thick 2mm steel plate pressing, length 2-4m, width 250mm, the surface should be anti-skid measures. Wooden feet can use the thickness of not less than 50mm fir wood or pine production, length 3~4m, width of 200-250mm, both ends should be galvanized steel band two, in order to prevent the wooden foot end of the destruction.
