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:Fastener type steel pipe scaffold steel pipe wall thickness
According to the "construction of fastener type steel pipe scaffold safety technical specifications JGJ130-2011" stipulates that the specification of steel pipe should be Phi 48.3 * 3.6, that is, wall thickness is 3.6mm. The standards in Shanghai are in line with national standards and 3.25mm can be used.Shelf tubes commonly used specifications, sizes are generally 48.3x3.0, 48.3x3.25, 48.3x3.5.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Fastener type steel pipe scaffold, fastener is the connection between steel pipe and steel pipe, and its form has three kinds, namely right angle fastener, rotating fastener, butt fastener
Q:What's the actual size of the DN25?
Steel pipe production technology development began in the bicycle manufacturing industry rise, early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry, petroleum and natural gas drilling and mining and transportation, are promoted in production the quality and variety, the development of steel tube industry.
Q:Material of welded steel pipe
GB/T3091-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is Q235 grade a steel.
Q:What connections are there for concrete filled steel tubular column foundations?
The Liang Duan local widening joint is achieved by the continuous construction of longitudinal steel bars around the steel tube. At the beginning of the creation of additional stirrups should be widened longitudinal reinforced wrap, Liang Duan local widened joints of steel reinforced concrete beam and corbel overlapping transition zone can transmits beam internal force, bending steel bracket in both shear and participation. The node form is used in building engineering in Xiamen. The force transfer path of this joint is clear and reliable, with less welding on site and more convenient for construction. This kind of node passes shear stress through the bracket, and the stress is more concentrated.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
Full house scaffold is mainly used in the decoration construction of the single storey workshop, exhibition hall, gymnasium and so on. It consists of vertical pole, cross bar, diagonal brace and scissors support
Q:What's the difference between seamless steel pipe and welded pipe?
The difference can be seen from the outward appearance that the welded pipe is welded by roll up.
Q:Does the seamless steel pipe need rust removal?
The main use of steel wire brush and other tools to polish the surface of the steel, you can remove loose or tilted skin, rust, welding slag and so on. Manual tool derusting can reach Sa2 level, power tools derusting can reach Sa3 level, if the surface of the steel attached to the solid oxide sheet, tool rust removal effect is not ideal, can not reach the corrosion protection requirements of the anchor depth.
Q:How seamless steel tube is formed?
Hot drawing or cold drawing. The so-called cold is the billet from the thick wall tube is not heated, oil lubrication, with a steel sleeve inside, gradually elongated. Hot drawing is to make the billet tube red, do such work, generally thick wall applicable.
