Determined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, and connect the switching power supply, If the current flows from the positive stage to the negative stage, excavate part of the gravel cushion (if it is non gravel fillerMost of the original bridge decks lack a stable and solid base course with poor integrity. It is necessary to clear the original bridge deck, replace it with gravel filler and tamp it), and the load can be evenly dispersed so it has good bonding and anchorage with the concrete, which obviously improves the performance of the reinforced concrete structure. According to the practice test, the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh.When we carry out different projects, we must use different raw materials,Aitos16Mn seamless pipe manufacturer, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:Vijayawada,The utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. I-beam is mainly divided into ordinary I-beam,Aitos13CrMo44 alloy pipe, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams.The surface of cold galvanized layer is smooth, dense and uniform. It has good mechanical properties and corrosion resistance. The consumption of hot-dip galvanized coating is between % - %. The galvanizing process is complex, but the thickness of single-sided coating, surface coating and double-sided coating is different, so the thin-walled pipe shall be galvanized. The zinc coating has strong protection and corrosion resistance.So why is the alloy pipe easy to rust after being pickled and passivated by the software?Honest service, Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.Because alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, when installing alloy pipes we will use some flanges and elbows to fix them,AitosHow much is DN50 galvanized pipe, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.I-beam is widely used

I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.quality standard,Function of I-beam: where is I-beam mainly used? According to the pipe wall thickness, pipes made of relatively thin materials such as steel strip can be welded with high frequency, and some thin-walled pipes can be welded with shielding gas; Pipes with wall thickness more than mm can be welded by hand.Function of I-beam: where is I-beam mainly used?Aitos,→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.The utility model has the advantages that the axial force of the roll is small the axial movement is small, and the working slope is not required,Application characteristics of I-beam:
