but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages. The defects can be removed by grinding with sand wheel but the remaining wall thickness must be within the allowable standard.Trinidad,Galvanized pipe has excellent corrosion resistance. Compared with traditional steel, its application life is longer. Secondly, this kind of pipe has strong resistance to baking. In case of critical situation, it will not lead to the collapse of building structure in a short time. In addition this kind of pipe also has a practical advantage, that is, it is more convenient and lighter when carrying out the construction and installation. The operators save time and labor when carrying out the construction, and the operation efficiency has been greatly strengthened. In this regard, it is not difficult to understand why the galvanized pipe is so favored by various construction units.→ 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.Category,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, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.Function of I-beam: where is I-beam mainly used?Advantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumption

What are the uses of I-beam?Installing the pipe structure means the complexity of some elements.Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, cost saving and light structural weight in all directions, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.knowledge,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,Trinidad30CrMo alloy pipe, 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.Ways to obtain surface compressive stress characteristics of alloy tubesAfter the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, and the solution time is min. Then dry.

The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid,TrinidadAlloy pipe GH2132,Trinidad6. How many kilograms per meter of sub welded pipe, sodium cyanide, etc., which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.Product range,According to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down. Completion of pipeline trench ground; Bricklaying of pipe shaft is completed.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.Trinidad,I-beam is widely used in buildings or other metal structures.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.
