Laligua20CrMnTi alloy pipeWhat factors in processing will cause deformation of the workpiece

a. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies,Laligua16# I-beam quotation, and can meet a large number of customer regulations on the specification and model of alloy pipe.C - section steel is reliable and stable in stress, can be accurately positioned, and is resistant to impact and vibration Moreover, it has good versatility and combination, and has a variety of C-section steel and size selection to ensure its flexibilityLaligua,They are not affected by surrounding factors and processes,LaliguaHow much is the binding machine for binding steel bars, including corrosion.The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. The types of I-beam include hot-rolled ordinary I-beam Light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Catano,The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width the more serious the disadvantages. Miscellaneous scabThe sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned the surface of alloy pipe shall be clear of oil stains, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment and the reproducibility of the solution is good.

Frame line crackThe multi-al combination of reinforcement mesh welding machine and reinforcement mesh row welding machine based on PLC basic control. At present, the full-automatic mesh welding machine has the characteristics of simple operation, high control precision and easy to master the process of high-speed continuous welding.Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, which limits its application range. I-beam shall be selected according to the requirements of design drawings. In the structural design, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties, weldability and structural size of I-beam.Analysis project,The section of I-beam has good straight pressure and tensile resistance, 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.Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementWhen we carry out different projects, we must use different raw materials, 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:

Classification introductionWhere is good,After the passivation treatment of alloy pipe, ~ times of water cleaning, 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 % ~ %, and the solution time is min. Then dry. The tensile strength of seamless pipe is more than ~ times that of ordinary steel, the elastic coefficient is better than that of steel, and has good creep resistance,LaliguaHow much is a 40 galvanized pipe, corrosion resistance and seismic resistance.The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.Laligua,What should we pay attention to in the production of alloy pipeSo why is the alloy pipe easy to rust after being pickled and passivated by the software?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 % ~ %.
