When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, so it is very popular in the field. When people carry out the construction of alloy pipe project we will apply it, there are many things that must be paid special attention to. Let&#;s take you to know:The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, 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.Komandador, There is a great demand for welded steel mesh in China&#;s market.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.zaire,The side length of I-beam is small and the height is large, so it can only bear the force in one direction.Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition, when the circular cross section bears the internal or external axial working pressure, most seamless steel pipes are round steel pipes.

Mixed pass system. According to the characteristics of rolling mills and products, in order to give full play to the advantages of their respective systems and overcome their disadvantages, mixed pass system is often adopted that is, the combination of more than two systems. For example, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole, etc.They are not affected by surrounding factors and processes, including corrosion.What should we pay attention to in the production of alloy pipeApplication process,It can withstand continuous moderate impact and can provide composite plates of various thicknessesI-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.When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.

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.Respect for customers,Advantages of using I-beam: reduce maintenance cost, reduce downtime,KomandadorHow much is 600 welded pipe per meter,KomandadorHow much is a 32 galvanized pipe, improve equipment operation rate, reduce wear,KomandadorHow many kilograms per meter of 100mm welded pipe, reduce equipment capacity and increase power consumptionThe 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.Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Komandador,At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.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.
