The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.When we carry out different projects,FloridaPrice of 15CrMo alloy pipe, 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:Florida, The finished products shall be placed away from the processing site and stacked in the designated finished product warehouse. Ventilation and other facilities shall be provided in the storage environment. 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.Joliette,The shape of I-beam is similar to that of H-beam. What is the difference between them?Defects of alloy pipe and solutions:At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.

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,Florida40Cr seamless alloy pipe, when installing alloy pipes, we will use some flanges and elbows to fix them, so as to ensure that the raw materials can be fixed very well. Therefore,Florida20 seamless pipe manufacturer, 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.Wire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin, which is mostly used after coating or galvanizing and cold bending test is required.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, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.Development Curriculum,It can withstand continuous moderate impact and can provide composite plates of various thicknessesPass designI-beam

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Latest quotation, Miscellaneous scabThe use of hot dip galvanizing has expanded with the development of industry and agriculture. Therefore hot-dip galvanized products have been widely used in industry (such as chemical equipment, petroleum processing, marine exploration, metal structure, power transportation, etc.) agriculture (such as sprinkler irrigation, heating room), construction (such as water and gas transportation, wire casing, scaffold, house, etc.), bridges, transportation, etc. because hot-dip galvanized products The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.Florida,I-beam is widely used in buildings or other metal structures.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.Application scope of alloy pipe
