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.Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe. It is to alloy the surface layer of steel so that the workpiece surface has the characteristics of some alloy steel. Aluminizing,DoboyWhat are the 25 galvanized pipes, chromizing, boronizing siliconizing and so on are commonly used in production.Doboy, The cold-rolled stainless steel pipe has the advantages of large yield coefficient,DoboyPrice of 15CrMoG alloy pipe, no expansion, bending and so on. In order to reach the health grade standard of stainless steel pipeline, the pipeline after cold rolling must undergo bright annealing, demagnetization, pickling, calibration and other procedures.The finished product has smooth surface, low friction coefficient, wear resistance and maximum temperature of ℃Mogadishu,Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe. It is to alloy the surface layer of steel so that the workpiece surface has the characteristics of some alloy steel. Aluminizing chromizing, boronizing, siliconizing and so on are commonly used in production.d. All machines and equipment in a production line can connect with the software of the computer data collection system to complete the timely transmission of data information, and the performance parameters in the production process are monitored by the central control room.Pass design
What should we pay attention to in the production of alloy pipeThere are many processes in the process of welded pipe processing, and every detail needs our attention. Welded pipes need to be treated by various processes before application. Heat treatment of welded steel pipe is an important link in the process of welding steel pipe. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, and the metal properties are controlled by changing the metallographic structure on the surface or inside of the material.All the cracks occur at -mm away from the edge below the alloy pipe,DoboyHow many inches is welded pipe 48, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.market price,The shape of I-beam is similar to that of H-beam. What is the difference between them?H-section steel is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight, and can save a lot of materials and construction time.The alloy tube can be hardened by induction heating, this kind of steel has been widely used as the material of rolling mill flap ball screw in rolling mill manufacturers. In addition to the excellent properties of cronidur steel, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment and its application range is expected to be further expanded.
Frame line crackoffer,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.The third is the welding machine, which must ensure reliable performance and meet the process needs; The welding machine must have qualified ammeter and voltmeter to ensure the correct implementation of welding process. The welding cable shall not be too long, and the welding parameters shall be adjusted when it is too long.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, 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.Doboy,I-beam, also known as universal beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate.The import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number, I-beam has no specific composition and performance series.
