Whether I-section steel is ordinary or light,TravnikInconel 718 Alloy Pipe, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.→ 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.Travnik,Defect detection of seamless pipe Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.Kapfenberg, Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRC→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.

Some applications of I-beam:Characteristics and application of galvanized pipe 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, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, 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.average method,Whether I-section steel is ordinary or light,Travnik108 welded pipe weight per meter, 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.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.Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects,TravnikCold drawn welded pipe manufacturer, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.

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.Excellent quality,H-section steel Cleaning: first, clean the grease, dust and other substances attached to the surface of the galvanized pipe after cleaning.The side length of I-beam is small and the height is large, so it can only bear the force in one direction.Travnik,What are the uses of I-beam? Small longitudinal crackI-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
