The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Fajado,According to the section shape, the steel pipe is divided into:What is the purpose of flat steelDimos Ilioupoli,→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Alloy tube is widely used in our daily life, which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together: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, physical and chemical properties in addition to the reasonable selection of materials and forming processes, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, copper aluminum, magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties.The second is the control of welding materials to ensure that the welding materials purchased are from formal channels, with quality assurance certificate and certificate, which meet the process requirements; The recovery of welding rod head shall be strictly controlled to ensure the flow direction and dosage; Welding materials shall be baked in strict accordance with the process, and the amount of one-time distribution shall not exceed half a day.The system is mainly composed of control box, finishing roller,FajadoHow much is a ton of welded pipe, pre leveling unit,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,FajadoTable of several inches corresponding to welded pipe, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Key technical characteristics of alloy pipe:The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.

The shape of I-beam is similar to that of H-beam. What is the difference between them?ranking,I-beam is widely usedWelded pipes with large or thick diameter are usually made of steel blank immediately, while small welded pipes and thick wall welded pipes must only be welded immediately according to nylon tape. After simple grinding and polishing, metal wire drawing is OK.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties,Fajadofifty × How much is a 100 galvanized pipe, weldability and structural size.Fajado,I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCThe shape of I-beam is similar to that of H-beam. What is the difference between them?I-beam, also known as steel 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.
