When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams.The flange of H-beam is of equal thickness, including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small), its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section.Hassert,In addition,HassertCustom welded pipe manufacturer, galvanized steel is more expensive than ordinary steel pipes, so installing them requires a lot of financial costs.What is the stainless steel passivation of alloy pipe?Castricum, The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.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, 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 national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange, wide flange and steel pile, whose codes are Hz,HassertSA213T91 alloy pipe, HK and Hu respectively. Narrow flange H-section steel is suitable for beams or compression bending members, while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel, W, IX and iy are not as good as H-section steel under the premise of equal weight.

Key technical characteristics of alloy pipeThe storage of galvanized pipes should pay attention to several points. The first is the storage location. It cannot be placed in the open air, because in the open air,Hassert15CrMo small diameter alloy pipe, not only the safety of various products such as theft, but also corrosion problems will occur. Open air sites are vulnerable to various extreme weather conditions. Large amounts of rain or snow will erode the zinc coating on the surface to the greatest extent, which may lead to rust of the product. The second is the details of storage. It is not directly exposed to the sun. It shall be cooled and dried and shall not be stored with corrosive articles.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,Application scope of alloy pipeIts heat sealing effect is remarkable. It can be directly buried immediately, but also reduce consumption not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole it is more convenient to use. It can also be used for the transportation of floor heating and hot springs. Miscellaneous scab

H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, etc.). Due to the reasonable section shape, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for settingInstallation conditions, Small longitudinal crackThere 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.I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.Hassert,Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.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.The key purpose of grinding and polishing alloy pipe is to moisten the surface, and the relevant limit accuracy or appearance change is not easy to change.
