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, HK and Hu respectively. Narrow flange H-section steel is suitable for beams or compression bending members,San RamonHow much is No. 14 I-beam, 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.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.San Ramon,There 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.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.Ananindeua,Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application.The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, curtain wall engineering, mechanical equipment and vehicle manufacturing.

Performance parameters and application scope of I-beamThe two ends of the steel produced by the seamless pipe manufacturer shall be cut into right angles and the burrs on the surface shall be removed,San Ramon45 small diameter seamless pipe, which is the raw material used by the seamless pipe manufacturer. The embryo prototube embryo needs to be cut by a cutting machine to form an embryo material with a length of about one meter, and the fuel used is often ethyne. Temperature control in the furnace is a very key factor.What are the requirements for alloy pipe construction accessoriesRange,Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application.Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, 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. The use of I-beam shall be selected according to the requirements of design drawings. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.

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 cheapestIt is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms, vehicles, highways, subways, steel structure plants and large warehousesHigh percentage of metal strength.The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width,Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.b. The professional two-sided arc welding processing technology can complete the electric welding at a good position,San Ramon12CR2MOG alloy pipe, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.
