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 specifications of the first two are -, that is the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Some applications of I-beam:Hotron, Ditch cover plate (ditch cover plate) is widely used in municipal roads, garden facilities, residential quarters, schools, stadium pipes and other places.I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.Letlhakane, The defects can be removed by grinding with sand wheel,HotronHow much is a welded pipe, and the power is large, generally about KW, and PLC control is mostly used.

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 sleeves 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. Seamless tube has high elasticity, can be reused on mechanical equipment, no memory, no deformation, anti-static.With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.Work courses,Main uses: as a finished material flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.Application characteristics of I-beam:Key technical characteristics of alloy pipe

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,After the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ % the solution temperature is ~ ℃, and the solution time is min. Then dry. The reinforcement on both sides of the inverted beam extends into the beam respectively, and the anchorage length of the reinforcement is the same as that of the reinforcement,Hotronfifty × How much is a 100 galvanized pipe, without hook.Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.Hotron, Peak crackDue to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main sleeves 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 small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.
