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,Los Angeles UnionWhich is easy to use for steel bar software, profiled steel plate, 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 settingLos Angeles Union,In view of the current market environment, especially in terms of construction or equipment manufacturing technology, the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life, even in a field that seems to have little contact. It will be applied in many construction projects. At the same time even in the depressed environment of the steel industry, the application situation and utilization rate of this kind of pipe are very high.I-beam, whether ordinary or light,Los Angeles UnionIncoloy825 alloy pipe, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Denov,Classification introductionI-beam also known as universal 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.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.

The utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required, 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,Los Angeles UnionHow much is the I-beam of 20, without hook.What are the uses of I-beam?Where can I find it?, The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, when the circular cross section bears the internal or external axial working pressure, the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes.Xhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes（ Φ ≥mm）； Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature.

Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, 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, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Scheme customization,Pass design Cleaning: first, clean the grease, dust and other substances attached to the surface of the galvanized pipe after cleaning.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 and the compression amount is adjustable; Straighten the width with staggered straightening wheels.Los Angeles Union,Passivation treatment operation of alloy pipeH-section steelWelded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, and their metal properties are controlled by changing the metallographic structure on the surface or inside of the material. During the heating and cooling process of structural welded steel pipe workpiece, due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.
