The import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number, I-beam has no specific composition and performance series.→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.Toluca,Seamless pipeAdvantages of using I-beam: reduce maintenance cost, reduce downtime, reduce wear, reduce equipment capacity and increase power consumptionKeuru,Classification introductionAs shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market,Toluca40CrNiMo alloy pipe, the structure of the I-beam has determined its torsional performance.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, medium and narrow flange I-beams.

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, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space. East West derusting: if the galvanized pipe surface is rusty, the manufacturer will choose East West derusting and polish it with a steel wire brush→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %,TolucaHow much is 50 galvanized pipe, and reduce the structural design internal force.consumption,I-beam: national standard * what is the wall thickness of I-beamAlloy pipes can be used for heating (cooling) projects.What are the uses of I-beam?

In order to make the welded pipe have the required mechanical, physical and chemical properties,Toluca40Cr alloy pipe manufacturer, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition, the mechanical, physical and chemical properties of aluminum, copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.management,Difference and application description between H-beam and I-beam As long as the pipe material is high-strength alloy steel, including alloy steel pipes with temperature resistance, pressure resistance, wear resistance and low temperature resistance, the welding process shall be focused on preventing the tendency of martensite structure and cracks due to welding high-temperature operation. The general process requirements are that the welding rod shall be selected and baked as required and sent to the welder for use. The oil and water shall be removed before welding on both sides of the weld Rust and sundries shall be removed and cleaned. The welding line energy shall be as small as possible to minimize the swing during the welding process. The arrangement of the last weld shall have annealing effect on the heat affected zone as far as possible. Slow cooling after welding, cover with asbestos cloth, etc.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, and the performance parameters in the production process are monitored by the central control room.Toluca,Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementFunction of I-beam: where is I-beam mainly used?Under the action of thermal stress because the initial temperature of the surface layer is lower than that of the heart and the shrinkage is greater than that of the heart, the heart is pulled. At the end of cooling, because the final cooling volume shrinkage of the heart cannot be carried out freely, the surface layer is compressed and the heart is pulled. That is under the action of thermal stress, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the uneven plastic deformation caused by thermal stress during cooling, and the greater the final residual stress. On the other hand, due to the change of microstructure during heat treatment, i.e. the transformation from austenite to martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume, and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. The final result of the change of tissue stress is the tensile stress on the surface and the compressive stress in the center, which is just opposite to the thermal stress. The microstructure stress is related to the cooling rate shape and chemical composition of the workpiece in the martensitic transformation zone.
