Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, which limits its application range. I-beam shall be selected according to the requirements of design drawings. In the structural design, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties, weldability and structural size of I-beam.I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.Gostivar,Characteristics and application of galvanized pipeX-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.San-Fernando,Application scope of alloy pipeH-section steelI-beam is widely used
c. quality inspection is carried out for alloy pipes, so that the whole process of steel pipe processing is under reasonable inspection and supervision, and the product quality is reasonably guaranteed.Classification by wall thicknessIn order to make the steel pipe workpiece have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming processes, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, aluminum, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties.How much does it cost?,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,GostivarHow much is the I-beam per ton, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment,GostivarHow much is a welded pipe, 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.The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system alloy steel pipe stimulates important effects.
I-beam is widely used in buildings or other metal structures.Finance Department,I-beam, also known as steel 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.Are there many welded types of mesh produced? According to the welding type and overall improvement, the difference between the reinforcement mesh and the welded mesh is not particularly large. It is still due to the scattered quality of the southern city. From the perspective of development to the longitudinal and transverse interleaving devices of the reinforcement mesh, the bound or welded mesh has better application quality.H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam,GostivarHow much is a ton of 25 galvanized pipe, channel steel and angle steel.Gostivar,I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.Application characteristics of I-beam Miscellaneous scab
