TunapunaHow much is 20cm I-beam per meterWhy does the size decrease in use

Application characteristics of I-beamThe system is mainly composed of control box, pre leveling unit finishing unit and straightening unit.Tunapuna, Spiral seam submerged arc welded steel pipe (SY- for pressure fluid transportation is a spiral seam steel pipe used for pressure fluid transportation, which takes hot-rolled steel strip coil as pipe blank, often warm spiral forming and welded by double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding . After various strict scientific inspections and tests, it is safe and reliable to use. The steel pipe has large diameter and high transportation efficiency, and can save the investment in laying pipelines. It is mainly used for transporting oil and natural gas.GB No. I-beam is in height, in leg width and in waist thickness.Skopje,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Function of I-beam: where is I-beam mainly used?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, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.

I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, etc. The finished products shall be placed away from the processing site and stacked in the designated finished product warehouse. Ventilation and other facilities shall be provided in the storage environment.I-beamQuality inspection report,Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together:Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materials

After the passivation treatment of alloy pipe, ~ 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 % ~ %,TunapunaQuotation of welded pipe manufacturer, the solution temperature is ~ ℃, and the solution time is min. Then dry.Quotation sheet,The section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary,Tunapuna12Cr2MoWVTiB alloy pipe, H steel has its own advantages and disadvantages.Cold.Some applications of I-beam:Tunapuna,I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.Function of I-beam: where is I-beam mainly used?Key technical characteristics of alloy pipe
