Difference and application description between H-beam and I-beamStages needing attention in the production and manufacture of alloy tubesTarachin,Galvanized pipe is a kind of light thin-walled steel pipe with hollow square section, also known as steel cold-formed profile. It is a section steel with square section shape and size, which is made of Q hot-rolled or cold-rolled strip or coil as the base material, cold bending and high-frequency welding. In addition to wall thickness thickening, the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe.The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate.Kauhajoki,Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %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, H steel has its own advantages and disadvantages.Alloy pipes can be used for heating (cooling) projects.

Alloy pipes can be used for heating (cooling) projects.Emulsified asphalt emulsion is also easy to use on the mobile slurry seal paver. It is necessary to mix on the machine and use additives for chemical control for maintenance. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.Safety production,C-section steel has uniform zinc layer, smooth surface, strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer,TarachinSpecial straightening and cutting machine for reinforcement, and the zinc content on the surface is usually -g /? It has long service life, physical and chemical properties, in addition to the reasonable selection of materials and forming process,Tarachin25 welded pipe is more than one meter, 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.The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. 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 ~ mm, and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.

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 ~, 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.recommend,Carburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, and then after quenching and low-temperature tempering, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.They are not affected by surrounding factors and processes, including corrosion.In order to make the steel pipe workpiece have the required mechanical,TarachinQ345 straight seam welded pipe, 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, the heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties.TarachinClassification introductionAfter isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.
