The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.The flange of H-beam is of equal thickness, including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small), a group of vertical rolls must be added for rolling at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section.Malakatan,Cold. Peak crackDishna,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, expressed as No. ~ No., 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.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, mining and other industries to meet the provisions of cold,MalakatanHow much is a ton of I-beam now, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.So why is the alloy pipe easy to rust after being pickled and passivated by the software?

Application characteristics of I-beam:High percentage of metal strength.The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.For more,MalakatanHow much is spiral welded pipe, please check,What is the stainless steel passivation of alloy pipe? Judged as failing.Determined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam it can greatly improve the bearing capacity and save metal by % ~ %.

Nitriding: also known as nitriding, it is the process of penetrating nitrogen atoms into the surface layer of steel. At present,The pickling agent in the pickling process contains many acidic substances including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.Relatively high stability and high deformation resistance. The mixture is usually composed of hard fine aggregate graded aggregate with high sand equivalent, especially micro seal and polymer modified seal, which greatly increases the strength and integrity of the pavement.I-beam is widely usedMalakatan,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. Miscellaneous scabPlan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %
