Determined by the shape, 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 % ~ %.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, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.Neba,There are several ways to clean galvanized pipesMixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Saarijarvi,NebaThe steel bar turning software is easy to use,Ways to obtain surface compressive stress characteristics of alloy tubes Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.a. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size,NebaHow much is 25 galvanized pipe per meter, specification and model of diameter and wall thickness especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.

Peak crackSince the s, with the rapid development trend of high-quality hot strip mill production and the development of electric welding and testing technology, the welding quality has been continuously improved, the types, specifications and models of welded steel pipes are increasing,Neba15CrMo seamless pipe manufacturer, and seamless pipes have been replaced in more and more industries. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the way of welding. Classified by production mode: classified by processing technology - electric arc welded pipe, resistor welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.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.How many?,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.Application scope of alloy pipeAs shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, 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, the structure of the I-beam has determined its torsional performance.

Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsMarketing Department, due to the inconsistent cooling speed and time of surface layer and core layer the temperature difference will be formed, resulting in uneven volume expansion and contraction, resulting in stress, namely thermal stress. Under the action of thermal stress, the starting temperature of the surface layer is lower than that of the core layer, and the shrinkage is greater than that of the core layer, making the core layer stretch. At the end of cooling, the surface layer is compressed and the core is stretched because the cooling volume contraction of the core cannot be carried out freely. That is, under the action of thermal stress the surface of the workpiece is compressed and the core is pulled. Peak crackNeba, Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.Application characteristics of I-beam:→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.
