Classification introductionIt is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact, this cognition is wrong. H-beam and I-beam are different in shape!Guanajie,Welded thin-walled pipe: mainly used for making furniture, toys, etc. In recent years, thin-walled tubes made of stainless steel strip are widely used, such as high furniture, decoration, fence and so on.Function of I-beam: where is I-beam mainly used?Jijiga,Determined by the shape,GuanajieHow much is a 25 cm I-beam, 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 % ~ %.Alloy pipes are widely used in building materials, and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels, most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied.The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.

I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, which is called cold rolling. Due to the reorganization of steel crystal structure by cold rolling process so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.The chemical composition of cold-rolled ribbed strip is the same as that of hot-rolled smooth round strip. It is rolled at room temperature with hot-rolled smooth disc strip, high tensile strength (LL, ll, ll, etc.) is obtained, which has poor ductility and cannot be welded. If there are double-sided ribs and three-sided ribs the specification allows LL to be used as stirrup. The design value of strength is limited to n / mm?.With the development of steel structure buildings, only I-beam is not enough,GuanajieA335p9 high pressure alloy pipe, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.The cheapest,GuanajieWelded pipe wholesale manufacturer,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams.The utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required,Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃, and the solution time is min.

Mixed pass system. According to the characteristics of rolling mills and products, in order to give full play to the advantages of their respective systems and overcome their disadvantages, mixed pass system is often adopted, that is, the combination of more than two systems. For example straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole, etc.technological innovation,Mixed Scabs are distributed periodically, the higher the use value and economic value of this product. If its wall thickness is thinner, its processing composition will increase significantly, Secondly, the product technology produced by this seamless pipe manufacturer often determines its limitations. Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost, easy maintenance, elbow and similar products. You only need to add some spare parts. The expansion method of hot push can be used to process and manufacture large-diameter, thick wall and thin alloy steel pipes, and can not exceed the working capacity of thick wall pipes of machinery and equipment.Guanajie,Alloy pipes can be used for heating (cooling) projects.With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.Due to the unique performance of I-beam
