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,MoreliaHow many inches is the 219 seamless pipe, 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, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Stages needing attention in the production and manufacture of alloy tubesMorelia,Compared with manual binding, the concrete can be poured eliminating the links of reinforcement on-site cutting, placing one by one and binding. It can save % - % of working hours, greatly accelerate the construction progress and shorten the construction cycle.Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Ondo,The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction,Morelia40Cr precision alloy tube, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.With the development of steel structure buildings, only I-beam is not enough, thickened I-beam, which is easy to lose stability for load-bearing columns.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.

When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.First, we can clean the outer surface of the welded pipe with solvent or emulsion. This method is very effective for cleaning the oil stain, dust and other organic matters on the surface of the welded pipe.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 -.Inspection requirements,When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project there are many things that must be paid special attention to. Let&#;s take you to know:What are the uses of I-beam?b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.

What are the requirements for alloy pipe construction accessoriesSafety production, Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, and its weight is only one fifth of that of anti steel.Alloy pipes can be used for heating (cooling) projects.Morelia,I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows: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 -.Whether I-section steel is ordinary or light,Morelia254SMO alloy pipe, 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. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.
