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.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.Italy,In hardware, you can choose an incomplete performance outside the product. Some construction experts claim that if there is a mechanical effect on these products,ItalyWhat is the outer diameter of 80 welded pipe,The shape of I-beam is similar to that of H-beam. What is the difference between them?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.Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.

Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs. Seismic and cracking performance the longitudinal and transverse bars of the welded reinforcement mesh form a network structure, so it has good bonding and anchorage with the concrete, and the load can be evenly distributed, which obviously shows the seismic cracking performance of the reinforced concrete structure. According to the actual test, the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh. It greatly reduces the unnecessary cost generated manually in the construction and shortens the construction period. The use of reinforcement mesh is simple and convenient, and the reinforcement mesh is convenient for transportation. Miscellaneous scabmanagement Remove defective pipes within the allowable length.c. quality inspection is carried out for alloy pipes, so that the whole process of steel pipe processing is under reasonable inspection and supervision, and the product quality is reasonably guaranteed.→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection,Italy16Mn thick wall welded pipe, and saves about % of the manufacturing cost of steel structure.

Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.Process inspection,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. Platform reinforcement mesh is a widely used reinforcement mesh product, such as industrial maintenance platform, berm, etc. this kind of reinforcement mesh is widely used in industry, municipal administration, electric power, coal mine and other fields, and has the strongest resistance to surface impact, especially the reinforcement mesh with a cross bar spacing of mm has a strong ability to resist lateral impact.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 ~,Italy15CrMoG alloy pipe, 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 also known as universal 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.I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.
