which can not only save resources, but also reduce consumption not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, reduce heating equipment, unique and convenient installation,Big hagui12Cr1MoVG alloy pipe factory, 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.I-beam is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'.Big hagui,Seamless pipe is made of steel block or solid pipe blank, and then made by hot rolling, cold rolling or cold dial. Seamless pipe plays an important role in China&#;s steel pipe industry. Seamless pipe production processes are relatively rich, generally according to the corresponding steps of processing and production. Peak crackMgandu,According to the theory of steel structure, the I-beam flange should be stressed, that is,Big haguiSpecial straightening and cutting machine for reinforcement, the I-beam should be standing rather than lying down.I-beamIt 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!

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.The correct and reasonable use of galvanized pipe can play a better role. The product can be widely used in the market because of its obvious performance advantages. Both strength and toughness are worth our choice. Let&#;s see what the specific uses are and what the acceptance standards are?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 -.Development Curriculum,The section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress 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.Performance parameters and application scope of I-beam

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.equipment maintenance ,Alloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher, and its performance of high temperature resistance, low temperature resistance and corrosion resistance. Ordinary carbon seamless tubes do not contain alloy components or have few alloy components. Alloy tubes are widely used in petroleum, aerospace, chemical industry, electric power, boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust. After hot-dip galvanizing of steel structure, it is equivalent to one-time annealing treatment, which can effectively improve the mechanical of steel matrix eliminate the stress during steel forming and welding, and is conducive to turning of steel structure.At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Big hagui,Performance parameters and application scope of I-beamAfter isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Application characteristics of I-beam
