It 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 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.Saguarragrand,Wire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin, which is mostly used after coating or galvanizing, and cold bending test is required.Generally, there are many passivation methods for alloy tubes the common ones are high temperature passivation or sodium cyanide passivation.Vyskov,What are the requirements for alloy pipe construction accessoriesThe system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption,SaguarragrandHow much is 200 welded pipe per meter, 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, meet the requirements of thermal insulation and cold protection, reduce heating equipment, 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.

Application characteristics of I-beam:Seamless pipe has a high position in steel pipe, and there are many large factors. The main usage has accounted for more than % which is applicable to all walks of life. Seamless pipe factories in China are widely produced. At present, the number of factories in China is also increasing every year, which is determined by the nature and production conditions of seamless pipe. The common production processes and processes are more complex.I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates,Saguarragrand40Cr seamless alloy pipe, cast stones, rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Safety and health,The import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.index,Saguarragrand12Cr2MoWVTiB alloy pipe,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.Classification by useAdvantages of using I-beam: reduce maintenance cost, improve equipment operation rate, reduce wear reduce equipment capacity and increase power consumptionSaguarragrand, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.
