The side length of I-beam is small and the height is large, so it can only bear the force in one direction. Small longitudinal crackScutai,External steel bonding reinforcement method is a more traditional reinforcement method. The utility model uses an adhesive to paste the steel plate or reinforcement mesh on the cracked part of the wall to achieve the purpose of reinforcement. The commonly used adhesive is usually epoxy resin. This method is simple and fast in construction and has little impact on production and life. Basically the bearing capacity of the wall can be greatly improved without changing the shape and internal use space of the components. It is mainly applicable to the reinforcement of walls that do not allow to increase the section size of original components, but can greatly increase the section bearing capacity.What is the stainless steel passivation of alloy pipe?Itaquaquecetuba,Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Application characteristics of I-beam

After isothermal quenching treatment,ScutaiHow much is DN25 galvanized pipe per meter, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment. Pickling stainless steel pipe. When removing grease, rust prevention, oxide layer free iron and other dirt, the surface shall be treated with silver to evenly slow down the pickling surface, prevent metal corrosion and hydrogen embrittlement and inhibit fog production.The flange of H-beam is of equal thickness, including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small) a group of vertical rolls must be added for rolling at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section.consumption,Performance parameters and application scope of I-beamPlan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %C-section steel has uniform zinc layer, smooth surface, strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, corrosion resistance and durability. It is a kind of stronger protection.

What is the purpose of flat steelmarket, Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason,Scutai40Cr alloy pipe, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, 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, etc.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.I-beam is widely usedScutai,The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle,ScutaiHow much is the reinforcement contract for one square meter, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width
