Small longitudinal crackThe 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., cross rolling pass system and mixed pass system. In addition I-beam can also adopt special rolling method.Kaparika, 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. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Banyo,It can withstand continuous moderate impact and can provide composite plates of various thicknessesX-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, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.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.

Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process,KaparikaHow much is hot dip galvanized pipe per meter,KaparikaPrice of 15CrMoG alloy pipe, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve. The surface of hot-dip galvanized parts is bright and beautiful.I-beam, whether ordinary or light, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Credit guarantee,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 -.Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.Dry processing technology: after passivation treatment, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.

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.Where can I find it?,Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.Galvanized pipe is often seen in our daily life, uniform zinc layer and no missing plating. Moreover, the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings. In addition, this product also has the characteristics of no dripping, strong adhesion, breaking the clean Legion and strong corrosion resistance. Even if it is used in some places where the environment is not good its service life is also very long, and it also has the characteristics of corrosion resistance. The standard anti rust thickness of hot-dip galvanizing can be maintained for more than years without repair. This is used in some suburban environments. However, in urban or offshore areas, standard urban or offshore areas can be maintained for years without repair. The products produced by our company must meet these requirements. Friends who need to order can call us directly.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties,Kaparika16Mn thick wall seamless pipe, chemical properties, weldability and structural size. 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.Kaparika,Alloy pipes can be used for heating (cooling) projects.I-beam features: the content of chromium carbon alloy is -%, and the macro hardness is - HRCStages needing attention in the production and manufacture of alloy tubes
