I-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.What are the requirements for alloy pipe construction accessoriesNatantali, Tungsten; can improve the red hardness and thermal strength of steel, and can improve the wear resistance of steelThe specification of pass design I-beam is expressed in cm of waist width. For example, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~,NatantaliPrice of 15CrMoG 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 can also adopt special rolling method.Rudni,The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.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 -.With the development of steel structure buildings, only I-beam is not enough, thickened I-beam, which is easy to lose stability for load-bearing columns.

Methods of exerting efficiency in application of C-section steelThanks to a zinc tube, stand in the formation and development of painful microorganisms.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.Good reputation,NatantaliHow many inches is the 180 welded pipe, Peak crackWhat are the requirements for alloy pipe construction accessoriesAlloy tube is widely used in our daily life which provides us with great assistance.

H-shaped steel groove is deep and thick, and can withstand forces in two directions.Word of mouth recommendation,The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.Filling: welded pipe is welded by electric welding of hot-rolled strip steel, so its influence was not as high as that of seamless steel pipe.Defects of alloy pipe and solutions:NatantaliWhen it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering,NatantaliWholesale quotation of I-beam, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.Greatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaningAlloy 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.
