So why is the alloy pipe easy to rust after being pickled and passivated by the software?Difference and application description between H-beam and I-beamBayamo,Characteristics and application of galvanized pipeThe 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., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system,BayamoGh4105 alloy pipe, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Arjona,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, the more serious the disadvantages.What should we pay attention to in the production of alloy pipeAfter isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.

H-shaped steel groove is deep and thick, and can withstand forces in two directions. Pipe installation: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. 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. I-beam is widely used in buildings or other metal structures.Potential development, Remove defective pipes within the allowable length.→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.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, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.Home page recommendation,Classification introductionThe allowable deviation of vertical installation of galvanized pipe is mm per meter, and the allowable deviation above m is no more than mm. The allowable deviation of horizontally installed pipes is mm per meter.Because alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, when installing alloy pipes, we will use some flanges and elbows to fix them so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use,Bayamo42CrMo seamless pipe factory,BayamoReinforcement rapid turnover software, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.Bayamo, 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.Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition, when the circular cross section bears the internal or external axial working pressure, the bearing force is more symmetrical. Therefore
