H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Milaguana, Straight seam electric welding steel pipe (yb- is a steel pipe whose weld is longitudinally parallel to the steel pipe. It is usually divided into metric welded steel pipe,MilaguanaHow much is 90 galvanized pipe, welded thin-walled pipe, transformer cooling oil pipe, etc.The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.Nsukka,Classification introductionWhen selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Requirements of alloy tubes for low and medium pressure boilers

Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency, low metal material consumption, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore, it is widely used Welded steel mesh, a new form of reinforcement, and the macro hardness is - HRCSafety production the hardness of chromium carbide alloy is V,The side length of I-beam is small and the height is large, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumption

Key technical characteristics of alloy pipe:Administration,Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, which makes it very limited in the scope of application. In order to ensure the welding quality of pipes, welders shall be trained, tested and qualified. In addition to the basic theory, the welder should consider the operation skills. The pipe welding process may include several postures of overhead welding,Milaguana45# thick wall seamless pipe, vertical welding and overhead welding (when the pipe cannot rotate). The size of current should be selected to take into account the formation of vertical welding and overhead welding (some pipes are not very large, and the current cannot be adjusted in the middle of one formation). In the process, the stability and formation of arc should be controlled, It can swing properly, and the forming shall be well combined with the necessary swing.Pass designMilaguana,MilaguanaHow much is galvanized pipe DN65 per meter, Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, 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.Requirements of alloy tubes for low and medium pressure boilersI-beam
