What should we pay attention to in the production of alloy pipeI-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, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam,Le MullerPrice of 15CrMoG alloy pipe, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Le Muller, The surface of hot-dip galvanized parts is bright and beautiful.I-beam, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Port Louis, Judged as failing.Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange,Le MullerNo. 20 seamless pipe manufacturer, 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.

Frame line crackKeep the combustion supporting gas and use it reasonably to avoid fracture of the welding interface. Problems in the welding of steel wire mesh skeleton composite pipe are common, and the relevant limit accuracy or appearance change is not easy to change.Which one is better,At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.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.Generally there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.

I-beam, whether ordinary or light can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Welcome to inquire,Difference and application description between H-beam and I-beamWelded pipe refers to the steel pipe with joints on the surface,Le Muller12cr2mo1 alloy pipe, which is welded after the steel strip or steel plate is bent and deformed into circular, and what are the welding skills?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.Le Muller,Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.The utility model has the advantages that the axial force of the roll is small, the axial movement is small the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.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.
