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.When we carry out different projects, we must use different raw materials, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:Neba, There is a great demand for welded steel mesh in China&#;s market. Small longitudinal crackNegombo,Application characteristics of I-beam:Methods of exerting efficiency in application of C-section steelDue 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.

Performance parameters and application scope of I-beamThe pollution of the joint causes the welding cracking. The composite pipe welding is an accurate work. If it is not done well, but also lead to work efficiency, rework and restart, and waste financial resources.Passivation treatment operation of alloy pipePursuit of excellence,→ 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.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.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.

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.For more, please check, Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason,NebaHow much is a meter of welded pipe,NebaGh2747 superalloy tube, 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,NebaAlloy pipe 12Cr1MoVG, etc.From the comparison of the monthly summary apparent consumption data information of galvanized pipe and the real estate sales data information from to this year, which not only shows a positive correlation in the overall new trend, but also significantly conforms to the fluctuation direction of the monthly development trend.Application characteristics of I-beam:Neba,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.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.Carburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, and then after quenching and low-temperature tempering, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.
