Application characteristics of I-beam: Judged as failing.Escuintra,Precautions for galvanized pipe storage→ compared with the concrete structure, the I-steel structure can increase the service area by %,EscuintraA335p92 American standard high pressure alloy pipe, reduce the self weight of the structure by % - %,EscuintraHow many inches is welded pipe 42, and reduce the structural design internal force.Tutrakan,Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation. Small longitudinal crackDefects of alloy pipe and solutions:

Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe. It is to alloy the surface layer of steel so that the workpiece surface has the characteristics of some alloy steel. Aluminizing,EscuintraQ345B welded pipe manufacturer, chromizing, boronizing, siliconizing and so on are commonly used in production. 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, welded thin-walled pipe, transformer cooling oil pipe, etc.The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.superior quality,→ compared with the concrete structure, the I-steel structure can increase the service area by % reduce the self weight of the structure by % - %, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, the moment of inertia of the two main shafts on the section is quite different, which limits its application range. I-beam shall be selected according to the requirements of design drawings. In the structural design, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties, weldability and structural size of I-beam.

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.quality standard,Pass design Stair step plate (stair step plate) is a kind of stair used for platform with steel bar mesh. According to the installation method, it generally has two types: welding fixation and bolt (composition: head and screw). It is directly welded to the keel and does not need the side plate with step plate. It is relatively economical and durable, but it is not easy to disassemble, and holes are drilled on the side plates.What is the purpose of flat steelEscuintra→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.Defects of alloy pipe and solutions:What are the uses of I-beam?
