Steel corrosion mechanism of different corrosive environment, use function and review method (Marine corrosion, acid corrosion environment of oil and gas, atmospheric corrosion, corrosion resistant, etc.)

Steel corrosion mechanism of different corrosive environment, use function and review method (Marine corrosion, acid corrosion environment of oil and gas, atmospheric corrosion, corrosion resistant, etc.); According to the concept of product life cycle Information planning methods on different corrosion mechanism side impact beams of corrosion resistant steel alloy composition planning, exercise, continuous casting, rolling and cooling control, welding, machinery processing skills, such as formation of corrosion resistant steel material system precision steel tube their common property in our country.
Steel is the key to the custom intelligent production skills. The whole process for custom production system; Iron and steel industry supply chain intelligent optimization skills; Steel intelligent planning and optimization skills; Steel structure function is forecasted, steel type merger and steel process parameters harmonious optimization control; Iron and steel Process large data space-time Shadowed synchronization and large data and common sense mixed mining analysis skills. According to the process of producing big data and produce high precision model of production experience and common sense; Users to customize product function parameters of dynamic consolidation used for the traction steel and steel products If you choose to ordinary steel tube, you buy steel tube and you receive pole will have a lot of error in determining the type and specification. Even in different parts of the side impact door beams steel tube, inner diameter or wall thickness, can make a big difference. Throughout the application process, this pipe will no doubt have a lot of difficulties. But the precision steel tube is different. This kind of steel pipe specifications are very strict.
Precision steel tube, although impossible, pipe specifications are accord with actual specifications per level. But precision steel tube can control the measurement error in small a category. In general, this is not easy to determine error, is greater than the two standards of the enterprise, is enough for most fields.
As you all know, steel pipe in outdoor in the long run, or what is the friction, air oxidation layer on the surface of the stainless steel plate will be destroyed, then in the damp cold gas oxidation rust in the natural environment. Therefore, steel pipes should be placed in a sealed area as much as possible. And precision steel pipe has the advantage, because the surface is not easy to oxidation, the composition of precision steel tube of raw materials is inseparable. Steel pipe is produced on the surface of a thin, strong, is exquisite, the stability of the rich chromium oxide film air, can avoid oxygen molecules to penetrate and air oxidation, antirust ability to work. Weak aluminium coated steel tube corrosion resistance of precision steel tube that transition film part will point for self-excited oscillation and the corrosion, reflected by the generation of pores can form content close strong corrosion of chlorine ion solution, so as to speed up the corrosion.
In addition, the stress corrosion cracking of stainless steel plate internal damage transition film on the surface of the stainless steel plate. Therefore, precision steel pipe surface should be clean and keep in the corresponding level, to increase the service life. Arrange function dynamic guessing skills.
