Stainless steel pipe fitting is not easy to rust and the composition of stainless steel has a great relationship. Stainless steel in addition to the composition of iron, there are chromium, nickel, aluminum, silicon and so on. General stainless steel chromium content is generally not less than 12%, high or even up to 18%. Steel added chromium and other elements, you can change the performance of steel, such as steel, such as the molecular structure is more uniform in the steel surface is more likely to generate a layer of dense oxide protective film, etc., thereby greatly improving the ability of stainless steel corrosion resistance. So stainless steel can resist fire, water, acid, alkali and a variety of solutions to its corrosion, no rust. Scientists have found that the more uniform the internal structure of steel, the more closely connected components, the more difficult the corrosive invasion, coupled with the surface and attached a layer of oxide protective film, like steel to wear armor, natural It is not easy to rust.
The Requirements of Stainless Steel Pipe Fittings in Bridge Construction
1) durability requirements. Bridge in the marine environment, the design life of 120 years, the higher the durability requirements.
2) Save maintenance costs. The use of stainless steel pipe in the course of the use of the bridge without the need for regular maintenance, saving a lot of maintenance costs.
3) security requirements. Wind tunnel tests show that the lighter pylon is susceptible to vortex-induced vibration, which can also cause large-amplitude cable vibration. Therefore, in order to improve the aerodynamic performance of the pylon, the pylon is filled with concrete in the stainless steel pipe Stainless steel tube concrete structure.
4) looks beautiful.
