Steel structure oceanic bridges are severely corroded; what methods can be used to address this issue?
Thread Content
Due to the high concentrations of ions such as Cl-, SO42-, and Mg2+ in seawater, as well as the influence of factors like sunlight, sea breezes, and marine organisms, the marine atmospheric environment is characterized by high humidity, high salinity, strong ultraviolet radiation, and strong winds, making it an extremely harsh corrosive environment. As a result, the corrosion of steel structures in seawater is extremely severe, as shown in the image below.
The material can withstand a certain degree of corrosion, and its surface is treated with anti-corrosion measures on a regular basis.
Thicken the coating using the anti-corrosion technique for ship surfaces. :lol
No, even for the bottom paint of a ship, regular maintenance is required; it’s not possible to take apart the steel structure just for maintenance……

Weather-resistant steel is used, eliminating the need for painting.

That’s really tragic. If it’s a new installation, one could consider using thermal spraying of aluminum followed by painting, or applying an anode coating. But given the current situation, just painting it will have to do; consider it as one year of service per coat applied
You’re overthinking it a bit; go and catch up on that quickly. P It is said that there’s a Luoyang Bridge in some place in Fujian, where oysters are raised on the bridge piers, making the structure extremely strong.
