The following steel structure is one located near a petrochemical heating furnace; it shows the condition after 4 to 5 years of use following anti-corrosion treatment. Why is the corrosion so severe?
It’s time for an upgrade, I guess; considering a replacement is the best option:lol
Is chemical desulfurization being used? There is a desulfurization salt that is extremely corrosive.
Looking at the pictures, it seems that the environmental humidity is quite high. Additionally, it is related to the acidic gases present in the smoke; moreover, the anti-corrosion measures for the steel structure are not adequate.
The high sulfur content in the furnace fuel results in high SO2 levels in the flue gases, and sulfurous acid causes corrosion after it rains.

The same is true for the steel structures of enterprises by the sea, where the rainwater is also acidic. It needs to be repaired every few years.
