The steel structure of the heating furnace area is seriously affected
Thread Content
The following steel structure is a steel structure near a petrochemical heating furnace, and its condition after 4 to 5 years of use after anti-corrosion. Why is corrosion so serious?
The chemical industry atmosphere contains a lot of sulfur and sulfides.
It's the same here. I think it's acidic corrosion from rainwater.
Whenever there is a corrosive medium, coupled with the action of water, electrochemical corrosion and damage will occur to the metal.
This is not difficult to deal with, but the difficulty lies in the cost.
For relatively harsh corrosive environments, most of them are indeed not done well. The main reasons are: first, the lack of understanding of such an environment ； Second, the relative investment is high and policymakers are unwilling to do so. Therefore, in such a corrosive environment, we must choose the right anti-corrosion materials and do the construction well.
The flue gas contains sulfur, which forms acidic gas when it meets water and corrodes peripheral equipment!
