The steel structure in the heating furnace area is severely corroded
Thread Content
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? The main reason is that the atmosphere in the vicinity contains large amounts of industrial gases such as hydrogen sulfide, sulfur dioxide, and carbon dioxide; when these come into contact with moisture in the air, they form a series of acidic waters. This will cause the steel structure to corrode more severely.
The main reason for the severe corrosion of the steel structures near the heating furnace is the presence of large amounts of industrial gases such as hydrogen sulfide, sulfur dioxide, and carbon dioxide in the atmosphere; these gases combine with the moisture in the air to form acidic water, thereby accelerating the corrosion of the steel structures. .
