Dear experts, for 104% fuming sulfuric acid, that is, fuming sulfuric acid, what materials should be used for its transportation and storage? Except for non-metals, thank you
At room temperature, 98% concentrated sulfuric acid can be handled with carbon steel; it’s not clear whether carbon steel can be used for fuming sulfuric acid, but SUS304 is definitely suitable for it. Assuming your temperature is at room temperature, right?
Normal-temperature carbon steel is sufficient, but in practical use attention should be paid to changes in acid concentration (local variations can also cause localized corrosion; avoid acids with high corrosivity).
What is the operating temperature? If the temperature is not high and the conditions are not stringent, carbon steel can be used
Here, the operating temperature for sulfuric acid with smoke is 30°C, and the material used is carbon steel； Attention should be paid to the equipment insulation, particularly in the discharge area at the bottom of the tank; it is advisable to regularly inspect the insulation to ensure its proper function.
Concentrated sulfuric acid exhibits self-passivation, and it can be stored in ordinary carbon steel containers. Pay attention to temperature changes and regularly check the wall thickness of the tank.
