The lead-lined pot is experiencing corrosion; I would appreciate it if experts could analyze the causes of this corrosion, and it would be great if they could also describe the form of the corrosion Dielectric hydrofluoric acid
The cause of corrosion is unknown. In terms of material selection, in theory, carbon steel can be used in areas where hydrofluoric acid is present at low temperatures (below 66 degrees) and with low flow rates; alloy 400 or composite sheets can be used in areas with higher temperatures or faster flow rates. As a last resort, C276 can be used.
Bro, glass-lined steel can’t withstand hydrofluoric acid. Where did you buy this from? It’s really terrible – they don’t even have this basic knowledge, just trying to make money!
:This is really serious; let me apply a layer of C276 for you
For requests like this, it’s best to specify the material, pressure, temperature, medium, flow rate, and other detailed operating conditions of the environment; otherwise, there isn’t enough information
In most cases, carbon steel is sufficient; gaseous forms are acceptable, but those containing water are not. Ordinary hydrogen fluoride cylinders and buffer tanks are made of carbon steel. However, there is no need to use enamel, as it would be wasteful – after all, enamel reacts with hydrogen fluoride (especially when it contains water)
You’ve seen it wrong; it’s a lead-lined pot, not enamel-coated. Enamel-coated products cannot be exposed to fluoride ions
