700℃ hydrofluoric acid corrosion protection for carbon steel – does anyone have good methods?
Thread Content
I’m facing a problem: corrosion protection using hydrofluoric acid at 700°C for carbon steel. There are solutions for temperatures below 150°C, but not for higher temperatures. The mixed flue gas contains fluorine; I need advice – should I replace the material, add a lining, or use a coating? Which one has the lowest cost for use over 3-5 years? Or are there better methods for preservation?
Can graphite equipment be used? There are many people in the forum who specialize in graphite anti-corrosion; you can consult them
Why is the temperature so high? That’s insane, lol
The key is whether there is moisture, and what the moisture content is
Graphite for corrosion protection – I’ve never come across it before; I’ll check it out
Can it cool down first? Since yours is of such poor quality, it seems I’ll have to conduct corrosion tests on my own.
