Materials resistant to methanesulfonic acid corrosion
Thread Content
The medium is methanesulfonic acid, the temperature is 170–180°C, and the pH is around 3. I would like to ask experts what material would be suitable in this case. . . Or who has the corrosion data for methanesulfonic acid: (
The temperature needs to be above 170°C; it’s difficult to install coils inside the equipment, as enamel coating isn’t suitable for such coils； The one lined with PTFE can’t be used at over 170 degrees, right?
The original poster had better clarify what type of equipment’s material is being referred to, such as pipes, towers, tanks, valves, or pumps.
Fluorine lining at 170℃ is no problem; the coil can also be lined with fluorine. If heat transfer issues need to be considered, PFA can be sprayed on with a thickness of 0.8~2mm. If enamel is used, jacketed heating is recommended; if stirring is required, evaporative stirring should be chosen. The advantage of evaporative stirring is that the heat transfer area does not decrease as the liquid level drops.
Expert, which manufacturers produce PFA coatings of better quality? Do you have their phone numbers?

This one. . . Using nickel-based materials would be more appropriate, right?
