Material that is resistant to 40% hydrogen fluoride and has good thermal conductivity
Thread Content
I would like to ask everyone, is there such a material that can withstand 40% HF and has relatively good thermal conductivity? Thank you!
Is it a heat exchanger? If it is a heat exchanger, it is recommended to use graphite heat exchanger.
For metal, Monel or C276.
Maybe the concept is slightly adjusted, the thermal conductivity is directly proportional to the heat exchange area. If the space is available, the thermal conductivity can increase the heat exchange area. But it solves the problem of anti-corruption, which may be the most important.
It can be seen that there are many conditions for use, but the key is that there are no reliable use cases. If not, you can do some experiments and actual verification, which should be safer.
Just use stainless steel 304, and it is more cost-effective to replace it after two years. The price of a titanium alloy reboiler is several times different from that of a stainless steel reboiler, and the corrosion degree and age are not much different than that of stainless steel.

non-metallic words: Silicon carbide and graphite can be considered. For metals, N04400 is mentioned in foreign materials and is also mentioned in corrosion manuals.
