silicon carbide heat exchanger
Thread Content
Silicon carbide is a new type of synthetic material that can resist any acid and alkali corrosion below 200 degrees and does not cause any pollution to the medium. Its thermal conductivity is 10 times that of glass, and it is pressure and temperature resistant. It is the best material to replace glass heat exchangers, glass-lined heat exchangers and graphite heat exchangers in the pharmaceutical industry.

Our experimental data is as follows:
Which manufacturer is it from? If you want to share information or advertise, please give me some useful information. Please introduce the extreme working conditions of silicon carbide heat exchangers at both hot and cold ends.
Silicon carbide heat exchangers are not afraid of heat resistance. As long as the heat resistance problem of the gasket and matching body part can be solved, silicon carbide can be used to more than 1,000 degrees. As for low temperature resistance: Personally, I think silicon carbide itself is relatively brittle and should not be used at very low temperatures. Generally, the working conditions must be considered in combination with pressure, and it is meaningless to talk about temperature alone. I am confident that the 200-degree silicon carbide, enamel, and tantalum heat exchanger can achieve more than 1MPa
I beg to differ, silicon carbide is not resistant to fuming sulfuric acid, and its resistance to HF acid is also limited. Moreover, the temperature must be combined with the concentration. Generally speaking, it can be resistant to any acid and alkali, which may easily mislead users.
