Potassium chloride solution material
Thread Content
What material should I use for potassium chloride solution?
316L or titanium material. . . . . . . . . . . . .
We are using 304, but recently we found it was leaking. Our environment may be more complicated. It contains not only potassium chloride but also ammonium chloride and sodium chloride. The temperature is 120. We are going to replace it with titanium. I don’t know if 316L will work.
Use duplex stainless steel 2507, or glass lined!
Chloride ions are very corrosive. 304 and 316L can be used in the short term, but they are not recommended. It is recommended to consider the opinions above.
I don’t know under what conditions you are using it, such as temperature and pressure, and what other materials are in this solution. However, I suggest you try FRP or steel-lined PE\PP\PO pipes. Of course, you can also use PPR pipes directly.
Duplex steel 2205, lined with enameled, lined with PP, lined with PTFE, etc. can be used
