What material is required for heat exchange equipment that comes into contact with potassium hydroxide and lithium hydroxide solutions? For strong alkaline solutions of PH14, such as potassium hydroxide and lithium hydroxide solutions, what materials can be used to prevent corrosion?
Is there any expert to guide me? Where have all the experts gone?
Strong alkali, no other components? Carbon steel and stainless steel are both suitable
It is recommended to use stainless steel! !
In alkaline environments, temperature is also one of the key factors contributing to equipment corrosion. Given the specific temperature conditions, it is advisable to use nickel-based alloys or stainless steels with a high nickel content, or even pure nickel, zirconium, or Hastelloy. On the basis of proper material selection, appropriate coating treatments for corrosion protection should be employed, such as tetrafluoro coating； Also, choose an appropriate welding process; in short, take all measures possible to avoid corrosion caused by strong alkalis. As long as you have enough money, there is no problem that cannot be solved
