It would be great to have a corrosion curve graph, thank you!

Is it a pipe? Valve? Heat exchanger or something else?

It’s about pipeline selection; CPCV is an option available. Considering the overall performance of the project, I’m thinking of using stainless steel.

I remember I shared it before. That said, in reality it is not recommended to use these materials, as local concentration may occur. All of these stainless steels are susceptible to pitting corrosion.

If you need to replenish the money, those with a stainless steel lining and PTFE coating are an excellent choice – there’s no problem at all!

Polyaniline has no issues and offers good value for money
