Materials of Construction and High Chloride Corrosion

What is the ​most reliable ​material in a ​high chloride ​content, from ​15% to 25% ​environment and ​at temperatures ​from 60 C to 90 ​C?  ​Sandvik 2507 ​looks a real ​possibility. ​Would you ​consider  ​Carbon Steel + ​Coating as a ​cheaper ​alternative? ​

1. Having worked long time in hot climate I have learned that PVC has 60 degrees C as maximum temperature,,,

2. CS with PP or PVC or rubber lining is the cost effective solution.

3. Pending the pressure I would consider PP instead of anything containing iron. Chloride concentration is high!

4. Better go to choose SS304/316 material  but getting the coating (PVC) over Carbon steel shall also be a good and economical option.

   1. Coating of RC Butyl/EPDM over CS shall be more economical

      .

5. Sandvik 2507 resists at chloride concentration 0,2%. So, it does not fit on your occasion. 

6. May you can use FRP, BTW what's pressure rating. Hastelloy  should also work, CS with Coutchuc (natural rubber) can also done.

    

7. Hatelloy would be the reliable material.

8. maybe consider another product than chlorine...?

9. Coating and carbon steel will not have the same flexibility at temperature deviation, so coating will peel off, except if it will be caoutchouc (rubber) coating, which is proposed by me.
