Sea water corrosion of 316L
We must use a heat exchanger with Stainless steel 316l tube TO be low pressure condenser.
Tube side: sea water
Shell side: L.P.Steam at 140 C.
I know this type of stainless steel is not suitable at 140C, but what is your idea?

Hi Hassan,
You could consider PVDF which is OK to l40 degr. C but that's its upper limit, pressure wise.
There are the teflons, too. But am totally unsure of their pressure liminations.
All plastics are, however, lousy heat transfer agents but I have used, for chemical plants, PVDF heat exchangers quite a few times ... it being far more acid resistant than any stainless.
Food for thought, anyhow.

310S (improved type of 310 for welding) is suitable for exchangers.
Good luck.
