Use of SS316L and GRP for seawater service is also in practice. There is also an improvement of applying a Specail (paint) Coating inside
on SS316L for an extended life where seawater flow disturbances occur such
as downstream of valves.

Hi JUn,
stainless could be duplex (22 Cr%,...) or super duplex (25%) and that was
the intent. These two grades are used extensively in subsea or marine enviornment.
Cheers!

Stainless steel pipe material for sea water service?? Not in our plant.

Cupro-nickel material may be OK for US Navy application but in process/power plants where the coolant header (sea water service) is about 108 " NPS size - well you might have to rethink the economics of utilizing such material.
