316L S.Steel flow sensor on seawater filled Copper Nickel pipe
316L S.Steel flow sensor on seawater filled Copper Nickel pipe
(OP)
Hi everyone,
I have a corrosion related question..
In our Yacht project, we have been supplied by our HVAC subcontractor with a set of:
ifm SI5000, flow sensors.
These sensors will be mounted on CuNiFer pipes and measure the sea water flow.
I am concerned about the fact that the sensor (316L) will be screwed in a CuNiFe nipple on the sea water pipe and the threads will be subject of galvanic corrosion (Stainless Steel + Copper Nickel + Sea water).
Can you please advise, would a electric isulation of the two threads will be enough?
Thanks

The 316 will be susceptible to bio-fouling and corrosion.

However, also agree with Edstainless, best to avoid 316 for marine applications. We have had serious problems with pitting corrosion of SS316 on our project in the gulf. Warm water + high salinity.
