Corrosion Inhibitors for Open Loop Sea Water Cooling Process
Corrosion Inhibitors for Open Loop Sea Water Cooling Process
(OP)
Hello,
We are having some corrosion issues with Duplex stainless steel grade 2205 piping used in the Gulf region for a sea water cooling process. We are yet to find the root cause of the corrosion and are presently investigating if it is a welding problem, or a problem with the material selection generally.
We have reference of other projects in the area using corrosion inhibitor dosing at the sea water inlet.
Does anyone have any experience to share of duplex 2205 corrosion in Gulf seawater, and use of corrosion inhibitors?
Thanks,
Tom

While the material choice of 2205 duplex is poor for the Arabian Gulf seawater, (high salinity, high temperature) it is a reasonable choice for castings used in the Baltic (near Sweden... look it up !)where both the salinity and temperature levels are more modest.
The minimum PREn of 40 for seawater, although most often reasonable, is not an iron-clad rule. Other factors come into play.
