We are looking at using PCHE (heatric) for a clean gas/cooling water service operating at temperature above 50 deg C (but below 100 deg C) in an offshore marine enviroment.
From what I understand, 316L is not accpetable for application above 50 degC in an offshore marine environemnt and due to this cause, application of SS316L, Duplex and Super Duplex have been limited to 50, 100 and 100 deg C respectively.
For the service and temperatures above, vendor has offered the headers constructured of duplex material, but the core is retained as 316L. The core, will be exposed to marine environment.
Can someone please comment further?
