stainless steel pitting in dearated conditions
stainless steel pitting in dearated conditions
(OP)
Is there a credible risk of chloride pitting or SCC in production lines/risers (flexibles with 316 and 304 carcass) and or produce water reinjection duplex lines (no sea water) handling deaerated produced fluids with chloride concentration of up to 100,000 mg/l, at temperatures up to 120°C.
It is assumed that since there is no seawater injection the produced fluids are oxygen free.

Most data will be for parent materials, but it is more likely that any welds will be the problem area.

In such a system I wouldn't touch an austenitic, at least the duplex grades have some resistance to SCC.
