Governing Standards for Brine / Sodium Chloride Solution Service

ASME B16.34NORSOK M-001 (for produced water offshore)ASTM A890 Grade 5A (super-duplex)

What to Avoid in Brine / Sodium Chloride Solution Service

SS 316L in hot or concentrated brine
Carbon steel without coating and cathodic protection
Standard cast iron valves

Service Considerations

PREN ≥ 40 for high chloride brine at elevated temperature
Crevice-free design - remove all gasket crevices and threaded connections
Produced water brine: NACE MR0175 if H₂S present
Desalination: cathodic protection for submerged fittings
