Selection Guide
Comparison Insights
Performs Better Than
- Carbon steel in seawater cooling service
- Many copper alloys for biofouling resistance
- Standard stainless grades in certain seawater condenser duties
Considerations
- Higher cost than carbon steel
- Velocity and design limits must be respected in seawater systems
Technical Notes
Cupro Nickel Products
Cupro Nickel alloys are preferred for seawater and brine service due to corrosion and biofouling resistance.
