Key Advantages
- Unrivaled Saltwater Resistance: Withstands pitting, crevice corrosion, and biofouling in marine environments (ASTM G52 compliance).
- High Thermal Conductivity: 29 W/m*K (2x higher than stainless steel), ideal for condensers and heat exchangers.
- Seamless Integrity: Cold-drawn and annealed processes ensure zero defects and uniform wall thickness (±3%).
- Long-Term Durability: Service life exceeding 25 years in seawater applications.
Applications
- Marine Condensers & Heat Exchangers
- Desalination Plant Pipelines
- Offshore Oil & Gas Cooling Systems
- Chemical Processing Equipment
