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
