Why C71500 (70/30 Cu-Ni) Tubes In Desalination Plants?
ASTM B111 C71500 (70% Copper, 30% Nickel) seamless tubes are a ideal material in desalination plants, particularly in Multi-Stage Flash (MSF) and Multi-Effect Distillation (MED) systems, due to their exceptional corrosion resistance, durability, and thermal efficiency in harsh seawater environments.
Key Reasons for Using C71500 Tubes in Desalination
*Superior Corrosion Resistance in Seawater:
Resists pitting, crevice corrosion, and stress corrosion cracking (SCC) in high-chloride environments.Forms a protective oxide layer that prevents further degradation.
*Excellent Biofouling Resistance:
Copper-nickel alloys naturally inhibit marine growth, reducing fouling and maintenance costs.
*High Thermal Conductivity:
Efficient heat transfer in condensers, heat exchangers, and evaporators, improving desalination plant performance.Better than titanium.
*Erosion & Cavitation Resistance:
Withstands high-velocity seawater flow (up to 3–4 m/s) without significant wear.
*Long Service Life & Cost-Effectiveness:
Lasts decades in desalination applications with minimal maintenance.
C71500 tubes are ideal for desalination plants because they offer the best balance of corrosion resistance, thermal efficiency, and cost-effectiveness in seawater environments.
