Seawater Desalination Titanium Plate Recycling

Titanium plates are used in seawater desalination for: MED evaporators, RO high-pressure pump valves, and thermal desalination condensers. Major brands include Italy's De Nora, Japan's TOSOH, and Russia's VSMPO. DONGSHENG recycles nearly all desalination titanium plates from these brands at premium prices.

Key Parameters for Desalination Titanium Plates

Corrosion Resistance: Annual corrosion rate in 80°C seawater <0.01mm (vs. >1mm for stainless steel)

Strength: Tensile strength ≥345MPa (Grade 2); Ti-6Al-4V reaches 895MPa

Thermal Conductivity: 17 W/(m·K) (better than stainless steel, lower than copper alloys)

Wall Thickness: Heat exchange tubes: 0.5–1.2mm; Tube sheets: 10–30mm

Lifespan: ≥20 years (over 4× longer than stainless steel)

Application Scenarios

MED Evaporators: Titanium plates serve as tube sheets/vessel linings, resisting 90°C high-salinity brine. Lifespan >25 years.

RO High-Pressure Pump Valves: Ti-6Al-4V alloy parts withstand 6MPa seawater impact.

Thermal Desalination Condensers: Titanium heat exchange tubes prevent chloride corrosion, ensuring water purity.

Global Brands

De Nora: Patented welded titanium clad plates for evaporator vessels.

TOSOH: Ultrathin welded titanium tubes (0.5mm wall) for higher condensation efficiency.

VSMPO: Aerospace-grade Ti-6Al-4V alloy for high-pressure pump shafts.
