Titanium Sheet Applications in Desalination Plants – GR1 & GR2 Industrial Use Cases
Desalination plants require materials that can withstand highly corrosive seawater environments, including pumps, piping, and heat exchangers. GR1 and GR2 Titanium Sheets (ASTM B265) are ideal due to their exceptional corrosion resistance, durability, and ease of fabrication.
Using titanium sheets can significantly extend equipment lifespan, reduce maintenance costs, and prevent leaks, which are critical for reliable water production.

Why Titanium is Used in Desalination Plants?
- Corrosion Resistance: Titanium tolerates chlorides, saltwater, and high temperatures, making it perfect for seawater exposure.
- Strength and Longevity
- Offers high strength-to-weight ratio, reducing structural support costs.
- Provides long-term service life with minimal maintenance.
Fabrication Versatility :Can be cut, leveled, and welded to form heat exchanger plates, pump components, and piping systems.

Selection Guidelines for Desalination Components
| Component | Grade | Thickness | Surface Finish | Notes |
| Heat Exchangers | GR2 | 4–12mm | Pickled | CTL and leveling recommended |
| Seawater Piping | GR2 | 3–8mm | Pickled | Smooth edges prevent flow turbulence |
| Pumps & Valves | GR2 | 4–6mm | Pickled | Careful welding and assembly needed |
| Structural Supports | GR1/GR2 | 6–12mm | BA or Pickled | Depends on visibility and corrosion exposure |
