Meta Description: Titanium sheet for seawater desalination project from Baoji ready stock. Gr2/TA2 ASTM B265, 0.5–50mm, evaporator/plate-heat-exchanger stock, cut-to-size, MTC EN 10204 3.1, same-day dispatch on confirmed in-stock orders. Quote within 24h.

Overview

Seawater desalination is one of the harshest service environments for any metal: high chloride concentration, dissolved oxygen, biofouling, fluctuating velocity, and high-temperature brine in distillation routes. We are a Baoji-based titanium inventory holder with 800 tons total titanium stock, including ~400 tons of Titanium Plate/sheet. For desalination EPC teams, OEMs, and HX fabricators, we supply Gr2 (TA2) titanium sheet from ready stock — annealed, pickled or bright-finished, cut to drawing, with full heat-number traceability. This page explains grade choice, thickness routing by equipment type, stock reality, fabrication notes, and how to enquire without a wasted email round-trip.

Why Titanium, Why Gr2/TA2 for Desalination

Titanium forms a self-healing TiO₂ passive film. In seawater it does not rely on a thick corrosion allowance — the oxide reforms instantly if scratched.

• Chloride immunity: no pitting/crevice failure like 316L or even 6Mo in stagnant chloride zones (when velocity/design reviewed)
• Biofouling-friendly: smooth pickled/bright surface slows scale adhesion; cleanable by mechanical/chemical wash
• Lightweight: density 4.51 g/cm³, ~45% lighter than steel — lowers skid, shell, and support cost
• Weldable: GTAW/TIG with argon backing; compatible with Gr2 tube, tube sheet, and shell liner
• Life-cycle cost: lower than duplex over 15–25-year design life when replacement/downtime is counted

Note: pure titanium is not for hydrofluoric acid, dry chlorine at high temperature, or strong reducing acid without grade review. We confirm medium data before substituting Gr7/Gr12.

Desalination Routes & Where Sheet Goes

Stock Snapshot (Honest, Rotating)

Standard mother size 1000×2000 / 1219×2438 / 1500×3000mm. Cut-to-size from stock; live count confirmed before PI.

Technical Parameters (Gr2 / TA2)

Thickness Selection Guide (Engineering Logic)

• 0.5–2mm: PHE stamped plates, corrugated cassettes, light cladding — formability first
• 2–4mm: MED effect walls, RO brine cooler shells, demister frames — balance of form + pressure
• 4–8mm: MSF flash chambers, baffle/structural liner — erosion margin for brine velocity
• 10–30mm: tube sheets, thick shell flange backup, pressure-part liner

Rule of thumb we give clients: plate-heat-exchanger ≈ 2mm BA; shell-and-tube liner ≈ 3mm pickled; tube sheet moves to thick plate. Final wall must come from the project stress sheet — we supply material, not the design stamp.

Cutting & Fabrication Support

Every cut piece keeps its heat-number tag. We never mix grades on the cutting bed.

Surface Finish — Which One for Desalination

Export Packaging for Desalination Sheets

• PE interleave film between every sheet
• Kraft paper + foam edge guards on cut blanks
• Plywood dividers inside fumigated wooden crate (ISPM-15)
• Moisture-barrier bag + desiccant for long-sea (Middle East/Africa/South America)
• Flat steel frame for ≤2mm sheet to kill transit bend
• Marking: grade, heat No., thickness, dims, PO ref etched/tagged per piece

Quality Before Dispatch

• Thickness micrometer at 4 corners + center
• Flatness ≤3mm/m after leveling
• UT for ≥20mm plate
• Heat-number ↔ MTC EN 10204 3.1 cross-check
• XRF/PMI grade verification on request
• No substitution without written confirmation
• SGS / BV / TUV third-party at buyer cost

Grade Upgrade Path (Only When Medium Demands)

We do not auto-upgrade to inflate price. Send chloride ppm, temperature, pH, velocity, and whether dry chlorine/hydrofluoric acid exists — we reply with the grade reason.

FAQ — Desalination Titanium Sheet

Q1: Is Gr2 enough for seawater, or do I need Gr7?
A: For open seawater, normal chloride, wet chlorine — Gr2 is the industry default. Gr7 is for reducing-acid/high-temp acid duty, not routine seawater.

Q2: What thickness for a plate-heat-exchanger cassette?
A: Most projects use 0.6–2mm bright-annealed Gr2/Gr1. Final wall from pressure/velocity design; we supply the sheet, you (or your ASME shop) own the stamp.

Q3: Can you supply coil for automatic stamping lines?
A: Yes — slit coil 0.5–2mm, PE interleaved, inner Ø505/610mm, on request.

Q4: How do you avoid iron contamination in cutting?
A: Dedicated titanium cutting line, cleaned fixtures, no carbon-steel contact, pickling passivation available post-cut.

Q5: Will thin sheet bend in a 40-day sea voyage?
A: Not with our pack — flat steel frame + moisture barrier + foam edges. We ship 0.5mm to GCC/Africa with zero flatness claims using this method.

Q6: Can you roll sheet into shell liner?
A: Yes via partner rolling shop — send developed length + radius; we supply cut blank, then roll, then mark heat number on the seam edge.

Q7: Do you support EPC documentation packs?
A: MTC 3.1, PMI report, dimensional inspection record, COO, packing list — full dossier for vendor doc control.

Q8: Lead time?
A: In-stock thickness + cut: same day if confirmed before 3 PM China time. Rolling/welding prep adds 2–5 working days.

Q9: Can Gr2 handle brine concentration in MSF last stage?
A: Yes for chloride service within normal desalination design; velocity and deposit control matter more than grade. We advise, but the process engineer sets limits.

Q10: Sample before bulk?
A: 100×100mm coupon from same heat, DHL/FedEx at cost, deductible from PO.
