4. Mechanical & Corrosion Performance
-
Tensile Strength: Annealed ≥895 MPa; Cold‑worked condition can reach higher strength level
-
Yield Strength: Annealed ≥828 MPa
-
Elongation: Annealed ≥10%
-
Corrosion Resistance: Good resistance for seawater, chloride brine and weak acid medium; not suitable for strong reducing acid environment without palladium modification.
-
Processing Feature: High strength‑to‑weight ratio; argon‑shield welding required; cold‑worked version for higher pressure bearing requirement.
5. Full Size Range
-
Outer Diameter: Custom range from small bore to heavy‑wall dimension per drawing
-
Wall Thickness: Standard SCH series or custom non‑standard wall thickness
-
Length: Random length, fixed cut‑length or customized maximum length
-
Custom options: Special tolerance, inner‑hole finishing, end‑face preparation for welding connection.
6. Surface Treatment Options
-
Pickled surface: Remove oxide after heat treatment, standard industrial delivery finish.
-
Inner & outer polished surface: For heat‑exchanger tube, reduce medium sediment accumulation.
-
Machined end face: Deburred tube ends for convenient on‑site welding assembly.

Gr5 Ti‑6Al‑4V Seamless Tube
|
Gr2 Pure titanium seamless tube
|
|
Mechanical Strength
|
Very high, suitable for high‑pressure load
|
Medium strength, for general corrosion service
|
|
Ductility
|
Limited, not fit for heavy forming
|
Excellent, good bending performance
|
|
Chloride corrosion resistance
|
Good
|
Excellent
|
|
Typical working scenario
|
High‑pressure structural tubing
|
Chemical low‑medium pressure heat‑exchange loop
|
Choose Ti‑6Al‑4V seamless tube when projects require both corrosion resistance and high mechanical strength under pressure working condition.
8. Strict Quality Control & Test Items
-
Raw titanium billet incoming chemical and surface inspection.
-
Cold‑drawn process monitoring, intermediate annealing parameter record.
-
Full dimension inspection: Outer diameter, inner diameter, wall‑thickness and length measurement.
-
NDT test: Eddy‑current inspection for surface defect; hydrostatic pressure test for pressure‑bearing tubing; UT optional for heavy wall tube.
-
Surface visual inspection for scratch, crack and contamination.
-
Issued documents: EN10204 3.1 MTC, hydro‑test report, NDT inspection record, batch traceability file.
9. Export Packaging & Shipment
-
Inner packing: Anti‑rust plastic cap for tube ends, anti‑rust film wrapping to avoid dust and moisture.
-
Outer packing: Fumigated export wooden crate, separate spacer to prevent tube collision and scratch.
-
Marking: Print grade, standard, dimension, heat number on each tube bundle.
-
Trade terms: FOB, CIF, DDP available; sea freight for bulk tubes, air freight for small‑bore urgent orders.
