Polished titanium tube bundle with end-caps - ASTM B338

Titanium Tubing

Key Advantages

Seamless or welded tubing for precision flow and structural use.
High strength-to-weight ratio and corrosion resistance in chloride and process media.
Tight OD/WT tolerances; straightness and ovality controlled for automated assembly.
Clean, pickled/polished surfaces; internal cleanliness for fluid systems.
Traceable production with in-house inspection and MTC EN 10204 3.1.

Primary Applications

Chemical processing: heat-exchangers, condensers, corrosive-media lines.
Aerospace: hydraulic and pneumatic lines, lightweight structures.
Medical/biotech: instrumentation housings, non-implant fluid circuits.
Marine: desalination, offshore process tubing.

Testing

Dimensional checks: OD, wall thickness, ovality, straightness, length.
NDT: ultrasonic/eddy-current (per size and spec).
Hydrostatic/air-under-water pressure testing (on request).
Chemistry verification (O, N, H, Fe, etc.).
Mechanical sampling (tensile/yield/elongation) per heat-size.

Packaging & Delivery

End-caps and internal protection; bundles in export plywood cases.
Labels: grade, OD x WT, length, condition, heat/lot, PO.
Global courier or sea freight; lead times aligned to your schedule.

Send your specifications (grade, size, quantity) — quotation and lead time within 12 hours. Trial orders with flexible MOQ are supported for evaluation and qualification. All materials are supplied with EN 10204 3.1 MTC and full inspection documentation for export compliance.

Product Description

Exported to USA, EU and Middle East markets with full inspection reports.

Premium titanium tubing for chemical systems, aerospace lines and high-reliability assemblies. LuminaTitan supplies seamless and welded tubing produced under controlled processes and verified in-house to deliver low mass, corrosion resistance and consistent mechanical behavior.

Technical Specifications

Parameter	Details	Why It Works for You
Standards	ASTM B338 (tubes), ASTM B337 (pipes); AMS 4943/4944 (where applicable)	Aligns with common buyer specs for procurement and QA.
Grades	Gr1, Gr2, Gr3, Gr5 (Ti-6Al-4V), Gr7, Gr9, Gr12, Gr23 (ELI)	Balances corrosion resistance and strength across applications.
Forms	Seamless / welded; straight lengths or coiled (small OD)	Matches pressure/flow and routing needs.
Dimensions	OD 3.0-114.3 mm; wall 0.2-6.0 mm; length up to 6 m (typical)	Covers micro lines to structural tubes; long lengths reduce joints.
