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.

Product Description

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.
Condition	Annealed (M), cold worked (CW), straightened	Tune ductility, strength and forming behavior.
Surface	Pickled, polished, bright-cleaned; internal debris controlled	Supports clean assembly and low pressure loss.
Tolerances	Per ASTM or tighter by agreement (OD/WT/straightness/ovality)	Repeatable fit-up for automated lines.
Documentation	MTC EN 10204 3.1; inspection/test reports; RoHS/REACH	Supports audits and supplier approval.
