Pierced and cold-drawn from solid titanium billet -- no longitudinal weld seam. Preferred for high-pressure, high-availability and corrosion-critical duty.
Supply ranges are presented in three tiers to distinguish industry reference, custom coordination and regular stock availability.
| Parameter | Standard / Industry Reference Range | Custom Supply Range | Regular Stock Range |
|---|---|---|---|
| Outer Diameter (OD) | 10 – 273 mm | To Be Confirmed Against Product Requirements | Common sizes within the 10 – 273 mm range |
| Wall Thickness | Default Sch 40 reference | Final wall thickness confirmed against OD, specification and order requirements | Sch 40 for common OD sizes |
| Length | 2 – 6 m standard production length | Cut lengths and fixed lengths per order | 2 – 6 m random lengths |
| End Preparation | Square cut, plain ends standard | Beveled ends, threaded ends, flanged ends per drawing | Square cut plain ends |
Grade availability is tied to manufacturing route, OD and wall thickness. Not every grade can be produced in every size.
Grade 1 (CP Ti), Grade 2 (CP Ti), partial Grade 5 (Ti-6Al-4V). Available in common diameters from mill stock.
Grade 3, Grade 4, Grade 7 (Ti-0.15Pd), Grade 9 (Ti-3Al-2.5V), Grade 12 (Ti-0.3Mo-0.8Ni), Grade 23 (Ti-6Al-4V ELI). Supply feasibility reviewed per order against tube diameter, wall thickness and forming route.
Some titanium plate grades (Grade 16, Grade 17 and others) are not standard seamless tube production grades. Availability for specific projects requires technical review. Not every plate grade transfers directly to tube form.
Standards listed below are provided as industry references. Final standard selection must match the actual product form, material grade and order specification.
ASTM B338 / B338M — Standard Specification for Seamless and Welded Titanium and Titanium Alloy Tubes for Condensers and Heat Exchangers. Applies specifically to round titanium tubes intended for heat exchanger and condenser service. Seamless route covered.
ASTM B337 / B337M — Standard Specification for Seamless and Welded Titanium and Titanium Alloy Pipe. Applies to round titanium pipe for general process piping and pressure service.
Applicability of these standards to a specific order depends on tube OD, wall thickness, grade and intended service. Square, rectangular, flat, corrugated, capillary or enhanced-surface titanium tubes are not directly covered by B338/B337 and should be evaluated against the applicable product requirement or agreed specification.
Solid titanium billet of the required grade is inspected, machined to diameter and heated.
The heated billet is pierced on a rotary piercing mill to create a hollow shell.
The pierced shell is hot-rolled to reduce diameter and wall thickness.
Cold drawing through precision dies achieves final OD, wall thickness and surface finish.
Annealing, straightening, end facing, nondestructive inspection and length cutting per order.
Seamless titanium tubes are selected where pressure containment, material continuity and corrosion resistance under demanding conditions are the primary requirements.
Titanium tube bundles for corrosive process fluids, seawater, brackish water and chemical heat exchanger service. Grade 2 is the most common grade for this application.
Corrosive media transfer lines in chemical processing, pharmaceutical and specialty chemical plants. Seamless construction is preferred for pressure-class systems where no weld seam is permitted.
Titanium condenser tubing and auxiliary piping in MED desalination plants, surface condensers and flue-gas desulfurization systems.
Titanium hydraulic tubing in marine and subsea systems, where corrosion resistance and high-pressure capability are both required.
Available documentation is coordinated against the order specification and applicable requirements.
Grade 1 (commercially pure titanium), Grade 2 and partial Grade 5 (Ti-6Al-4V) seamless tubes are available from mill stock in common diameters within the 10 – 273 mm OD range. Other grades including Grade 3, Grade 4, Grade 7, Grade 9 and Grade 12 are produced to order and their feasibility depends on the specific OD, wall thickness and forming route.
Sch 40 is a nominal wall thickness schedule reference used in pipe and tube standards. For a given outer diameter, Sch 40 defines a nominal wall thickness value. It is provided here as a default reference only. Final wall thickness for a specific order must be confirmed against the actual OD, the product specification and the order requirements. Not every size in the 10 – 273 mm OD range is produced with Sch 40 wall as standard stock.
Seamless tube is produced by piercing a solid titanium billet and cold-drawing the pierced shell to final diameter. There is no longitudinal weld seam. Seamless tubes are preferred for high-pressure, high-availability and corrosion-critical applications. Welded tubes are produced by rolling titanium strip into tubular form and longitudinally welding the seam. Welded tubes can cover larger diameters and are generally more economical for structural or lower-pressure uses.
The confirmed outer diameter range for seamless titanium tubes is 10 – 273 mm. Not every diameter within this range is stocked as regular stock. Common sizes are available from mill inventory, while non-standard diameters within the range can be coordinated as custom production.
Yes. Seamless titanium tubes can be bent, flanged, threaded, grooved or fitted with pipe fittings depending on the grade, OD, wall thickness and required operation. Feasibility and minimum bend radius should be confirmed per inquiry. Titanium welding and tube forming can be coordinated for downstream fabrication.
