Seamless, welded, coiled and square titanium tubing — engineered for shell-and-tube heat exchangers, process piping and systems that demand corrosion resistance combined with low structural weight.
Eight tube and pipe types covering industrial process, heat exchanger and structural needs.
Pierced and cold-drawn tubing — preferred for high-pressure and heat-exchanger duty.
Rolled-and-welded tubing for larger diameters and structural or low-pressure uses.
Bent or coil-form titanium tubing for heat exchangers, chillers and condensers.
Square or rectangular titanium tubing for structural fabrication and frames.
Fine diameter precision-drawn titanium capillary tubing for analytical, instrumentation and specialty process equipment.
Flat or oval profile titanium tubes for compact heat exchanger and radiator applications.
Corrugated or rifled titanium tubes for enhanced heat transfer in heat exchangers.
Specialized titanium tubing for shell-and-tube and plate heat exchanger assemblies.
Titanium tubes and pipes are produced by two principal manufacturing routes: seamless (pierced and cold-drawn from solid billet) and welded (formed from strip or sheet and longitudinally welded). Feinuotai supplies seamless titanium tubes, welded titanium tubes, and coiled titanium tubing in Grade 1, 2, 3, 4 (commercially pure titanium), Grade 5 (Ti-6Al-4V), Grade 7, 9 and 12. Seamless tubing is typically preferred for high-pressure and critical-duty applications where material continuity matters, while welded tubing can offer cost advantages for larger diameters and structural uses. Coiled tubing — formed from straight lengths — is used in chillers and compact heat-exchanger designs. Grade 1, 2 and 5 are available from stock. Grade 3, 4, 7, 9 and 12 are available on a per-inquiry basis.
Titanium tubing resists pitting and crevice corrosion from seawater, acids and chloride-containing media far better than carbon steel or most stainless alternatives — the reason it has become standard for shell-and-tube heat exchangers, condensers and process piping in chemical, desalination, marine and power-generation plants. Coiled tubing, formed from straight lengths, is widely used in chillers and compact heat-exchanger designs.
Titanium tube and pipe from Feinuotai is produced to ASTM B338 (heat exchanger and condenser tubing), ASTM B337 (seamless and welded pipe), and applicable ASME B31.3 process piping codes. All grades and diameter ranges are covered.
Feinuotai supplies tubing in eight product configurations — each with its own production route and downstream application.
| Product | Manufacturing Method | Key Application |
|---|---|---|
| Seamless Tube / Pipe | Pierced billet → cold drawn → annealed | High-pressure, high-availability process piping and heat exchangers |
| Welded Tube / Pipe | Rolled strip → longitudinally welded → annealed | Large-diameter structural and low-pressure process lines |
| Coiled Tube | Straight tube bent to coil form | Shell-and-tube heat exchangers, chillers and condensers |
| Square / Rectangular Tube | Cold formed from flat strip or drawn from round | Structural fabrication, frames and supports |
| Capillary Tube | Precision drawn to fine diameters | Analytical, instrumentation and specialty process equipment |
| Flat / Oval Tube | Rolled or drawn to non-circular profile | Compact heat exchanger and radiator assemblies |
| Corrugated / Rifled Tube | Surface-enhanced for turbulence | Enhanced heat-transfer shell-and-tube exchangers |
| Heat Exchanger Tube | Standard and special lengths per exchanger design | Shell-and-tube and plate heat exchanger assemblies |
Feinuotai supplies a broad OD and wall thickness range across six standard titanium grades. Seamless and welded routes both available — the selection depends on diameter, pressure class and availability.
| Dimension | Standard Range |
|---|---|
| Outside Diameter (OD) | 3.0 mm – 300 mm (0.118" – 11.8") |
| Wall Thickness (WT) | 0.2 mm – 15 mm |
| Length | 1,000 mm – 6,000 mm (standard); custom lengths on inquiry |
| End Preparation | Square end, beveled, belled per specification |
| Grade | Alloy | Common Uses |
|---|---|---|
| Grade 1 | CP | Low-pressure, corrosion-resistant applications |
| Grade 2 | CP | Most widely used — general process piping |
| Grade 5 | Ti-6Al-4V | Higher strength-to-weight, structural tubing |
| Grade 7 | Ti-0.2Pd | Palladium-stabilized, extreme chemical corrosion |
| Grade 9 | Ti-3Al-2.5V | Lower-cost alloy for aircraft and hydraulic tubing |
| Grade 23 | Ti-6Al-4V ELI | Medical and high-reliability applications |
Feinuotai provides bent and formed titanium tubing as a standard service — not a separate specialty. Common bend configurations include 90° and 45° bends, U-bends, coil bends, offset bends and custom drawings.
Hydraulic and rotary draw bending to R = 1.5D and beyond — standard for 90° and 45° elbows in all grades.
U-bends, J-bends, offset bends, multiple-plane bends — produced to customer supplied drawings.
Complete tube assemblies produced to DWG / STEP / DXF drawings — including bending, cutting, beveling and end preparation.
Heat exchangers, condenser coils, offshore riser bends, chemical process loop lines and instrument tubing — all available pre-bent.
Standard tube lengths, grades and diameters ship from stock. Non-standard tubing, bent forms and drawing-based assemblies are coordinated per inquiry. For drawing-based or custom requirements, you may share your drawings with our sales team by email or WhatsApp after initial contact.
Shell-and-tube and plate heat exchangers in chemical, marine and desalination plants.
Piping for acids, brines and other corrosive fluids where carbon steel fails.
Evaporators, condensers and auxiliary systems exposed to seawater.
Corrosion-resistant risers, umbilicals and auxiliary tubing.
Seamless tubing is typically preferred for high-pressure and critical-duty applications where material continuity matters. Welded tubing can offer cost advantages for larger diameters and structural uses. The supply route is confirmed per inquiry.
Seamless, welded and coiled tubing are supplied in Grade 1, 2, 3, 4 (commercially pure titanium), Grade 5 (Ti-6Al-4V), Grade 7, 9 and 12. Grade 1, 2 and 5 are available from stock; Grade 3, 4, 7, 9 and 12 are available on a per-inquiry basis.
Please state the outside diameter, wall thickness, grade, length and whether you need seamless, welded or coiled tubing — the appropriate supply route and lead time are then confirmed.
Seamless tube is produced by piercing a solid billet and drawing to final diameter — preferred for high-pressure, high-availability and corrosion-critical applications. Welded tube is produced by rolling flat strip and longitudinally welding — more economical for large-diameter, structural or low-pressure uses.
Yes — titanium tube bending is a standard Feinuotai supply service. We can produce 90°, 45°, U-bends, J-bends, offset bends and custom configurations to your drawings. Confirm bend angle, bend radius (R = 1.5D minimum) and quantity in your inquiry.
ASTM B338 specifies diameter tolerance of ±0.25% (plus ovality) and wall thickness tolerance of ±10% for seamless tube and ±12.5% for welded. Tighter tolerances available on inquiry.
For drawing-based or custom titanium tube requirements (including bending), you may share your drawings with our sales team by email or WhatsApp after initial contact. Include grade, OD, wall thickness, length/quantity and applicable standard.
