ASTM B861 Gr.2 seamless titanium tube is a commercially pure titanium product, not an alloy steel tube. It is selected for heat-exchanger systems where seawater, chlorides, wet chlorine compounds, and many oxidizing media create high corrosion risk. ASTM B861 covers seamless titanium and titanium alloy pipe for general corrosion-resisting and elevated-temperature service, while ASTM B338 is the closer tube standard for condensers, evaporators, and heat exchangers.
| Item | Description |
|---|---|
| Material | Commercially pure titanium / titanium alloy |
| Main Grade | ASTM B861 Grade 2 / UNS R50400 |
| Optional Grades | Gr.1, Gr.7, Gr.9, Gr.12 |
| Outside Diameter | 5-168 mm |
| Wall Thickness | 0.2-5.2 mm |
| Length | 1-12 m standard, up to 15 m max, custom cut length available |
| Tolerance Range | OD and WT according to ASTM B861 / ASTM B338 or agreed drawing tolerance |
| Straightness | Typically ≤1.5 mm/m for heat-exchanger tube supply, tighter by agreement |
| Surface Condition | Pickled, polished, bright annealed, or mechanically polished |
| Heat Treatment | Annealed; Grade 9 may be supplied annealed or cold-worked and stress-relieved according to order condition |
| Manufacturing Method | Seamless cold drawn / cold rolled from hollow billet |
| Inspection | Chemical analysis, tensile test, hydrostatic or pneumatic test, dimensional inspection, visual inspection |
| Property | Practical Value for Procurement |
|---|---|
| Corrosion Resistance | Grade 2 titanium provides strong resistance in seawater and chloride-containing cooling water, making it suitable for condenser and heat-exchanger tube bundles. |
| Strength Level | ASTM Gr.2 minimum tensile strength ≥345 MPa, yield strength 275-450 MPa, elongation ≥20%. |
| Low Density | Density about 4.51 g/cm³, roughly 56% of common stainless steel density, helping reduce tube-bundle weight. |
| Heat-Exchanger Suitability | ASTM B338 specifically covers titanium tubes for surface condensers, evaporators, and heat exchangers. |
| Surface Finish | Polished or pickled surface reduces fouling tendency and supports easier cleaning in heat-transfer service. |
| Weldability | Commercially pure Grade 2 titanium has good weldability when shielding gas and contamination control are properly managed. |
| Professional Concern | How We Address It |
|---|---|
| Wrong standard selection between pipe and tube | For "ASTM B861 Gr.2" inquiries, we clarify whether the buyer needs seamless pipe under ASTM B861 or heat-exchanger tube under ASTM B338, because ASTM B338 is written for condensers, evaporators, and heat exchangers. |
| Risk of leakage in tube sheets | We control OD tolerance, straightness, surface finish, and end-cut quality to improve tube insertion, expansion, and sealing performance. Hydrostatic or pneumatic testing can be arranged before shipment. |
| Grade mismatch in corrosive media | We help match Gr.2, Gr.7, Gr.9, or Gr.12 according to chloride level, strength requirement, and corrosion severity. Grade 7 adds palladium, Grade 9 adds Al-V for higher strength, and Grade 12 adds Mo-Ni for improved corrosion resistance. |
