ASTM B338 is a standard for Seamless and Welded Titanium and Titanium Alloy Tubes for Condensers and Heat Exchangers.ASTM B338 Seamless Tubes offer roughly 20% more working pressure than welded tube and are chosen over welded titanium tube when high corrosion resistance is needed.
| ASTM B388 | Grade |
| Unalloyed Titanium | Grade 1,Grade 2,Grade 3,Grade 7,Grade 11 (CP Ti-0.15Pd),Grade 16,Grade 17,Grade 26,Grade 27 |
| Titanium Based Alloys | Grade 5,Grade 9 ( Ti 3Al-2.5V),Grade 12 (Ti-0.3-Mo-0.8Ni),Grade 19 (Ti Beta C),Grade 23 (Ti 6Al-4V ELI),Grade 28 |
* ASTM B 388 Grade 1 and Grade 2 are the commonly used material in Unalloyed Titanium family,Grade 5 alloy is the most commercially available of all titanium alloys.
Size And Tolerances:
SHEW-E stock and sell ASTM A338 titanium tubing in size range outside diameter 9.53–38.1 mm (3/8–1½ in.),wall thicknesses from 0.7 to 5 mm (0.0275 to 0.1968 in.).
| OD, mm | Tolerances OD, mm | WT min wall % | Length mm |
| < 25.4 | ±0.102 | +20/-0 | 4000-9000 |
| 25.4-38.1 | ±0.127 | +20/-0 | 4000-15000 |
* Tolerances for OD < 15.9 or > 38.1 - or closer tolerances - after special agreement.
* The titanium tubes are delivered in straight lengths or as U-bent tubes.
Application:
Titanium tubing is primarily used in aerospace applications, since it does not have the strength for most hydraulic applications. It’s also widely used in power generation, chemical processing and medical applications.
