ASTM B338 Titanium tube

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.




Unalloyed Titanium

Grade 1,Grade 2,Grade 3,Grade 7,Grade 11 (CP Ti-0.15Pd),Grade 16,Grade 17,Grade 26,Grade 27

* 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. 


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.
