Titanium Pipe vs Titanium Tube

"Pipe" and "tube" are often used loosely, but in titanium procurement they mean different things and follow different standards.

Titanium Pipe

• Sized by Nominal Pipe Size (NPS) and schedule (wall)
• Built for fluid/gas transport and pressure
• Standards: ASTM B337 / B861 (seamless) / B862 (welded)

Titanium Tube

• Sized by exact outside diameter and wall thickness
• Tighter dimensional tolerances
• Used for heat exchangers, instrumentation, structures
• Standard: ASTM B338

How to Choose

If you're moving fluid through a piping system, order pipe by NPS and schedule. If you need precise OD/wall for a heat exchanger or mechanical part, order tube.

Materials

Both are commonly Grade 2 for corrosion service, with Grade 7/9/12 for higher demands.
