Titanium tubing

Tube, pipe, fittings and flanges

Titanium tubing tubing suitable for environments and applications where the properties of stainless steels are not sufficient.

Typical applications include tubing for the aerospace industry and heat-exchangers.

Our titanium tubing is available in size range outside diameter 9.53–38.1 mm (3/8–1½ in.) with wall thicknesses from 0.7 to 5 mm (0.0275 to 0.1968 in.). The titanium tubes tubes are delivered in straight lengths or as U-bent tubes.

Sizes and tolerances for titanium tubes

Sandvik titanium tubes are available in size range outside diameter 9.53-38.1 mm (3/8 - 1 1/2 in.) with wall thicknesses from 0.7 to 5 mm (0.0275 to 0.1968 in.)^*.

OD = outside diameter
WT = wall thickness

Size OD, mm (in.)	Tolerances OD, mm (in.)	WT min wall %
< 25.4 (< 3/8)	±0.102 (0.004)	+20/-0
25.4-38.1 (1-1 1/2)	±0.127 (0.005)	+20/-0

Tolerances for OD < 15.9 or > 38.1 - or closer tolerances - after special agreement.

*Limitations for some ratios of OD/WT exist
