Sandvik Materials Technology is a developer and producer of advanced stainless steels, special alloys, titanium and other high-performance materials

Titanium tubing and zirconium tubing

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

Sandvik titanium tubing and zirconium tubing are 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 and zirconium tubes are delivered in straight lengths or as U-bent tubes.

We also supply zirconium complementary products for heat exchanger applications.

The Sandvik program of zirconium alloy tubing also covers nuclear fuel tubes, which is one of many products in our extensive offer for applications within the area of nuclear power generation.

Sizes and tolerances for titanium tubes and zirconium tubes

Sandvik titanium tubes and zirconium 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
