Zirconium tubes

Zirconium tubes

Tube, pipe, fittings and flanges

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

Zirconium tubing from Alleima 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.). Zirconium tubes are delivered in straight lengths or as U-bent tubes.

We also supply zirconium complementary products for heat exchanger applications.

The Alleima portfolio 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 zirconium tubes

Alleima 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
