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.
