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.
