Manufacture of Welded tubes



Round longitudinal welded tubes are produced from flat rolled material (strip) on the tube-welding lines by automatic TIG welding with heat treatment in the line.

VSMPO delivers tubes with the diameters of 12.7 - 38.1 mm (0.5"-1.5"), with the wall thickness of 0.5 - 1.65 mm (0.02"- 0.06") and with the length of up to 25000 mm from Gr1 and Gr2 titanium alloys for application in power engineering and chemical industry.

Finished welded tubes are subject to laser inspection of diameter, geometry measurements, 100% UST and eddy-current inspection, pneumatic and hydraulic tests. The tubes are packed in accordance with customer specifications.

Production process and appropriate inspection techniques allow to produce thin-walled welded tubes against ASTM B 338 and ASME SB 338 specifications.
