Manufacturing Process
ASTM B338 Grade 2 Titanium Seamless Tubes shall be made from hollow billet by any cold reducing or cold drawing process that will yield a product meeting the requirements prescribed.
The welded tube shall be made from flat-rolled product by an automatic arc-welding process. The welded tube shall be sufficiently cold worked to final size in order to transform the cast weld microstructure into a typical equiaxed microstructure in the weld upon subsequent heat treatment.
NDT/Ultrasonic Test
The welded tube shall be subjected to a reverse flattening test in accordance with supplement II of test methods and definitions A 370. Welded tubing shall be tested using both NDT test and the ultrasonic test method.
Seamless and welded/cold-worked tubing shall be tested using an ultrasonic test method.
Hydrostatic Test
Welded tubing shall be tested with a hydrostatic or pneumatic test method.
ASTM B338 Grade 2 Titanium Seamless Tubes shall be tested with an electromagnetic or hydrostatic or pneumatic test method.
