摘要: A pressure vessel may be formed from a thermally processed metal tube. The thermally processed metal tube may be seamless with a large length to diameter ratio. End portions of the thermally processed metal tube may be formed at a first temperature below the lower critical temperature by a load less than about the ultimate stress of the metal. After forming, the end portion may be thermally reconditioned at a second temperature below the lower critical temperature to relieve stress and approach similar material properties as the thermally processed metal tube.
