Toroidal pressure vessel and associated manufacturing methods.

摘要

A toroidal pressure vessel (10) comprising two annular, complementarily formed axial portions (26, 28) which are secured together along two annular joint lines (64, 66) that circumscribe and are mutually offset along the axis of the toroid. The axial sections are formed by machining a pair of end portions removed from a length of thick-walled metal tubing.
