A toroidal pressure vessel comprises two annular, complementarily formed axial sections which are intersecured along a duality of annular joint lines 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.

A method of manufacturing a toroidal pressure vessel comprising the steps of: (a) providing a first annular member configured to define a semi-torodial portion of a hollow toroidal body and having axially offset radially inner and outer annular edge portions and a radially inner wall thickness greater than its radially outer wall thickness; (b) providing a second annular member configured to define the balance of said toroidal body and having axially offset radially inner and outer annular edge portions and a radially inner wall thickness greater than its radially outer wall thickness; (c) providing complementary axially and radiallay extending engagement surfaces on at least one of the radially inner and radially outer annular edge portions of said first annular member and on at least the corresponding one of the radially inner and radially outer annular edge portions of said second annular member; (d) engaging said complementary engagement surfaces with one another to dispose said first annular member and said second annular member in a singular selected relative axial and radial position; and (e) forming said toroidal body by respectively sealingly intersecuring said inner edge portions and said outer edge portions of said first and second annular members.
