Abstract

A toroidal shaped container including a body made from tubing and formed into a ring is disclosed. The tube is bent so that the tube ends are aligned and spaced apart a distance with a closure piece inserted between the aligned ends and welded thereto to form a closed container. In a preferred embodiment the closure piece includes a boss projecting radially from the closure piece with an inwardly extending threaded aperture formed in the boss penetrating the interior of the pressure vessel.
