A multi-bed PSA pressure vessel includes a hollow tubular body having one or more end plates releasably secured thereto. Secured to the end plate(s) are pipes which extend along the interior of the hollow tubular body. Each of the pipes terminates at a location along the length of the tubular body different from the remaining pipes. In a preferred embodiment, a plurality of perforated spacing flanges are secured to the pipe and some adjacent flanges defining between them a space for receiving adsorbing sieve material.
