Vessel

A pressure vessel for pressurizing a fluid therein, said vessel having a vertical central axis, said vessel comprising:

• an upper end wall and a lower end wall interconnected together by an intermediate and open casing comprised of a wall, said end walls sealing said casing, said casing having an outer surface and an inner surface, which said outer and inner surfaces define a casing cross-sectional wall thickness;
• a tubular part comprised of a wall having a peripheral outer surface and a peripheral inner surface, said tubular part received within said intermediate casing and interconnected between each of said end walls centrally of said axis, thereby defining a sealed central compartment, said outer and inner peripheral surfaces of said tubular part defining a cross-sectional thickness that is equal to that of said casing cross-sectional thickness;
• and
• a number of partition walls extending radially between the inner surface of said intermediate casing and the outer peripheral surface of the tubular part, said partition walls integrally formed with said casing and tubular part and equally spaced from each other so as to divide said sealed intermediate casing into a plurality of adjacent longitudinally extending internal compartments of equal size, wherein the end walls are formed by mutually separate and connected sealing plugs which are contained fully within each of said fluid accomodating compartments, said partition walls each having a respective and equal cross-sectional thickness, which said partitional wall cross-sectional thickness is equal to said cross-sectional thickness of said casing and tubular part, each of said partition walls having a respective pair of openings extending therethrough, one of said openings located at a bottom of said partition wall where connected to said lower end wall and the other of said openings located at a top of said partition wall where connected to said upper end wall, said partition wall openings causing each of said internal compartments to be fluidly interconnected with each other and wherein every other of said adjacent internal compartments are in fluid communication with said central compartment through a pair of radially oriented openings extending through the tubular part that forms that respective compartment, one of said radially oriented openings located at a bottom of said tubular part where connected to said lower end wall and the other of said radially oriented openings located at a top of said tubular part where connected to said upper end wall, said partition wall openings and said radial openings creating within each of said compartments an equal fluid pressure such that a radial pressure force arising inside said vessel as a result of an internal overpressure against said end walls will be axially and equally redistributed throughout said casing wall, each of said partition walls, and said wall of said tubular part, whereby said fluid pressure is radially and axially distributed in an equal manner within said vessel casing and end walls.
