A small tank or vessel for the containment of pressurized fluids is formed by joining the outer edges of the arms of integral upright and inverted double-Y sections arranged side by side. The arms are part cylinders terminating in the vertical centerline of a cylinder so that a septum between adjacent cylindrical lobes is formed by the vertical legs of the double-Y. A semi-cylindrical shell may be attached to the outer arms of each outside double-Y form.
