<p>A multilayered pressure vessel (10) fabricated from at least one single ply sheet of flexible material (100) having an approximate longitudinal midline which divides the material into an inner portion (130) having an inner surface, an outer surface, an edge, a seam allowance, and a width, and an outer portion having an inner surface, an outer surface, an edge, a seam allowance, and a width. The width of the outer portion (120) is greater than the width of the inner portion (140). A primary seam (250) binds the outer portion and the inner portion to the material sheet at the midline proximate the outer portion edge and inner portion edge. The sheet (100) is wrapped in to a continuous substantially 720 degree wrap to form a generally cylindrical vessel body having possible multiple fluid passageways, at the election of t he user. The primary seam (250) is concealed.</p> |
