<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 into a continuous substantially 720 degree wrap to form a generally cylindrical vessel body having possible multiple fluid passageways, at the election of the user. The primary seam ( 250 ) is concealed.</p> |
