<p>The pipeline has an inner tube (1) and an outer tube (2) that are coaxial to each other for maintaining a space between them by using a spacer unit. The tube (2) has inner and outer layers (7, 9), where the layer (7) is helically corrugated and is free with respect to the tube (1) for forming the spacer unit. The layer (7) has an inner diameter that is greater than the outer diameter of the tube (1). The tube (2) has an intermediate layer (8) formed of a band surrounding the layer (7). The tube (1) has an inner layer (3), an intermediate layer (4), a tubular frame (5) and an outer layer (6). An independent claim is also included for a method of manufacturing a fuel transport pipeline.</p> |
