초록 ▼

In a flexible line pipe comprising an inner corrugated metal tube (4), an outer corrugated metal tube (5) located at some distance from the inner tube (4) and a spacer as well as an insulation material between the inner and the outer metal tubes, whereby a pressure that is less than atmospheric pressure prevails in the ring-shaped gap (6) between the tubes, the spacer comprises two cords (7, 8) made of fiber-reinforced plastic applied to the inner tube (4) and wrapped in opposite directions. The insulation material (9) is a fleece material, and the pressure in the ring-shaped gap is between 10.sup.-3 and 10.sup.-1 mbar.
