Fleksibel ledning til transport af fluider

摘要

An improved flexible flowline (1) for conveying fluids. From the inside to the outside, the inventive flowline comprises the following: a spirally wound flexible metal frame (2) with non-connecting coils (3), a compressible rod (10) disposed in the gap (9) between the consecutive coils of the spiral winding, an inner extruded impervious sheath (4) on said metal frame, at least one layer of armouring that is wrapped around the inner impervious sheath (4) and at least one outer impervious sheath (8) disposed around the sheet of armouring. The invention is characterised in that the compressible rod (10) has a high volumetric deformation of at least 50 % when compressed.
