摘要 |
<p>The invention concerns an unbonded flexible pipe with a length and a center axis along its length. The unbonded flexible pipe comprises an internal sealing sheath (2) surrounding the center axis, and at least two tensile armor layers (4, 6) comprising cross wound elements surrounding the internal sealing sheath (2). The two tensile armor layers (4, 6) comprise a first tensile armouring layer (4) comprising a plurality of first helically wound, elongate armoring elements, and a second tensile armoring layer (6) comprising a plurality of second helically wound, elongate armoring elements. The first helically wound, elongate armoring elements consist of a first material or a first combination of materials and the second helically wound, elongate armoring elements consist of a second material or a second combination of materials, where the first material or the first combination of materials is different from the second material or the second combination of materials. The unbonded flexible pipe further comprises a galvanic barrier (5) between the first and the second tensile armoring layer (4, 6).</p> |
