发明名称 AN UNBONDED FLEXIBLE PIPE
摘要 <p>An unbonded flexible pipe with a length and a center axis along its length includes an internal sealing sheath surrounding the center axis, and at least two tensile armor layers having cross wound elements surrounding the internal sealing sheath. The two tensile armor layers include a first tensile armoring layer having a plurality of first helically wound, elongate armoring elements, and a second tensile armoring layer having 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 includes a galvanic barrier layer between the first and the second tensile armoring layer.</p>
