Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An unbonded flexible pipe having a length and a center axis along said length, the unbonded flexible pipe comprising an internal sealing sheath surrounding said center axis, and at least a first and a second tensile armor layers comprising cross wound elements surrounding the internal sealing sheath, said first tensile armoring layer is closer to the internal sealing sheath than the second tensile armoring layer and comprises a first tensile armoring layer co…
