Abstract
The present techniques are directed to a flexible pipe. An inner carcass layer forms the innermost layer of the flexible pipe. An inner sheath layer and an outer sheath layer are disposed externally of the inner carcass layer. A layer of corrosion resistant alloy is disposed at any location between the inner carcass layer and the outer sheath layer. At least one armor layer is disposed internally of the outer sheath layer.
Claims14
A flexible pipe, comprising
- an inner carcass layer;
- an inner sheath layer and an outer sheath layer each disposed externally of the inner carcass layer and each comprising a polymer material;
- a layer of corrosion resistant alloy, wherein the corrosion resistant alloy layer is disposed at any location between the inner carcass layer and the outer sheath layer, and further wherein the corrosion resistant alloy layer is solid and provides a non-permeable layer such that diffusion of corrosive fluids, water, or both are inhibited;
- and
- at least one armor layer disposed internally of the outer sheath layer.
