Abstract
A flexible conduit used for transportation of hydrocarbon fluids for off-shore and on-shore oil and gas applications includes an inner pressure sheath, at least one reinforcing layer at least partially disposed around the pressure sheath, an outer protective sheath at least partially disposed around the at least one reinforcing layer, and optionally a thermally insulating layer disposed between the at least one reinforcing layer and the outer protective sheath. At least one of the inner pressure sheath, outer protective sheath, and the thermally insulating layer is manufactured using a thermoplastic blend (TPB) composition. The TPB compositions disclosed herein are useful for the formation of at least one polymer layer of the thermoplastic umbilical hoses used for transportation of hydrocarbon fluids.
