ABSTRACT:
A flexible tubular pipe for transporting hydrocarbons, the pipe comprising at least one carcass, an internal pressure sheath and one or more armor layers. The carcass forms the innermost structural element of the pipe and consists of an interlocked spiral winding of a strip or wire with some shape. The turns of the carcass are internally covered with an anti-turbulence sheath pierced with holes which is intended to oppose turbulence of the hydrocarbon flowing through the pipe and prevent associated resonance phenomena.
