<p>The invention relates to a flexible tubular pipe for the transport of hydrocarbons, such as gaseous hydrocarbons, of the type comprising at least one carcass (2), an inner pressure sheath (3) and one or more armouring plies. Moreover, the aforementioned carcass (2), which forms the innermost element of the pipe, is formed by coiling a band iron (7) or a forming wire into stapled coils. The coils of the carcass (2) comprise through passages (20, 21, 22) which are disposed in the thickness thereof and which allow the hydrocarbon circulating in the pipe to flow into the coils of the carcass, such as to prevent eddying at the inner butt gaps (9) of the pipe and the associated resonance phenomena.</p> |
