More Information
Summary:The invention relates to a pipe for conveying a petroleum effluent comprising water and at least one of the acidic compounds carbon dioxide CO2 and hydrogen sulphide H2S, the pipe comprising at least one mechanical reinforcement metal part (3, 5) and a polymeric tubular pressure sheath (2), the metal part (3, 5) being arranged outside the pressure sheath (2), a diffusion barrier (B) being arranged between the pressure sheath (2) and the mechanical reinforcement metal part (3, 5). According to the invention, the barrier (B) comprises at least one metal strip (F) wound around the sheath (2) so as to provide a metal covering of between 35 and 75% intercalated with a polymeric material (P).
