Abstract: Method for testing a pipe for carrying hydrocarbons. The pipe has at least one internal sealing sheath made of polymer material, incorporating elements of reactive compound capable of reacting with corrosive gases contained in the hydrocarbons which diffuse radially through the sheath. The reaction forms a first layer, extending radially from the internal surface, in which the elements of reactive compound have reacted with the gases. A second layer, extends between the first layer and the external surface, in which the elements of reactive compound have not yet reacted with the gases. The method uses ultrasound to determine the position of an interface between the first and second layers to measure the progression of the diffusion of the gases through the sheath.

Abstract: This flexible fluid transport pipe includes an inner polymer sheath defining a fluid circulation passage with a central axis; at least one armor layer positioned outside the inner sheath; an inner carcass, positioned in the inner sheath, the inner carcass comprising a first bent tape defining a helical interstice emerging toward the central axis. The pipe includes a helical insert with a T-shaped cross-section comprising a rod inserted in the helical interstice and two wings protruding on either side of the rod to inwardly close off the helical interstice. The helical insert is formed from a second bent tape.
