Beschreibung
Zusammenfassung:	The invention relates to a method for manufacturing a tubular pipe for transporting hydrocarbons, wherein said method comprises a) forming a polymer material pressure sheath (14), having an outer surface (18) and an inner surface (16) defining an inner flow space (11); b) winding a metal wire at a short pitch around said tubular pressure sheath (14) such as to form turns (22) defining consecutive intervals (30) therebetween; c) winding a plurality of armoring pull wires (25) at a long pitch around said turns (22); and d) bringing said inner flow space (11) to a pressure P greater than a given pressure Pd, while simultaneously bringing said pressure sheath (14) to a temperature T greater than a given temperature Td such as to obtain a low amplitude for the radial deformations at said intervals (30).
