Abstract:
A pipe (10) including an inner corrugated tube (16) having an axis A-A′, defining a plurality of corrugations (30) leading radially towards the axis (A-A′) and at least one tensile armor layer (18), arranged around the corrugated tube (16). It includes at least one thermal insulation layer (44, 46), arranged around the armor layer (18). The pipe (10) comprises an inner sheath (14) for guiding the flow of cryogenic fluid arranged in the corrugated tube (16), the inner sheath (14) being made up of a plurality of cylindrical segments (50). Each cylindrical segment (50) of the inner sheath (14) covers a plurality of successive corrugations (30) of the corrugated tube (16) and includes an outer abutment (54) for axial wedging received in a corrugation (30) of the corrugated tube (16).
