Abstract
The present disclosure relates to a flexible tubular pipe (1) of the unbonded type and including, from the inside to the outside, an internal carcass (2), first and second polymeric sheaths (3, 4), at least one tensile armor layer (6, 7) and a polymeric sealing sheath (8) and also at each of its ends, a connecting endpiece (10) comprising i.a., a tubular sleeve (15). The tubular sleeve (15) of a first endpiece (10) includes means (30, 31, 32) for draining the gases from the gap (25) between the sheaths (3, 4) towards the outside of the pipe (1) and the tubular sleeve of the second endpiece (10) including means for draining the gases from the gap (25) between two sheaths (3, 4) towards the outside or towards the inside of the pipe (1).
