The present invention is a tubular structure for transporting a heat transfer fluid, particularly a refrigerant fluid, and at least i) a semi-crystal having a Tm1 measured in accordance with the 11357-3 (2013) standard of 160 ° C. or higher, particularly 170 ° C. or higher. Or at least one thermoplastic polymer P1 that is amorphous at 100 ° C. or more, preferably 120 ° C., in particular 140 ° C., measured in accordance with the 11357-2 (2013) standard and in contact with the fluid Layer (1) that does not contain fibers, ii) layer (2), and at least (a) semi-crystalline with Tm2 of 170 ° C. or higher or non-Tg2 of 100 ° C. or higher A layer (2) comprising a thermoplastic polymer P2, in particular a polyamide, or a polyolefin having a Tm of greater than 100 ° C .; (b) continuous fibers, wherein the polymer P2 is P1 Unlike one as or P1, if different, the polymer P1 and P2 are attached at least partially to each other, about the tubular structure. |
