Abstract
The present invention relates to a pipe for transporting gas, notably carbon dioxide, comprising at least one tubular element, tubular element (1) consisting of a juxtaposition of concentric layers comprising, from inside to outside, at least one sealing layer (5), a wall including a prestressed concrete layer (6) and at least one circumferential mechanical reinforcement layer (8). Furthermore, the concrete making up prestressed concrete layer (6) is selected from among the ultra-high performance fibre-reinforced concretes (UHPFRC).
