Abstract
A pipe for transporting gas, notably carbon dioxide, includes at least one tubular element, tubular element consisting of a juxtaposition of concentric layers including, from inside to outside, at least one sealing layer, a wall including a prestressed concrete layer and at least one circumferential mechanical reinforcement layer. Furthermore, the concrete making up prestressed concrete layer is selected from among the ultra-high performance fibre-reinforced concretes (UHPFRC).
Claims14
A pipe for transporting gas, comprising at least one tubular element, the tubular element comprising a juxtaposition of concentric layers comprising, from inside to outside, at least one sealing layer, a prestressed concrete layer and at least one circumferential mechanical reinforcement layer, wherein the concrete making up the prestressed concrete layer is selected from among ultra-high performance fibre-reinforced concretes comprising a concrete reinforced with metallic and/or polymer fibres and having a compressive strength greater than 130 MPa.
