The invention concerns a pipe component made of a metallic material for use in a high-pressure process comprising an inner pipe (1), a jacket (2) surrounding the inner pipe (1), an annular space (3) bounded by the outer surface of the inner pipe (1) and the inner surface of the jacket (2), and a connecting element (6) on at least one pipe end for connecting the pipe component to another component. The jacket (2) has at least one inlet (4) and at least one outlet (5) for a heat transfer fluid. The annular space (3) axially extends up to the connecting element (6) and is bounded and sealed by the connecting element (6). The connection between connecting element (6), inner pipe (1) and jacket (2) is made in an additive manufacturing process. L'invention concerne un élément de tuyau constitué d'un matériau métallique destiné à être utilisé dans un procédé haute pression comprenant un tuyau interne (1), une chemise (2) entourant le tuyau interne (1), un espace annulaire (3) délimité par la surface externe du tuyau interne (1) et la surface interne de la chemise (2), et un élément de liaison (6) sur au moins une extrémité de tuyau pour raccorder l'élément de tuyau à un autre élément. La chemise (2) présente au moins une entrée (4) et au moins une sortie (5) destinées à un fluide caloporteur. L'espace annulaire (3) s'étend axialement jusqu'à l'élément de liaison (6) et est délimité et fermé par l'élément de liaison (6). La liaison entre l'élément de liaison (6), le tuyau interne (1) et la chemise (2) est réalisée dans un procédé de fabrication additive.
