Title (EN) A METHOD FOR FORMING A CLOSED CANAL IN A PIPE WALL, AND SUCH A PIPE
(FR) PROCEDE DE FORMATION D'UN CANAL CLOS DANS UNE PAROI DE TUBE, ET TUBE AINSI OBTENU
Abstract:
(EN) A method for the manufacture of a pipe (1) for use in petroleum exploitation, the manufacturing process comprising roll-forming of a steel plate (11) to form a hollow (0') with a longitudinal gap for being welded to form said pipe (1), the method characterized by the following steps: * said steel plate (11) having lateral edge surfaces (221, 222), in which along on or more of said lateral edge surfaces (221, 222) are formed longitudinal grooves (22, 22') thus forming first bridge parts (23, 23') comprising a first lateral edge surface (221i, 222i) along a first side of said groove (22, 22'), and thus forming a second lateral edge surface (221y, 222y) on a second side of said groove (22, 22'); welding of said first bridge parts' (23, 23') first lateral edge surfaces (221i, 222i), thereby joining said grooves (22, 22'), joining said second lateral edge surfaces (221y, 222y) to form a lid (3) to cover said grooves (22, 22') to form a canal (2) in the wall of said pipe (1).
(FR) Procédé de fabrication d'un tube (1) destiné à être utilisé en exploitation pétrolière, consistant à laminer une tôle d'acier (11) pour former un profilé creux (0') comportant un espace longitudinal qui est soudé pour former le tube (1), le procédé étant caractérisé en ce qu'il comprend les étapes suivantes : la tôle d'acier (11) comporte des surfaces de bord latérales (221, 222), le long d'une ou de plusieurs desquelles sont ménagées des rainures longitudinales (22, 22') formant des premières parties de raccord (23, 23') comprenant une première surface de bord latérale (221i, 222i) le long d'un premier côté de chaque rainure (22, 22'), et formant une deuxième surface de bord latérale (221y, 222y) d'un deuxième côté de chaque rainure (22, 22') ; les premières surfaces de bord latérales (221i, 222i) des premières parties de raccord (23, 23') sont soudées pour joindre les rainures (22, 22'), les deuxièmes surfaces de bord latérales (221y, 222y) sont jointes de façon à former un recouvrement (3) couvrant les rainures (22, 22') et à créer ainsi un canal (2) dans la paroi du tube (1).
