A method and apparatus for inhibiting corrosion in strings of tubulars, the method and apparatus comprising the steps of coupling a first tubular (13) having a first tubular end (13b) to a second tubular (14) having a second tubular end (14b) using a coupling (12), the method comprising the steps of inserting the first tubular (13) into the coupling, placing a spacer (20) comprising a first member (30) and a second member (40) in the coupling (12) and on to the first tubular end (13b), inserting the second tubular (14) into the coupling (12), the second tubular end (14b) abuttin g the spacer (20) moving the first member (30) relative to the second member (40).
L'invention concerne un procédé et un appareil permettant d'empêcher la corrosion dans des colonnes d'éléments tubulaires, le procédé et l'appareil comprenant les étapes consistant à coupler un premier élément tubulaire (13) ayant une première extrémité tubulaire (13b) à un second élément tubulaire (14) ayant une seconde extrémité tubulaire (14b) à l'aide d'un couplage (12), le procédé comprenant les étapes consistant à insérer le premier élément tubulaire (13) dans le couplage, placer une entretoise (20) comprenant un premier élément (30) et une second élément (40) dans le couplage (12) et sur la première extrémité tubulaire (13b), insérer le second élément tubulaire (14) dans le couplage (12), la seconde extrémité tubulaire (14b) venant buter contre l'entretoise (20), déplaçant le premier élément (30) par rapport au second élément (40).
