Les jonctions (10, 11, 14) des éléments adjacents (1) se présentent sous la forme de joints de dilatation et sont soudées (2, 6) sur leur longueur. Des canalisations d'essai tubulaires (40) sont agencées dans les joints de dilatation (19, 20). Après achèvement de la garniture d'étanchéité, un gaz rare est introduit dans les canalisations d'essai (40), et la garniture et les jonctions soudées (10, 11, 14) sont explorées. L'échappement de gaz rare révèle la présence d'une fuite.
