    Abstract - (Show below) - (Hide below)

    Le présent document spécifie les exigences essentielles à respecter pour la qualification de soudeurs dans le cadre de l'assemblage d'éléments de branchement de gaz combustible (hydrogène exclu) dans les installations situées en aval de l'organe de coupure général, lorsque les conditions suivantes sont simultanément satisfaites - les tubes et les pièces à assembler sont constitués: - soit d'un acier non allié ou faiblement allié dont la limite d'élasticité RpO,2 ou Rto,5 minimale spécifiée est inférieure ou égale à 290 MPa; 21,3 mm < diamètre extérieur < 219,1 mm; - soit d'un acier inoxydable austénitique; 33,7 mm < diamètre extérieur < 219,1 mm; - le procédé de soudage utilisé est un procédé à l'arc électrique ou oxyacéthylénique; - la pression maximale de service est inférieure à 4 bar. Les procédés de soudage concernés par ce document sont des procédés manuels par fusion à l'exclusion de tout procédé totalement mécanisé ou totalement automatisé.
