ISO 15590-1:2024

Oil and gas industries including lower carbon energy — Factory bends, fittings and flanges for pipeline transportation systems — Part 1: Induction bends

This document specifies the technical delivery conditions for bends made by the induction bending process for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623. This document is applicable to induction bends made from seamless and welded pipe of unalloyed or low-alloy steels. NOTE These are typically C-Mn steels or low-alloy steels that are appropriate for the corresponding level and grade of line pipe in accordance with ISO 3183. This document specifies the requirements for the manufacture of two product specification levels (PSLs) of induction bends corresponding to product specification levels given for pipe in ISO 3183. This document is not applicable to the selection of the induction bend PSL. This document is not applicable to pipeline bends made by other manufacturing processes.

Industries du pétrole et du gaz, y compris les énergies à faible teneur en carbone — Coudes d'usine, raccords et brides pour systèmes de transport par conduites — Partie 1: Coudes fabriqués par induction

Le présent document spécifie les conditions techniques de livraison des coudes fabriqués par le procédé de cintrage par induction et destinés aux systèmes de transport par conduites des industries du pétrole et du gaz naturel définis dans l'ISO 13623. Le présent document est applicable aux coudes cintrés par induction, fabriqués à partir de tubes soudés et non soudés, en aciers non alliés ou faiblement alliés. NOTE Il s'agit généralement d'aciers C-Mn ou d'aciers faiblement alliés adaptés au niveau et à la nuance correspondant au tube de conduite, conformément à l'ISO 3183. Le présent document spécifie les exigences de fabrication de deux niveaux de spécification de produit (PSL) des coudes cintrés par induction, correspondant aux niveaux de spécification indiqués pour les tubes dans l'ISO 3183. Le présent document n'est pas applicable à la sélection du niveau de spécification des produits (PSL) cintrés par induction. Le présent document n'est pas applicable aux coudes de conduites fabriqués par d'autres procédés.

L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
