Oil and gas industries including lower carbon energy - Corrosion-resistant alloy seamless products for use as casing, tubing, coupling stock and accessory material - Technical delivery conditions (ISO/DIS 13680:2026)

This document specifies the technical delivery conditions for corrosion-resistant alloy seamless products for casing, tubing, coupling stock and accessory material (including coupling stock and accessory material from bar) for two product specification levels:
PSL-1, which is the basis of this document;
PSL-2, which provides additional requirements for a product that is intended to be both corrosion and cracking resistant for the environments and qualification method specified in Annex G and in the ISO 15156 series or NACE MR0175.
This document contains no provisions relating to the connection of individual lengths of pipe. Demonstration of conformance to ISO 15156-3:2020 or NACE MR0175-2021 of material affected by end sizing, connection manufacture or welding operations is outside the scope of this document.
This document contains provisions relating to marking of tubing and casing after threading.
This document is applicable to the following five groups of products:
a)       group 1, which is composed of stainless alloys with a martensitic or martensitic/ferritic structure;
b)       group 2, which is composed of stainless alloys with a ferritic-austenitic structure, such as duplex and super-duplex stainless alloy;
c)        group 3, which is composed of stainless alloys with an austenitic structure (iron base);
d)       group 4, which is composed of nickel-based alloys with an austenitic structure (nickel base);
e)       group 5, which is composed of bar only (Annex F) in age-hardened (AH) nickel-based alloys with austenitic structure.

Industries du pétrole et du gaz, y compris les énergies à faible teneur en carbone - Produits sans soudure en acier allié résistant à la corrosion utilisés comme tubes de cuvelage, tubes de production, tubes-ébauches pour manchons et matériau pour accessoires - Conditions techniques de livraison (ISO/DIS 13680:2026)

Le présent document spécifie les conditions techniques de livraison des produits sans soudure en acier allié résistant à la corrosion, utilisés comme tubes de cuvelage, tubes de production, tubes-ébauches pour manchons et matériau pour accessoires (y compris les tubes-ébauches pour manchons et matériau pour accessoires en barres), pour deux niveaux de spécification de produit :
—    PSL-1, qui constitue la base du présent document ;
—    PSL-2, qui fournit des exigences supplémentaires pour un produit destiné à être à la fois résistant à la corrosion et à la fissuration pour les environnements et la méthode de qualification spécifiés à l'Annexe G et dans la série NACE MR0175/ISO 15156.
Le présent document ne contient aucune disposition relative au raccordement de longueurs de tuyau individuelles, à l'exception de ce qui est inclus à l'Annexe J. La démonstration de la conformité à la série NACE MR0175/ISO 15156 des matériaux affectés par le dimensionnement des extrémités, la fabrication des raccords ou les opérations de soudage ne relèvent pas du domaine d'application du présent document.
Le présent document s'applique aux quatre groupes de produits suivants :
a)    le groupe 1, qui est composé d'alliages inoxydables à structure martensitique ou martensitique/ferritique ;
b)    le groupe 2, qui est composé d'alliages inoxydables à structure ferritique austénitique, tels que les alliages inoxydables duplex et super-duplex ;
c)    le groupe 3, qui est composé d'alliages à base de nickel en solution solide à structure austénitique ;
NOTE      Les anciens groupes 3 et 4 de l'ISO 13680:2024 ont été regroupés dans le groupe 3 ci-dessus pour s'aligner sur la série NACE  MR0175/ISO 15156. Il n'y a plus de groupe 4. Le groupe 5 reste sans aucun changement afin d'éviter toute confusion avec les éditions précédentes du présent document.
d)    le groupe 5, qui est uniquement composé de barres (Annexe F) dans les alliages à base de nickel durcis par vieillissement à structure austénitique.

Naftna in plinska industrija, vključno z nizkoogljično energijo - Nevarjeni izdelki iz korozijsko odpornih zlitin, ki se uporabljajo kot zaščitne, proizvodne in priključne cevi ter pribor - Tehnični dobavni pogoji (ISO/DIS 13680:2026)

Ta dokument določa tehnične pogoje dobave za brezšivne izdelke iz korozijsko odpornih zlitin za ohišja, cevi, material za spojke in dodatni material (vključno z materialom za spojke in dodatnim materialom iz palic) za dve ravni specifikacije izdelkov:
PSL-1, ki je osnova tega dokumenta;
PSL-2, ki določa dodatne zahteve za izdelek, ki je namenjen tako odpornosti proti koroziji kot razpokam v okoljih in metodah kvalifikacije, določenih v Prilogi G in v seriji ISO 15156 ali NACE MR0175.
Ta dokument ne vsebuje določb, ki bi se nanašale na povezovanje posameznih dolžin cevi. Dokazovanje skladnosti z ISO 15156-3:2020 ali NACE MR0175-2021 za material, ki ga prizadenejo postopki končne obdelave, izdelave povezav ali varjenja, ni v okviru tega dokumenta.
Ta dokument vsebuje določbe, ki se nanašajo na označevanje cevi in ohišij po navoju.
Ta dokument se uporablja za naslednjih pet skupin izdelkov:
a) skupina 1, ki jo sestavljajo nerjavne zlitine z martenzitno ali martenzitno/ferritno strukturo;
b) skupina 2, ki jo sestavljajo nerjavne zlitine s ferritno-avstenitno strukturo, kot so duplex in super-duplex nerjavne zlitine;
c) skupina 3, ki jo sestavljajo nerjavne zlitine z avstenitno strukturo (železova osnova);
d) skupina 4, ki jo sestavljajo zlitine na osnovi niklja z avstenitno strukturo (nikljeva osnova);
e) skupina 5, ki jo sestavljajo samo palice (Priloga F) v starostno utrjenih (AH) zlitinah na osnovi niklja z avstenitno strukturo.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Oil and gas industries including lower carbon energy —
Corrosion-resistant alloy seamless products for use as casing,
tubing, coupling stock and accessory material — Technical
delivery conditions
WARNING — It is the purchaser's responsibility to specify the product specification level (PSL),
corrosion-resistant alloy (CRA) group, category, grade, delivery conditions and any other requirement
in addition to those specified herewith to ensure that the product is adequate for the intended
service environment. The NACE MR0175/ISO 15156 series should be applied when making specific
requirements for H S-containing environments; see Annex G. It is the product user's responsibility
to ensure that the product is suitable for the intended application with respect to all environmental
degradation threats during both normal operation and system upsets. Not all PSL-1 categories and
grades can be made cracking resistant in accordance with the NACE MR0175/ISO 15156 series and
are, therefore, not included in PSL-2.
1 Scope
This document specifies the technical delivery conditions for corrosion-resistant alloy seamless products
for casing, tubing, coupling stock and accessory material (including coupling stock and accessory material
from bar) for two product specification levels:
— PSL-1, which is the basis of this document;
— PSL-2, which provides additional requirements for a product that is intended to be both corrosion and
cracking resistant for the environments and qualification method specified in Annex G and in the NACE
MR0175/ISO 15156 series.
This document contains no provisions relating to the connection of individual lengths of pipe, except what is
included in Annex J. Demonstration of conformance to NACE MR0175/ISO 15156 series of material affected
by end sizing, connection manufacture or welding operations is outside the scope of this document.
This document is applicable to the following four groups of products:
a) group 1, which is composed of stainless alloys with a martensi
