Weldable structural steels for fixed offshore structures - Technical delivery conditions - Part 3: Hot finished hollow sections
This document specifies requirements for weldable structural steels made of hot finished seamless and high frequency welded hollow sections to be used in the fabrication of fixed offshore structures.
The following thickness limitations are given in this standard:
- for seamless hollow sections up to and including 65 mm;
- for HFW hollow sections up to and including 25,4 mm.
Greater thicknesses can be agreed, provided the technical requirements of this European Standard are maintained.
This European Standard is applicable to steels for offshore structures, designed to operate in the offshore sector but not to steels supplied for the fabrication of subsea pipelines, risers, process equipment, process piping and other utilities. It is primarily applicable to the North Sea Sector, but may also be applicable in other areas provided that due consideration is given to local conditions e.g. design temperature.
NOTE This document has an informative Annex E on the prequalification of steels for fixed offshore structures in arctic areas.
Minimum yield strengths up to 770 MPa are specified together with impact properties at temperatures down to -40 °C.
Schweißgeeignete Baustähle für feststehende Offshore-Konstruktionen - Technische Lieferbedingungen - Teil 3: Warmgefertigte Hohlprofile
Dieser Teil der EN 10225 legt die Anforderungen an warmgefertigte nahtlose und HFW Hohlprofilen aus schweißgeeignete Baustähle fest, die zur Herstellung von feststehenden Offsore-Konstruktionen verwendet werden.
Folgende Dickenbeschränkungen werden in dieser Norm angegeben:
- Für nahtlose Hohlprofile bis zu 65 mm,
- Für HFW Hohlprofile bis zu 25,4 mm.
Größere Dicken können vereinbart werden, vorausgesetzt die technischen Lieferbedingungen dieser Europäischen Norm werden eingehalten.
Diese Norm gilt für Stähle für Offshore-Konstruktionen, die für den Offshore-Einsatz vorgesehen sind, jedoch nicht für Stähle zur Herstellung von Unterwasserpipelines, Steigleitungen (risers), Verfahrens-Ausrüstungen, Rohrsystemen und anderen Einrichtungen und Ausrüstungen. Sie gilt in erster Linie für den Bereich der Nordsee, kann jedoch auch für andere Gebiete angewendet werden, vorausgesetzt, dass die örtlichen Bedingungen, z. B. die Temperatur, genügend berücksichtigt werden.
ANMERKUNG Im Anhang G sind Vorprüfungen von Stählen für den arktischen Einsatz bei Offshore Konstruktionen angegeben.
Mindestwerte der Streckgrenze bis zu 770 MPa werden zusammen mit Werten für die Kerbschlagarbeit bis herunter zu Temperaturen von -40 °C angegeben.
Aciers de construction soudables destinés à la fabrication de structures marines fixes - Conditions techniques de livraison - Partie 3 : Profils creux finis à chaud
Le présent document spécifie les exigences applicables aux aciers de construction soudables fabriqués à
partir de profils creux sans soudure finis à chaud et de profils creux soudés par haute fréquence destinés
à la fabrication de structures marines fixes.
Pour cette norme, les limites d’épaisseur suivantes sont données :
- pour des profils creux sans soudure jusqu’à 65 mm inclus ;
- pour des profils creux soudés par haute fréquence jusqu’à 25,4 mm inclus.
Des épaisseurs plus importantes peuvent être convenues par accord, à condition que les exigences
techniques de la présente Norme européenne soient respectées.
Cette norme européenne s'applique aux aciers pour constructions marines exploitées sur le domaine
maritime européen, à l'exclusion des aciers fournis pour réaliser des oléoducs sous‐marins, conduites
montantes, équipement de procédés et autres tuyauteries de transport. Elle s'applique prioritairement
au secteur de la mer du Nord mais elle peut également s'appliquer dans d'autres zones dans la mesure
où les conditions locales sont dûment prises en compte, notamment la température de conception.
NOTE Le présent document contient une Annexe E informative pour la présélection des aciers destinés à la
construction de structures marines fixes dans les zones arctiques.
La norme spécifie les limites d’élasticité jusqu’à 770 MPa et les énergies de rupture en flexion par choc à
des températures jusqu’à – 40 °C.
Konstrukcijska jekla za varjene konstrukcije naftnih ploščadi - Tehnični dobavni pogoji - 3. del: Vroče izdelani votli profili
Ta del standarda EN 10225 določa zahteve za variva konstrukcijska jekla iz vroče izdelanih nevarjenih in visokofrekvenčno varjenih votlih profilov, ki se uporabljajo za izdelavo konstrukcij naftnih ploščadi.
V tem standardu so podane naslednje omejitve debeline:
– za nevarjene votle profile do vključno 65 mm;
– za visokofrekvenčno varjene votle profile do vključno 25,4 mm.
Dogovori za večje debeline so mogoči, če se ohranijo tehnične zahteve tega evropskega standarda.
Standard velja za jekla za konstrukcije naftnih ploščadi, projektirane za delovanje v priobalnem območju, vendar ne za jekla, dobavljena za izdelavo podmorskih cevovodov, dvižnih cevi, procesne opreme, procesnih cevovodov in drugih sredstev. Uporablja se predvsem na območju Severnega morja, lahko pa se uporablja tudi na drugih območjih, če se ustrezno upoštevajo lokalni pogoji, npr. temperatura.
OPOMBA: Na voljo je dodatek G o predizbiri jekel za konstrukcije naftnih ploščadi v arktičnih območjih.
Minimalne napetosti tečenja do 770 MPa so določene skupaj z nizkotemperaturnimi lastnostmi pri temperaturah do –40 °C.
