(Main)Steel pipes for pipelines for combustible fluids - Technical delivery conditions - Part 2: Pipes of requirement class B
Steel pipes for pipelines for combustible fluids - Technical delivery conditions - Part 2: Pipes of requirement class B
This European Standard specifies the technical delivery conditions for seamless and welded steel pipes for the on land transport of combustible fluids primarily in gas supply systems but excluding pipeline applications in the petroleum and natural gas exploration and production industries. It includes more stringent quality and testing requirements than those in EN 10208-1.
NOTE 1 Steel pipes for pipeline transportation systems within the petroleum and natural gas exploration and production industries are covered by ISO 3183 [1]. This standard specifies products with the same (and additional) strength levels and partly similar (but not identical) requirements as EN 10208-1 and EN 10208-2 and is with two additional annexes specifying deviating or additional requirements also published as API Spec 5L [4].
NOTE 2 This European Standard does not apply to cast steel pipe.
Stahlrohre für Rohrleitungen für brennbare Medien - Technische Lieferbedingungen - Teil 2: Rohre der Anforderungsklasse B
Diese Europäische Norm legt die technischen Lie¬ferbedingungen für nahtlose und geschweißte Stahlrohre für den Transport brennbarer Medien an Land, vorzugsweise für Gasversorgungssysteme, fest, schließt aber Anwendungen in der Erdöl und Erdgasindustrie aus. Sie enthält Qualitäts und Prüfanforderungen, die über die in EN 10208 1 fest¬gelegten hinausgehen.
ANMERKUNG 1 Rohre für Rohrleitungstransportsysteme zur Anwendung in der Erdöl und Erdgasindustrie sind in ISO 3183 festgelegt. Dies Norm spezifiziert Erzeugnisse mit demselben (und einem erhöhten) Anforderungsniveau und teilweise ähnlichen (aber nicht identischen) Anforderungen wie EN 10208 1 und EN 10208 2. Sie wurde mit zwei zusätzlichen Anhängen, in denen abweichende oder Zusatzanforderung festgelegt sind, auch als API Spec 5L [4] veröffentlicht.
ANMERKUNG 2 Diese Europäische Norm gilt nicht für Stahlguss¬rohre.
Tubes en acier pour conduites de fluides combustibles - Conditions techniques de livraison - Partie 2: Tubes de la classe de prescription B
La présente Norme européenne donne les conditions techniques de livraison de tubes en acier soudés et
sans soudure pour le transport terrestre de fluides combustibles principalement dans les systèmes
d'adduction de gaz mais elle exclut les applications mettant en oeuvre des canalisations dans les industries
d'exploration et de production de pétrole et de gaz naturel. Elle inclut des prescriptions de qualité et d'essai
plus strictes que celles de l'EN 10208-1.
NOTE 1 Les tubes en acier pour les systèmes de transport par canalisation dans les industries d'exploration et de
production de pétrole et de gaz naturel sont couverts par l'ISO 3183 [1]. La présente norme spécifie des produits avec les
mêmes niveaux de résistance (et des niveaux supplémentaires) que ceux des EN 10208-1 et EN 10208-2 et des
prescriptions partiellement similaires (mais pas identiques) à celles de ces normes. Elle comporte deux annexes
supplémentaires spécifiant des prescriptions déviantes ou additionnelles également publiées comme API Spec 5L [4].
NOTE 2 La présente Norme européenne n'est pas applicable aux tubes en acier moulé.

Introduction It was the intention, when preparing this document, to avoid specifying the quality of line pipe to be used for a particular application. However, it was recognized that there are several quality levels commonly used, and it was decided to reflect these in the standard by the differentiation between two quality levels. Firstly, the need was recognized to provide a basic quality level. This is designated requirement class A and considered in EN 10208-1. Secondly, many purchasers impose requirements additional to the basic standard, for instance concerning toughness and non-destructive inspection. This approach is common, for example, for transmission pipelines. Such enhanced requirements are addressed in requirement class B and considered in EN 10208-2. For offshore applications and other applications outside the scope of EN 10208-1 and EN 10208-2, other standards may be applicable, e.g. ISO 3183 [1]. The Charpy impact energy requirements in this document have been derived from established data, in accor-dance with EPRG recommendations [2], and are intended to prevent the occurrence of long running shear fracture in pipelines transporting clean, dry natural gas. It is the responsibility of the designer to decide whether these energy requirements suffice for the intended application. For example, rich gas or two-phase fluids may require additional testing to be carried out. For pipes of requirement class B, a weld efficiency factor of 1,0 can be used in design calculations, due to the conditions specified for the manufacture of the pipes and for the testing of the tubes. The selection of the requirement class depends on many factors: the properties of the fluid to be conveyed, the service conditions, design code and any statutory requirements should all be taken into consideration. Therefore this document gives no detailed guidelines. It is the ultimate responsibility of the user to select the appropriate requirement class for the intended application. NOTE This document combines a wide range of product types, dimensions and technical restrictions in accordance with the functional requirements for gas supply systems referred to in EN 1594 [3].
