EN 13480-3:2012

Metallic industrial piping - Part 3: Design and calculation

1.1 The purpose of EN 13480 is to define the requirements for design, manufacture, installation, testing and inspection of industrial piping systems and supports, including safety systems, made of metallic materials (but initially restricted to steel) with a view to ensure safe operation. 1.2 EN 13480 is applicable to metallic piping above ground, ducted or buried, independent of pressure.

Metallische industrielle Rohrleitungen - Teil 3: Konstruktion und Berechnung

1.1 Zweck dieser EN 13480 ist die Festlegung von Anforderungen an Konstruktion, Herstellung, Verlegung und Prüfung industrieller Rohrleitungen einschließlich Sicherheitseinrichtungen, aus metallenen Werkstoffen (aber zunächst auf Stähle beschränkt), für sichere Betriebsbedingungen. 1.2 Die vorliegende Norm gilt für oberirdische oder in Kanäle verlegte oder erdgedeckte Rohrleitungen aus metallenen Werkstoffen unabhängig vom Druck.

Tuyauteries industrielles métalliques - Partie 3: Conception et calcul

1.1 L'objectif de EN 13480 est de définir les exigences relatives à la conception, la fabrication, l'installation, le contrôle et l'inspection des réseaux de tuyauteries industrielles, y compris des systèmes de sécurité, réalisés à partir de matériaux métalliques (mais pour l'instant limité aux aciers), dans le but de garantir la sécurité lors de leur utilisation. 1.2 EN 13480 est applicable aux tuyauteries métalliques aériennes, en caniveau ou enterrées, indépendamment de la pression.
