Title:	Statische Berechnung von verzweigten Rohrleitungen am Beispiel eines Manifolds
Abstract:	Für die Auslegung von Rohrleitungen für Flüssigkeiten und Gase werden häufig die ASME B31 Codes verwendet (American Society of Mechanical Engineers). Eine Alternative zur ASME B31 ist die europäische Norm EN 13480. Die Spannungen in komplexen Rohrleitungssystemen werden üblicherweise mit Stabmodellen berechnet. Die Steifigkeit der Bögen und lokale Spannungen an Abzweigern werden mittels Flexibilitätsfaktoren und Spannungsintensitätsfaktoren (SIF) berücksichtigt. In diesem Beitrag wird das Bemessungskonzept für verzweigte Rohrleitungen am Beispiel eines Manifolds (Verteilrohrleitung) vorgestellt. Ein Teil der Rohrstatik ist der Spannungsnachweis der Abzweigstücke. Stress analysis of branched piping systems using the example of a manifold. For the design of pressure piping systems for liquids and gas the ASME B31 Codes are commonly used (American Society of Mechanical Engineers). An alternative to the ASME B31 is the European standard EN 13480. The stresses in complex piping systems are usually analyzed with beam models. The stiffness of bends and local stresses at pipe branches are considered by flexibility factors and stress intensification factors (SIF). In this paper the stress analysis concept of piping systems is presented using the example of a manifold. One part of the pipe stress analysis is the code compliance check of pipe branches.
