  • Design of Bolted Flanged Joints - Part 1: Example of application of the NF EN 1591 Standard
    -- Bernard Pitrou, Chairman of the CODETI's Executive Board (France).
    Bernard Pitrou has published this paper in the October 2003 issue of the SNCT quarterly Journal (Syndicat National de la Chaudronnerie, tôlerie et Tuyauterie industrielle). In this paper, he underlines that EN1591-1 is a more complete calculation method compared to traditional ones. For more information about this paper, please contact H. Zerres (h.zerres@sealeng.com).

  • Simulation of the pressure equipment behavior under thermal loading - Sealing application
    -- The 2002 ASME Pressure Vessels and Piping Conference, August 5-9 2002
    The performance of Finite Elements codes enables nowadays to perform low cost and very accurate 3D simulations of thermo-mechanical behavior of pressure equipment. It enables an accurate analysis of the leak-tightness problems. This paper describes simple bolted connections with gasket fitted with limiter ring, heat exchangers, and valves modeling as examples. Then, the economical interest of the application of such approaches are presented.

  • Comparative Presentation of the Taylor-Forge and the EN1591-1 calculation methods
    -- Pressure Vessel Research Council (PVRC) Workshop, Safety Harbor (FL, USA), February 2002
    Elaborated in the 30ies, the Taylor Forge method check the admissibility of Bolted Flanged Connections only for given calculation conditions. The European calculation standard EN1591 considers the whole flange-bolt-gasket system , enables to determine the internal forces and provides an allowable tightening range regarding leak-tightness and strength criteria.

  • Metal-to-metal Contact for Gasketed Assemblies
    Generalisation of EN1591 European Calculation Code for Circular Bolted Flanged Connections
    -- European Symposium on Pressure Equipment (ESOPE), Paris, October 2001
    Modeling the behavior of the Bolted Flange Connection (BFC) during operating conditions, the EN1591-1 calculation standard represents the best basis to develop new calculation methods for double gasketed joints and metal-to-metal contact BFC.
