Any Complexity. Bolted Flange joint Bolts, apart from the load of preliminary tension (bending force) and torsion (if hydraulic or electric torque wrench is not applied), are subject to extra stretching or relieving, and Bending [7]. The ASME code specifies two distinct loading conditions for analysis, based on two gasket parameters: the yield factor, y, defined as the minimum gasket stress that causes the gasket material After stress analysis of a piping system is complete, a report package is created. Results from parametric studies are presented for various flange mating-surface waviness distributions and amplitudes An up-to-date and practical reference book on piping engineering and stress analysis, this book emphasizes three main concepts: using engineering common sense to foresee a potential piping stress problem, performing the stress analysis to confirm the problem, and lastly, optimizing the design to solve the problem. 3 ) What is sure is when you calculate a bolted flange connection as per Piping Stress Analysis.

Figure-1: Flange Alignment Pro b l e m (discovered after r e movi n g bolts). A "Stress-Strain" analysis is not banned by ASME VIII, since Div 1 describes it in Appendix S: "Such analysis is one that considers the changes in bolt elongation, flange deflection and gasket load that take places with the application of internal pressure, starting from the prestressed condition". In an axisymmetric analysis the bolts and the perforated flange must be modeled properly. Step-1: Contact between flange top surface and bolt bottom and gasket is initiated by applying a small initial axial displacement at the bolt bottom. In response to engineer demand for a Flange Rescue Gasket for sub-sea use, and analysis of the challenges of this environment, we adapted the FRG with additional functionality to promote safe practice in this environment.

For this reason, the analysis of stresses and deflections in a beam is an important and useful topic. A pipe stress analysis is performed to verify that the piping system is routed and supported properly. It is best not to try to do this all at one sitting, because you are likely to get frustrated at the slowness of the truing and tensioning process. The 3-D NX MODEL model was designed in NX8. 0 Guided Cantilever Method For an 'L' shaped pipe work, from the structural theory, the permissible deflection, 6 is given as: Where: 6 = lateral deflection (mm) L If you are looking for training courses in Piping stress analysis, Process Piping Design (), or Engineering Services; Little P.
