Effect of Thermal and Mechanical Loads On A Non Parallel Face Flanges Using Finite Element Analysis

Abstract

The flanged joint is one of the weakest elements on the piping system because of leakage. The leakage free joint is the target of the standard codes and many analytical and experimental studies. The codes usually focus on the conventional flanged joints containing gaskets. The gasketed joint which is classified in the standard codes was studied under different operating conditions to investigate its performance and its sealing capability. The non-parallel face flanged joint has been studied under different mechanical loads to be developed and it showed high efficiency than the conventional joint. The present paper studies the non-parallel face flanges as a 3D finite element model to investigate the behaviour of the joint under combined mechanical and thermal loading. The suggested model for the joint was established for different flange thicknesses under various operating temperatures and internal pressures.
