Abstract

Leakage in Gasketed Flanged Joints (GFJs) have always been a
great problem for the process industry. The sealing performance of a
GFJ depends on its installation and applied loading conditions. This
paper aims to finding the leak rate through ANSI class#150 flange
joints using a compressed asbestos sheet (CAS) gasket under
combined structural and thermal transient loading conditions using
two different leak rate models and two different bolt-up levels. The
first model is a Gasket Compressive Strain model in which strains
are determined using finite element analysis. The other model is
based on Porous Media Theory in which gasket is considered as
porous media. Leakage rates are determined using both leak rate
models and are compared against appropriate tightness classes and
the effectiveness of each approach is presented.
