Flexibility factors for small (d/D<1/3) branch connections with external loadings
A piping system analysis is accurate only to the extent that the flexibilities of all portions of the piping system are accurately known. The use of a ''conservative'' flexibility factor is not possible because such a factor cannot be defined. Branch connections require a definition of flexibility factor which is conceptually different than commonly used for curved pipe. An appropriate definition for the flexibility factors of branch connections is presented. The background of the present Code formulations of flexibility factors for branch connections is discussed. Additional theoretical data and test data are summarized. Recommendations are given for revisions to Code formulations for handling the flexibility of branch connections in a piping system analysis.
