Background on the development and application of high pressure “large branch ratio” three way tee style hot tapping and plugging fittings on large diameter (16”–54”) pipelines and pressure piping systems in Canada. Examines the limitations and problems in current design codes, for large ratio branch connections, and the good engineering practiced applied based on simple shell finite element analysis.
