Abstract

The aim of this paper is to revisit the pressure reduction effect in smooth piping elbows under moment loading. A brief review of historical studies and an explanation of the origins of the effect is followed by an overview of an extensive series of detailed finite element analyses, carried out by the authors, which re-examines the well known Rodabaugh and George design factors that are widely used in piping Design Codes.
