The tendency of rings of line pipe to open or close upon being longitudinally severed results from circumferential residual stresses in the pipe. The objectives of this work was to:
(1) To determine the nature and magnitude of the residual…
This report summarizes the results of additional secondary-stress projects carried out by companies participating in a cooperative effort to obtain more knowledge of secondary stresses in gas transmission systems. Projects summarized in this report…
This report analyzes 15 pipeline locations to obtain the secondary stresses from pressure, thermal, and external loading. The purpose of this study was to examine the significance of these stresses in relation to the design and operation of…
