Proc. ASME. PVP2022, Volume 2: Computer Technology and Bolted Joints; Design and Analysis, V002T02A026, July 17–22, 2022
Paper No: PVP2022-83754
... to further develop this pipe strain demand assessment by including variable effects of internal pressure and temperature of steel pipes buried in soils of different stiffness. The developed strain demand criterion considers inelastic material behaviour for different grades of steel pipe, as well as bi-linear...

... by steam or internal pressure can easily be estimated by a conventional FEM code. However estimation of system load caused by thermal expansion of pipe materials is difficult because of the complex structures of piping system. In this study, we developed a three-dimensional FEM code which can estimate both...
